Comfortable, full featured, lightweight pack under 2.5 lbs. With an internal frame, this ultralight pack does not sacrifice comfort for weight. Great on the hips and shoulders and the suspension back panel.


  • Lightweight (2 lb 6 oz)
  • Removable lid/converts to daypack
  • Breathable back panel
  • Double entry mesh side pockets
  • Quality construction


  • No incl raincover
  • Limitation of bottom compression straps
  • Slightly more $$ than some other UL packs


I purchased this earlier in the spring, shortly after its release.  I have about 120 +/- hours with this pack and will post my review of my experience up to this point. I prefer to describe where I’m at in the life of the pack in trail hours as that seems more appropriate in terms of a piece of equipment which is worn. In essence this is early in the pack’s life, but I feel I have enough experience to give my two cents so far!

I am 5’9, 150 lbs., 32 in. waist and 18 7/8 in. torso. 

Pack Experience/Comparisons

Other info to note about my review/background. I have only borrowed packs in the past, the most recent being REI’s Flash 62 pack. This pre-2014 model comes in at just 3 lbs. for the men’s medium. A relatively inexpensive pack for the features and weight, it served me well and I’d recommend it to any new backpacker who wants to jump in but not spend $200+ for a pack.

I have used the GoLite Jam 50 which I really enjoyed too. At 1 lb. 14 oz., it felt like it was the weight of the world off of my shoulders (so to speak…18 total ounces saved!). The weight savings, great cost and comfort really got me to look at my gear closer and make a decision on my first pack purchase.

The 2014 Osprey Exos 58 is where I split the difference, literally in almost every way except for price. I had a 20% off coupon and $50 giftcard, I did my research and figured I’d give it a whirl. A few quick specs to keep in mind:

  • Advertised at 2 lb. 6 oz. (Don't have digital scale to compare)
  • Internal frame
  • Removable lid/new “FlapJacket” to properly cover top when lid is removed
  • Tensioned “Airspeed” backpanel to increase air flow
  • Reservoir compatible
  • Separate (non ice axe) rings for trekking poles

Construction & Durability

The pack material seems durable, definitely somewhere between the GoLite material and the Flash’s ripstop nylon. The mesh side pockets are always a place of concern if edges of a Platypus or trailside branches get caught. I have used my Nalgene bottles or older 70 oz. Camelback and these side pockets are no concern for me.

The most exterior compartment on the back is also mesh, the idea being that smaller items can just be wedged it after all has been packed such as trailside items or TP bag, etc.

The nylon material which makes up the rest of the pack is highly water resistant.  If it begins to lose a bit of its resistance, I plan on using some Nikwax TX.Direct, but I’m not all that concerned. Even on days when I do not expect rain, I just line my pack with a large trash bag. It makes it easy to take items in and out and also provides a better layer of waterproof capability between my pack exterior and belongings.

58 liter pack

With optional lid removed, embedded FlapJacket acting as new lid


I’ve tried several packs on before, either out on the trail or in the store. The true test is over the course of several miles on whether the pack is comfortable, rides, well and fits as expected. Naturally, pack weight is also a factor in this. Osprey gives a median, max weight of 35 lbs. in their range of 30-40.  I have not had plans to go above 30 lbs as I thought I’d fill up the 58 liters before I got close to that amount.

Most of the trail I had it about 25 lbs. something I thought was reasonable and test the UL aspect out against this weight.

Didn't take a before pic of what I incl above, but was something like this, plus a few other small items.

For my size, the medium fits like a glove. The hip belt is extremely comfortable and there is no pressure on my lumbar from the aluminum frame. This was the primary issue I had personally with the Flash. 

The foam shoulder straps also stand out a bit in that the foam material does not extend as long as typical shoulder straps.  Made of the same foam in the hip belt, it has not caused any chaffing or unnecessary pressure on my back, shoulders, chest, or armpits.

Hip belt pockets, pockets on each shoulder strap. Elastic, fits bars and cell phone well.

