Not too small...not too large...the UL Goldie-Locks of packs!
- Front Pocket
If I could only own one pack…the Ohm 2.0 is the pack I would choose…and more often than not…it is the pack I choose for trips ranging between 2-5 days. Utilizing a carbon-fiber pole to transfer weight to the hips the Ohm 2.0 is a fully functional internally framed backpack.
However…on trips where an internal frame is unnecessary users will find the fully removable carbon-fiber pole an added bonus…converting a thru-hike pack into an extremely durable frame-less pack in a matter of seconds. It is versatility such as this…in combination with the incredibly comfortable carry of the Ohm 2.0 that make it one of my favorite packs to date!
Out of the packaging the original weight of my size large pack with medium hip-belt was 902 grams or almost 32 ounces. As with anything I buy…there was a bunch of silliness that I immediately went about removing 1) hydration sleeve 2) hand-loops 3) water bottle holders 4) foam pad 5) security pocket…in all a removed 138 grams or almost 5 ounces of nonsense for a new pack weight of 764 grams or almost 27 oz.
There may be further subtractions in the future…but all of these items are easily removed and can be re-installed later…so further removal will require more consideration (thinking of removing trekking pole loops…as I find them mostly worthless since I must remove my pack to stow my poles).
The reputation of ULA as the maker of durable packs was one of the primary factors which led me to give the Ohm 2.0 a serious examination…because I am the most terrible thing ever devised for a backpack. Seriously…if I come back from a trip with a pack less than completely destroyed…it was probably only a day-trip.
The Ohm 2.0 is constructed of ULA’s 210 Robic…a near indestructible Dyneema material…on the back…sides…and top of the pack. 210 Robic is not the lightest material to construct a backpack from…but because of its remarkable durability I would actually increase its use on the pack if given the option. The front and top of the main compartment is constructed with uncoated 1.9 oz ripstop (which hinders my ability to punch holes through my bag quit a bit)…a Cordura bottom (which I will work diligently to wear away at by dragging it mercilessly)…and a lightweight stretchy mesh on the front pocket (which I have already patched with duct-tape).
The Ohm is a simple but versatile top-loading pack with drawstring closure and a top compression strap. The overall capacity of the pack is 64L…but the main compartment is only 34L…with the remaining storage distributed between two very spacious and easily accessible side-pockets…a large front mesh pocket…and two hip-belt pockets. Not one for a lot of complication…I find that the Ohm’s distribution of storage is well conceived…and is the perfect combination between organization and versatility.
The two large side pockets are probably one of my favorite features on the pack…made of ULA 210 Robic with elasticized closures they are basically indestructible…and capable of holding large Nalgeen bottles…a UL cook-set…fuel…snacks…and just about anything else you can imagine stuffing into them…these pockets are basically my glove-box + cup-holder when out on the trail!
The large front mesh pocket is made of a stretchy material that has the feel of pantyhose. For me personally a large front pocket is required of any pack I use…as it serves to keep my wet items like tarps away from drier items…but also makes opening my pack in the rain in search of raingear unnecessary. The front mesh pocket on the Ohm has a surprising amount of stretch and serves my needs well...but if given the option I would prefer the front pocket to be made of the same 210 Robic that the rest of the pack is made from…as I believe the delicate material used in the construction of the pocket is a poor compromise for the additional drying power it adds to gear I really do not mind being wet.
The two hip-belt pockets are not something I was particularly excited about before purchasing the pack…as I tend to find additional pockets and things unnecessary…but over time I have found myself growing ever fonder of these little guys. For one…the pockets keep things like my camera and snacks nearby…and while being large enough to be useful…I have not yet had any issues with the pockets getting caught on brush…or hindering my actions in anyway…the verdict at the moment is a positive one.
The ULA Ohm 2.0 is the latest version of ULAs mid-size original Ohm…but the primary difference between the two models is the addition of a beefier and more comfortable hip-belt. From the original version the Ohm 2.0 still makes use of ULA’s contoured shoulder and sternum straps…full-body compression system…and load-lifters…which in combination with the new larger hip-belt makes the Ohm 2.0 the most comfortable pack I have ever used.