Something that must be mentioned when it comes to comfort is the trampoline suspension of the back panel.  It reminded me of my Mountainsmith day pack. This is a great feature and rates very high for me if I see it on a pack. Only the past two hikes or so while wearing the pack was it getting to be very hot and humid during the day, typically summer coming early after heavy rains.

The suspension is supposed to increase air flow over the back and not have a sweaty back and shirt right up against the pack.  While minimal, the trampoline does have slight “give” to it and also conforms well to my back.


I don’t feel there are any negative structural integrity issues with this suspension. Keep in mind that this still has an internal frame so if, by some chance, the suspense were cut horizontally, your back would be right up against the inner plastic support.

The hip belt pockets do protrude slightly, even when not filled, but I didn’t see this impact me when I walked with a normal gait. 

There is also an option to have the side compression straps to either go around the mesh side pockets or through (i.e. directly against the pack body).


Unique Features of the Design


One of the newer additions to the Exos was a removable lid. It attaches at three different points with a hook design. There should be no worry about the lid falling off when hiking or at rest.  When I’ve had the pack loaded and hardly carrying a thing, the attachments didn’t come loose on their own.


Three hooks like this are what keep the lid attached when in use.  Two on the side and one in the back.  The back hook is adjustable and the sides have three attachment loops to choose from depending on pack height.

Once removed there is a flap that can flip over and connect to the buckles which the original lid connected, in effect closing the opening and converting it into more of a daypack. A great addition if you keep toiletries or anything else you may just want to take with you after making camp. Just pack it in the lid and take it with you.

I also like the option to have access from the top as well as the side of each mesh side pocket.



While a small part of its design, there is a hoop on the shoulder strap and at the waist. It gives you the option to hook your trekking poles onto your pack. It can be removable…with a pair of scissors if I decide it’s not for me. See the video below:

Keep in mind that the compression straps at the bottom of the pack are not meant for anything other than lightweight gear. I recommend just a wide foam sleeping pad or something of the sort.  I put my Hubba Hubba through it (for curiosity’s sake) and the straps, length of straps (maybe something 6-7 inches in diameter once loaded), and weight distribution just doesn’t seem that good for options other than a pad. The hoops for the straps seem well made, but items heavier than a pound or two bouncing around…eh, won’t risk it.

Lastly, another small item, but the loop which is at the top of the pack is thinner than I would like, feels as though it should be wider and better secured. This is the loop that most packs are hooked to the wall in the stores. With it being an UL pack, it's understandable though that this doesn't need to be able to support 50 lbs., so I see that going for it.



For me this pack has all of the features of other UL packs and some. This is a great pack for either day hikes or longer thru hikes. I wouldn't be surprised to see this more and more on the PCT, AT, or CDT in the future. For those gram weenies (starting to become one myself), if you remove the top lid, you should be able to get the weight just an ounce or two over 2lbs and have about 52L capacity. That plus it's comfort, hip belt pockets, load lifters, and internal frame, I feel very comfortable and confident recommending this pack to others!

Great review! I have an REI Flash 65--when I got done modifying it, it was down to 1lb. 13oz. As far as the trekking pole holder goes, a few times a day, you just need a quick, short-term place to stick your poles while you eat a snack or shoot a video while hiking. Normally, I just carrying both in one hand and used the other, but this is a nice little feature.

Thanks, Jake, Eric, and G00SE! Very true about when you'd use that feature with the poles. It's just an easy way to get it out of your hands without taking off your pack. I may be able to figure out something else to do with hip and shoulder loop in the future too, so I'm keeping it for it now.

Can those shoulder loops fit water bottles? That'd be my first alternate use. Or swap out the dynamic bungee cord for something more static and use them to hold onto and rest your arms (especially since you don't use poles).

Eric, the shoulder loop can definitely fit a water bottle. It actually uses a toggle to make the loop larger and smaller. Largest diameter being about 4 inches, smallest about the size of a quarter, so a few different options there. Thanks for the advice!

One more thing about the EXOS 58. The best feature is its great trampoline mesh back panel. This is brilliance. As Osprey says, regarding UL backpacks, the weight saved by eliminating a frame is not worth the discomfort. AMEN!