The torso length is adjustable through a hook and loop adjustment where the lumbar support should be. Having a long torso I appreciate this added adjustability…but I question why the complete removal of all lumbar support? I think this is an easy enough fix (simply glue or hook and looping a piece of dense foam to the back of the pack)…but for me this is one of the biggest factors which ULA overlooked. With that said…the two-way tension control on the hip-belt allows the user to “seat” the hip-belt perfectly across the top of the iliac crest…a feature I will look for in every pack here out.
I do not find anything particularly unique about ULA’s upper harness system…but having the build of a wrestler I find the sternum strap…load-lifters…and contoured shape of the shoulder straps helpful in keeping the straps from rubbing the underside of my arms and sides of my neck…and to assist in keeping the pack centered against my back. The shoulder straps are a good width which distributes the weight of the pack nicely across the shoulders…and like any respectable brand the insides of the straps are constructed with 3D spacer mesh and a comfortable amount of foam. The sternum strap is fully adjustable…and the load-lifters are easily adjusted while wearing the pack.
The body of the pack is (almost) fully compressible via a length of low-stretch cord weaved along the sides of the pack. This is a simple and practical solution that helps keep everything snug and tight…but ULA failed to continue this system to the bottom of the pack. Probably to prevent the cord from interrupting the use of the large side pockets…but this could have been overcome by creating a channel for the cord to run through.
Overall I have not found this a significant drawback…as I use the pack more often than not near the maximum capacity of the bag…but the day-pack practicality of the bag would no doubt be significantly improved had the compression system been fully extended.
I have used the Ohm 2.0 for almost a year…comprising of 10 trips in total…with most trips being of the 2-4 day variety. Most recently I used it for a trip on the Adventure Trail near Corydon Indiana…and a 3 day trip through the Shawnee National Forrest with fellow trailspacers Eric + Jefferey + Vince. Though the Shawnee National Forrest trip was wet…it turned out to be rather dry compared to my aptly named Adventure Trail experience…where flashfloods turned my bivy into a water-bed…and supposedly dry creeks into raging torrents that required hours of bush-whacking downstream in search of safer crossings.
On a trip in the spring the Ohm 2.0 fought off continual attacks by rodents who were not at all discouraged by the fact that the pack was suspended in the air…and during a canoe trip in early summer the bag floated for about 3 seconds before plunging downwards during a river crossing in the Ozarks. Through all of the things this bag has seen in the last year…it still looks as good as the day I received it in the mail…the only damage being a small hole ripped in the front mesh crawling under a downed tree….that was easily repaired with a piece of duct-tape.
To be honest I loved the pack since the very first time I packed it full of gear and placed it on my shoulders…as I was immediately impressed with how well it carried…but over time this sentiment has only grown. The additional hip-belt pockets have added significant convenience…as I can take pictures on the go now…and yet I never feel as though the pack has too many pockets…or pockets of a useless size.
Furthermore…as I have learned to fine-tune the pack to my body…I hardly feel the pack when carrying weights of less than 20lbs (my typical pack weight with consumables). Though I picked the pack originally to be a mid-sized choice…it turns out that I find myself tempted to use the Ohm 2.0 for over-nighters (perhaps this winter it might just see such use)…and expanding its use for trips of longer duration…as the pack performed admirably on a seven day trip in the Ozarks (though I feel this might be near the edge of its capacity if you require food every day).
I would conclude by simply stating that the Ohm 2.0 is a great pack…that is probably well-suited for most people who keep their loads on the lighter side of things…and that it is impressive just how much work a person can squeeze out of this one pack!
This is now my favorite pack after a year of solid…

Price Paid: $210
This is now my favorite pack after a year of solid testing in all range of temperatures and trail conditions. A lightweight pack with a suspension frame that helps it carry loads up to 30 pounds comfortably. Except for full winter or over a week long trips, this pack can handle everything I need it to do.