I just bought an EXOS 58. After cutting off the "hiking pole loops" and adding side pockets I found it just right to replace my aging REI Cruise UL 60. The EXOS 58 is MUCH more comfortable. I've down a few training hikes with it loaded to 30 lbs. I love its adjustability and waist belt. My lumbar sea feels better with this pack.

Recently purchased the 2014 version of this model.

Rating: rated 4 of 5 stars
Source: bought it new
Price Paid: $220


Recently purchased the 2014 version of this model. Initial impressions are very good. Form, fit, and feature set are just right for most trips. A full featured, well ventilated design at under 3 lbs is quite a feat!


  • Lightweight
  • Sturdy harness
  • Comfortable
  • Versatile
  • Full featured


  • sleeping pad strap too short

I recently purchased this pack. I had a ULA Circuit in my sights and almost purchased it until I saw this pack had just been released to market. I could not believe that a M size 58 L @ 2lb 10oz fully featured pack rated for 38 lbs could be possible. When I saw this pack, I had to have it. 

Osprey Customer Service

I have used and basically worn out a 2004 Osprey Aether 60. My Aether 60 weighs 3 lbs 4 oz and I thought that was light! I am sending this pack back to Osprey where they have agreed to replace worn out straps, a draw string and buckles. They are doing this under warranty! Excellent service. 

When I called Osprey and mentioned to them that the sleeping pad strap on the Exos is too short to wrap around a Zpad, or anything similar, they agreed to provide me a solution. 

Function of Exos 58

My Exos 58 weighs 2 lbs 10 oz.  There are hip belt pockets on each side, and they are big enough to hold a camera, couple energy bars, gps, etc. The full featured hood pocket is fairly large, and it has an additional pocket underneath for wallet, keys, etc. 

There are two pockets, one on each shoulder strap for small items such as goo, energy bar, etc. There are two large mesh, two-way pockets on each side of the bottom of the pack. Finally there is a large exterior stretch mesh panel on the outside/front of the pack.  This is handy for anything wet, overflow gear, etc.

On the interior there is a hydration sleeve next to the backpanel. The sleeve has a handy buckle at the top to secure the water bag. A 2L water bladder fits perfectly.  There are two ports, one on the left and one on the right for your hose. The straps and buckles are all constructed with weight saving in mind.  The side compressionstraps are about 3/8" wide, and run in a Z-pattern up the each side the full length of the pack. The sleeping pad strap is made of the same material and threads through loops to form two larger loops where your pad, tent, etc can be secured at the bottom. 

The shoulder straps and hip belt are lightly but sufficiently padded, and are constructed of a breathable foam mesh. 

The aluminum tube frame runs the perimeter of the pack.  The tubing is about 1/4" in diameter and is very sturdy. The frame also supports the trampoline mesh back panel allowing for superb ventilation and comfort. 

I have loaded my pack up with 26 lbs, and found the fit and comfort to be excellent. The weight distribution to the hips is perfectly balanced. The pack bag sits well on the frame. The M size fits my 17 1/2" torso very well, even though the specs say the M range starts at 18" torso. 

I have not had the opportunity to use the pack on the trail yet, and will provide updates throughout. 

Initial impressions are very assuring that this pack is going to be very comfortable on the trail. The one thing I am most encouraged about is the ventilation in the back panel. 

Update on the performance of the Osprey Exos 58

I took this pack on a recent overnight trip. I found the construction to be quite sturdy. The frame is stiff and supportive, yet comfortable. I intentionally loaded it up with 32 lbs. I feel that this is maximum comfort range.

Any more and the pack would struggle to control and support the load. The shoulder straps, hipbelt, and compression straps all worked well to stabilize the pack and distribute the load. I was impressed and surprised at how strong the front pocket strap is. I inadvertently picked it up fully loaded by the pocket strap and it easily supported the weight. 

The feature that stood out the most while hiking is the mesh back panel. The fit was excellent, while airflow was practically unimpeded across my back keeping me quite dry and comfortable. I will especially love this feature on summer hikes.  