- Frame pack (removable)
- Durable construction
- Giant pockets
- Comfortable and adjustable hip belt
- Adaptable removable options
- Venting at back
- Thin (bear canister tight)
- No top pocket (if you like that)
- Back mesh pocket not as durable
- Compression straps not one-pull
- Daypack compression shifts weight to bottom
The other reviews prior to mine do an excellent job of summarizing the qualities of this pack, and helped me choose the Ohm. I felt after a year that I would add to and support those reviews with my own. Hope it helps reinforce how good the ULA Ohm 2.0 really is.
I have now used the Ohm 2.0 for a full year on multiple trips of 2-4 nights. Conditions on the trips ranged from 10 to 85 degrees and included full sunny days, one trip with 3 days of rain, and everything in between. Overall, I have used the Ohm for about 20 nights (unfortunate circumstances this year prevented more trips).
My base weight (not including water, fuel, or food) ranged from 15 to 19 pounds. The lighter weights in spring/fall, and the heavier ones in winter. Total load in the pack ranged from 22 to 28 pounds.
Over half my walking was done on trails from the Appalachian Trail and other “groomed” trails, to wilderness trails that have seen little or no maintenance with heavy brush overlapping the trail and scraping along the pack (and me). The remainder of my miles were off trail bushwhacks through mostly open country, with some scrambles through rhododendron thickets and other obstacles.
I keep my pack in the tent for the most part, as I have a large solo tent (Lightheart Gear Solong 6). Overall treatment is with care, but abuse does occur on my off-trail ventures. I store it clean and dry inside the house between trips.
My prior packs have been a gradual descent down the weight chart and most recently I have been using a Gregory Z55 (since around 2006) due to its relatively low weight (3 lbs) balanced with extreme comfort and venting along my back.
The Ohm 2.0 is a 3,960 cubic inch (63 liter) pack that weighs right at 2 pounds. It is made of heavy duty 210 Robic and has a 1.2 ounce carbon fiber active suspension hoop that transfers weight to the hip belt. The capacity is divided out into several large pockets as well as the main compartment as follows (based on ULA’s description — note that the breakdown below doesn’t add up to the claimed 3,960 cubic inch volume — may be the mesh pocket stretch accounts for the rest):
- Main Body: 2,100 cu in
- Front Mesh Pocket: 500 cu in
- Side Pocket: 400 cu in each
- Ext. Collar: 500 cu in
- Hipbelt Pockets: 100 cu in
There are some bells and whistles on the Ohm, despite its low weight, that are easily removable as others have mentioned.
I kept the shock cord water bottle holders on the chest straps to try out and at first didn’t appreciate them, having used a clip to carry my “sipping” bottle for years. Once I had a few trips with practice removing and installing the bottle, I found I can do it easily without breaking stride and like how it stays put much better.
I immediately removed the hydration bladder pocket as I am not a fan of those. However, the small security pocket that comes attached to the pack uses the same clip system, so I rotated that to a more convenient spot (directly against my back) and now love the ease of access for my keys at the beginning and end of a trip (it doesn’t get opened EVER while on the trail).
I haven’t dabbled with removal of the carbon fiber frame pole, but did remove the back pad when using a trail chair, which can fit between your back and a bear canister making the back padding extraneous.
I also removed the hand loops as I use trekking poles. After these adjustments, my Ohm weighs in at 30 ounces. I could remove the other features, but am not really a gram counter and like the bottle holders and security stash pocket a lot.
Prior to choosing and using the Ohm 2.0, I had some initial reservations—primarily its sturdiness for off-trail travel and the lack of venting on my back. I have a high metabolism and tend to sweat when walking even in shorts and a t-shirt around freezing. The reason I have stuck with my Gregory Z55 for so long is the amazing venting on my back. The other excellent reviews of this pack, plus extensive research, resulted in my purchase in January 2016.
Ordering from ULA was easy and allowed customization of the torso length, hip belt, material color, and shoulder strap type. Shipping within the US was (and still is) free.