The hydration sleeve is very convenient and paired with the Osprey Hydraulics 2L bladder the fit is perfect. The ports for the hose are on left and right. I was able to thread a Sawyer mini water filter through the hole just barely, but it fit. Using the inline filter and the bladder together provides flexibility of a quick fill drinking system, and a gravity system while in camp. 

Throughout the 12 mile hike, I felt comfortable and making my usual "micro" adjustments while hiking was easy and the buckles worked smoothly. The hipbelt pockets are perfectly placed and the zippers were super smooth to operate. The side stretch pockets are very easily accessible while hiking and can easily hold a 20 oz drink bottle, tent poles and just about anything else. 

If I have a couple of issues, it would be with the top pocket. I believe that it is a bit large for the pack, and also I would like to see the top flap buckles a different color. This pack has a removable top pocket. This is a nice feature.  To accomodate the missing top pocket, you have a top flap permanently attached with identical buckles.  It is easy to confuse the flap buckles with the pocket buckles. 

So far I have seen no potential weak points where premature wear can occur. So far, I am pleased with the fit and function overall of the Exos 58 pack. 

UPDATE:  6/2/2014

Just finished a 40-mile hike in Uwharrie National Forest using this pack.  I can only say that the ventilated back panel kept me very comfortable the entire time. I could actually feel the air circulating between my back and pack. 

I also enjoyed how the pack held adjustment requiring on a tweak or two along the way. The pack suspension supported a 30 lb load comfortably throughout.  I finished my hike with no sore contact points. 

Overall this pack is a top performer.

How has your experience been with the straps at the bottom of your pacl for a sleeping pad or maybe tent? Supportive? Tight enough? Awesome review, very thorough!

12 months ago

Thanks Daniel, I should probably explain more about the sleeping pad straps. Actually thier is just one strap there threaded though loops. This pack is designed for the newer ultralight self inflaters. It adequately held my old Guidelite self inflator, but there is simply not enough strap to hold a zrest or something like that. I also would like the pad strap to be wider. Note in the photo that I have my pad at the bottom. had it been smaller, I could have put it through the two loops in the front (like my old Aether 60) and kept the pad off the ground.

12 months ago

Thanks for your review. I just got the new Exos 48 but have yet to get it out in the field, will try to post some initial thoughts as you have done. It weighed in a little more than advertised but still close to my goal of a 2 lb pack. I love the ventilation, especially for here in Florida. I don't plan to use the pad straps on the bottom, so it's good that they are removable. I also like that Osprey made the top lid easy to remove with integrated clips, rather than having to thread the nylon through buckles. Enjoy your pack!

This is a great all-around backpack if you don't overload…

Rating: rated 5 of 5 stars
Source: bought it new


This is a great all-around backpack if you don't overload it. With less than 35lbs of well-chosen gear, it works for both weekend and long haul trips, and you can manage 40lbs for a couple of days.


  • Lightweight
  • Great frame
  • Good balance


  • Pack material less durable than some

I'm a 5'7", 145 pound, 63-year-old woman who works in the backcountry in summer, usually for 6-8 days at a time. My pack has to be light enough to let me move quickly, but big enough to carry my personal and work gear. I can't carry the 55 pound loads that I did when I was younger.

After a year of frequent use, I have to say that the Osprey excels at the sub-35lb weight and sucks above that. At lower weight, it's well-balanced and fits solidly. At higher weight, the shoulder straps chafe and cut, even though most of the weight rests uncomfortably on your hips.

I just completed an 8-day, 80 mile hike in Patagonia (Torres del Paine "O" circuit) and the pack was able to haul all the gear I needed; I was miserable for 2 days, and fine the next 6. The pack is also doubling as my all-around travel back, being manhandled into busses and planes.

Organization is critical. The pack is a top loader, so you have to accept that a lot of stuff will be buried most of the day. That said, the two long outside pockets, the lid, the small side pockets, the hip-belt pockets, and the sort-of-beavertail pocket leave you enough options to keep everything you need handy if you think well in advance.  I found it balanced better with my tent (Big Agnes Fly Ck UL3, about 3.5 pounds) sandwiched between the top of the pack and the lid, rather than attached to the bottom.

I'm seeing some abrasion from encounters with rocks and busses, but no holes.  Given how light the material appears, I'm impressed with its durability. My favorite features are the airspeed frame, which holds the pack well enough away from your back that you don't get sweaty, and the 2 pound-6 oz base weight, which makes it practical to use the pack as a day pack when you're base-camping.

I've had a lot of packs in my life, and this i sthe first one I would replace with the same model if anything happened to it.

Rating: rated 4.5 of 5 stars
Source: bought it new
Price Paid: $169


This is an awesome pack. Not only is it the most comfortable pack I've ever owned, it's also lightweight and durable. I've loaded it to 55+ pounds comfortably, even on long hauls. In addition to the roomy interior pocket, it has easy external access for water bottles, rain jackets, ice axes, and sunglasses.


  • Comfortable
  • Lightweight
  • Durable

The best feature of the Osprey Exos is the comfort. The shoulder straps have surprisingly thin foam with lots of ventilation, and the hip belt is similar. Both combine to comfortably hold the weight snugly against your body. The back is a net that provides more than an inch of ventilation (unless you use a water bladder, in which case it can block the ventilation).  

The pack holds enough for 3-4 days in summer or a weekend in the winter. The pack has one large chamber for gear, and can be cinched down on top and on the sides to ensure a compact profile. The side compression straps are thin, yet strong, typical of the "just enough" approach used by Osprey.  

The pack has a full suite of external pockets and straps to hold your en-route gear. Two ice axe straps with quick-release bungees make for quick release. There is a stretchy front pocket that holds your rain jacket, two net water bottle pockets on the sides, and two vertical pockets on the front. I haven't really found a great use for these pockets, as anything you put in them will compete for room in the main pocket.

There are net zipper pockets on both sides of the hip belt that are great for sunglasses or lip balm, as well as a pocket good for an iPod or phone on the shoulder strap.  There is also a generous pocket on the top of the pack, with a document envelope in the interior.  

The pack has held up very well over two years of rugged use. Nothing has broken to date.


Lightweight, very comfortable, fantastic back system…

Lightweight, very comfortable, fantastic back system and lots of pockets.


  • lightweight
  • lots of pockets
  • very comfortable backsystem


  • none yet

Well to start, the back system is very good. I mean the way it is curved lets good air flow stopping your back from getting sweaty. The waist pockets are really big, lots of room I found for important things you need at hand.

The walking pole quick storage is a thing of brilliance, you compress the poles and put in the loops freeing your hands to map read etc. and all so the open back pocket, which is separate from the main pockets, is a very good idea. You put your wet tent or wet  clothes. If you lift the top hood underneath is a good size zipped pocket (for first aid, toiletries etc!) there is a whistle on the chest strap. Also on the shoulder strap there is a small pocket, i think it might be for a compass or a small mobile phone etc.

The rucksack i used before was a Golite Jam 50 liter which was great, but i noticed i was prone to a sweaty back in the summer. With the ospre exos 58 with its mesh and curved back this does not happen. You can also see the poles tucked in to the carry straps, which i can't stress how great a feature this is!


Excellent lightweight pack (not ultra light), great…

Excellent lightweight pack (not ultra light), great for weekend, multi-day, and through-hiking. Would definitely recommend assuming you can get the correct fit for your torso.


  • Lightweight
  • Fairly rugged if you don't thrash it
  • Well made


  • None for this version

Have been backpacking for over 50 yrs., mostly high Sierras.  Male, 165 lbs.  Excellent pack. Had the previous version and put 52 lbs in/on it for the JMT (enough for a 10 day stretch).

This model has a bunch of upgraded aspects. The older version top pack was difficult to detach. I sewed small quick release buckles on so it would come off easier and faster. This model they designed that into the top portion so it comes off and goes back on way easy. I sewed on a waist belt (3/4" webbing) with a quick release buckle so it is a fanny pack for day hikes. Works perfectly. Only adds a tiny bit in weight and a lot of function.

The shoulder straps and hip belt are reinforced quite a bit more, so much more comfortable. The 52 lbs in the older model was not at all comfortable. I regularly carry 48 lbs (enough for 6 days, including a tent/fly/ground cloth, bag and 3 1/2" sleeping pad, and expedition bear canister) for the first couple of days on trail and although it's overloaded by weight it is reasonably comfortable. When it gets down to 40 or less it's very comfortable.  

This one and the older one seem to be accurate in terms of volume. Everything adjusts easily.  The adjustable straps on the sides of the pack tighten the load and make it secure enough so it doesn't wobble around at all when the load gets lighter, and keeps the load correctly positioned on my back and hips.  

All in all, a pack that would only be improved upon if were even lighter. But if lighter it most likely wouldn't be as durable. This one will last if you take care of it. I don't scrape it around on the rocks and am careful with it in general.

This is an excellent light pack for UL backpackers…

Rating: rated 4.5 of 5 stars
Source: bought it new
Price Paid: 20% off REI retail


This is an excellent light pack for UL backpackers who can go for seven days with a starting load under 30 lbs (2014 model). This would make a great thru-hiker pack.


  • Very comfortable harness and belt
  • Excellent mesh back panel ventilation
  • Detachable lid for shorter day trips
  • Nice strap setup on pack bottom
  • Durable materials
  • Easy to compress W/side straps


  • More neutral colors would be nice. (Please!)
  • Osprey needs to sell optional side pockets
  • Pack bottom straps could be longer for holding CFC pads

I bought this pack to replace my aging REI Cruise UL 60 pack. I love the EXOS 58's comfort, even with 30 lbs.

The mesh back panel rides very comfortably and is cooler by far than my mesh covered foam REI back panel. 

Inside this single compartment pack is a small QR buckle to hold up your hydration bladder in its sleeve. Also there's a larger nylon webbing and QR buckle to pull the load in and up a bit. I have the same setup on my old Dana Designs Terraplane and like it a lot.

Outside are two small hip belt pockets  good for small tube of sunscreen, a small baseplate compass, etc. There are narrow "pockets on each shoulder strap. I use one for storing my Camelbak bite valve to keep it clean. Very handy for that purpose.

After some more trips I may remove the useless (to me) mesh side pockets since I carry my electrolyte bottle in a "Wet Rib" front pouch. I've already removed the hiking pole carrier loops. If my poles aren't in my hands then I'm at camp. 

This pack is a good combination of fairly durable materials, an ingenious frame and back panel and lightweight but very adequate straps and buckles. The choice of light hardware on this pack reminds me of the light hardware on my Tarptent Moment DW and Scarp 2, light and very durable. 

I purchased two (now discontinued) Granite Gear medium size side pockets. I like to keep gear in them that I may need quickly, such as 1st aid kit, water treatment kit, potty kit and stove gear. They attach nicely on the pack's side compression straps.

As another pro: Fully loaded, this is the approximately the largest pack an airline will let you carry on the plane. Any larger (ie. Osprey Atmos 65) and more often than not, they'll ask you to check it.

Yer keerect about Osprey's fit denis. It ain't fed everybody. But I'm 5' 10" and 180 lbs. So I'm "average" and their size Medium does fit me well.... EXCEPT that I have two mildly herniated lumbar discs and need the shoulder straps to NOT wrap around my shoulders but instead go right up to the pack so there is little to no weight on my spine. The shoulder straps merely balance the pack to keep it from falling backwards. To get this fit I have to use a size Large which works great.

I won this pack from a Timmy O'Neill slideshow raffle in Boulder, CO, and have used it for bouldering and stuck it in crashpads, been alpine sport climbing and hiked 8 miles with a rope on top without back problems, taken it traveling by plane for domestic trips, and fit a very large number of things in this back pack via the shape, efficient space, and wonderfully multi-purpose and accessible compartments. 

The back support is absolutely wonderful -- no corners stick in my back, no imbalances, great for quick loading and unloading and hiking.

My pack has withstood snow and rain and wind and months and stretching. I love it.

An overall great pack! Light, sturdy, feature rich, and comfortable. Keeps you cool in the summer and allows you to over stuff it in the winter. You will be looking for more days to take this sweet ride on the trail.


  • Light
  • Strong
  • Very breathable
  • Full of features


  • Hip belt is a little on the light side.

For the weight and an almost frameless pack, you can't get a more stiff ride that keeps the gear snug. I love this pack especially during the summer months with the wide open mesh back that allows your back to breath better than any other pack on the market.

Full of features not found on many packs, i.e. trekking pole quick storage, top lid, super tight compression straps, load lifter, hip belt sinch straps, and much more.

After waiting for it to hit the retail stores, I finally purchased this product. However, once loaded, this pack sagged horribly in back, making me feel like I was carrying a bag of rocks, although it was packed well.

The hiking pole attachment on the shoulder strap, cut into my arm, leaving an open wound, something I didn't need on the trail. I had about 22 lbs total in the pack, not even a large load by any standards.

I did like the many features on this pack, including the interior water sleeve, the hip belt pockets, that held everything I wanted them to, the side pockets, which made it simple to get at my water bottles and put them back in.

I love the unisex styling, as not all gals can use a women's specific pack. The hipbelt and shoulder straps were reasonably comfortable.

This pack is plenty big enough to hold anything one would need for a week long+ trip, if packed correctly. However it just isn't the pack for me.

Just what I needed! A very airy back, 1oz per 1lb carry range (40oz pack to 40lb max carry). Like most corporations it's hard for them to tell the truth as my 2014 medium Exos 58 was listed at 2lb 6 oz, but my two digital scales say 2lbs 10oz.

Stripped of yuppie add-ons and hood, it was to be 2lb 2oz per Osprey, but my digital deliars say 2lbs 6oz. I suppose if I take a knife to the various gimmick add-ons and straps it would be as they listed.

Nevertheless, it will have to do as I see and feel no other pack better. I used a 13oz beltless Jardine Golite Breeze for my PCT, AT & CDT thru-hikes and feel it's time to rest my shoulders and air out my back now.


  • Light frame
  • Airy frame back
  • Comfy straps and belt
  • Straps and belt are better than older Exos


  • 4 oz heavier than listed by Osprey
  • Too many gimmicky add ons
  • $220, knock it down $44 with a 20% off REI coupon

Very comfy for a 2lb 6oz pack. I like it better than my weekend trip pack Gregory Z55. I trimmed down to 3lb 2 oz. I have long awaited for such a pack like the Exos to be 2lbs or less. I'm almost ready to retire the use of beltless/frameless rucks like the Breeze.  

I was hoping to trim down the Exos to 2lbs or less, but Osprey got me believing my pack was 2lbs 2oz stripped until I took out the deliars. I figured I could trim off 2oz easy, but didn't realize it was over 4oz heavier per their claim.

No matter, it's light enough and comfortable to carry over 30lbs, unlike all the various ultralight cottage brands that most thru-hikers use that don't have the airy back feature like the Exos or can carry over 30lbs comfortably. I've tried them all and sometimes you just have to go heavier to get the comfort you want. Otherwise just use a frameless and beltless sub 1lb ruck and keep your total pack weight under 20lbs (7lb or less base weight).

Great design, so well thought out. It just didn't fit me (size long). I have a 36" waist, and I thought the belt would cut me in two. Unlike a lot of Osprey packs, you can't change these belts. The pack is working great for a buddy of mine with a 32" waist.

Waited for this pack for months after I read it was coming in January -- finally got one, but it came with a hole in the mesh right above the shoulder straps.

After much tadoo, finally got it repaired (Osprey just stitched the hole closed, I could have done that!!), but now the mesh pockets are fraying around where they are sewed to the zipper. I've used it only on 20 day hikes or so, also I see wear on the bottom where the frame is covered with fabric, even though I'm careful where to set it.

Bummer, Osprey!!!!

I don't think this will be a very durable pack. I used this pack for one weekend trip, with a load of 22 lbs. When I got back, I noticed that the mesh on the back was beginning to come apart at the side seams.

Comfort-wise, it was okay but not great. 



A follow-up report would have been welcome.