Despite its low weight, the Ohm 2.0 is a very comfortable pack. The hip belt has dual buckles that allow fine-tune adjustment of the angle the belt sits on your hips. For a relatively thin bony guy like me, this is a great feature. I have not experienced any hip pain, abrasion, or other issues while wearing the Ohm, and don’t have to adjust the belt at all during full days of hiking.
The shoulder straps are available in two styles—standard for most men, and S-curve for women and weight lifters or other men with larger chests. I found the Ohm to ride very well throughout the day, and needed minimal “shifting” of buckles and straps beyond my typical loosening and tightening of load lifters on steeper climbs and descents.
Loading the Ohm to its recommended maximum load of 30 pounds didn’t change the comfort level significantly for me, as discussed further below.
The torso length is adjustable by shifting the hip belt up or down. This is a simple attachment to the pack with some heavy duty velcro on both sides, a little tough to remove but firmly reattaches.
Back ventilation is an issue, as with many internal frame packs, and I did experience moisture along my back on days when it was hot enough for me to sweat. The pack dried out very quickly. I consider this the only real negative to the Ohm, for me, but similar to almost all other packs that I have tried. It is a small problem that is vastly overcome by the other benefits of the Ohm.
Durability & Weather Proofing
The Ohm is extremely durable given its light weight. It is constructed out of heavy duty 210 Robic fabric that has not torn or abraded despite my off-trail wanderings. On detailed inspection, I can’t find any threads loosening, or nicks.
The only weakness I think it has is the back netting pocket. This was mentioned in another review, but as it faces backward I have been lucky enough not to have any wear yet. I am fully confident that the Ohm 2.0 will last a long time and lots of trail and bushwhacking miles.
The Ohm is as weather proof as other packs I have owned. It will wet through during constant rain but kept my gear dry during shorter rains. I tend to use a trash compactor bag on the inside and rarely take a pack cover. The pack dries out really quickly when wet.
For me, it’s not all about liters/cubic inches of space in a pack, but how that space is arranged for use. I find the Ohm to be a perfect fit for my approach to backpacking and it balances the amount of inside/protected space and outer accessible space really well.
My sleeping bag (uncompressed in a trash compactor bag) sits nicely at the bottom, and fills out and pads the lumbar area. I have used both a light 30-degree Feathered Friends bag and a heavier/bulkier Marmot 15 degree bag and both carry well. The remainder of the inner bag is spacious enough (2100 cu in) to hold my clothes, camping gear, and food for up to 5 days.
The only minor drawback on space in the inner compartment is that a bear canister is a relatively tight fit. I am not saying it is difficult to get in, but that it leaves limited room around the edges to stuff additional gear. I can fit my first aid kit and various miscellaneous clothes (hat, wind shirt, gloves) that I want to keep in easy reach. I can fit my REI Trail Chair inside wrapped around a BV canister, and still slide it in and out easily. The relatively thin body of the Ohm creates this minor issue, but having that thin profile helps greatly when negotiating thicker trails and bush whacks.
The standout features of the Ohm, to me, are the side and belt pockets. Honestly, I can fit everything I need for an entire day into those pockets: phone/camera, navigation (map and compass), minor first aid, etc in one belt pocket; snacks for a day in the other; my cook kit and lunch in the massive side pocket, and water and filtration device in the other. This is really convenient especially in bad weather when you don’t really want to open up the main compartment until you get to camp.
It also has the now ever common back mesh pocket that is just stretchy enough to pile in my rain gear with a wet tent if needed. There are other packs with at least as much room in the mesh pocket, but they don’t come close in the other pockets. The mesh pocket has less stretch than some other packs, but holds everything I need especially on wet days.
The Ohm does not have a top pocket, which I don’t mind but may be a negative to others. The drawstring closure is easy to use, and except when absolutely packed to capacity can be rolled a bit to weather proof the top. Honestly, if you pack the Ohm to the point where it can’t be rolled closed, you are probably at or above the 30 pound comfort threshold. When my capacity was close, I simply clipped my ground sheet under the compression strap over the top of the pack.
As I mentioned, I have loaded the Ohm 2.0 with around 20 to 30 pounds total weight in a variety of conditions. If I concentrate, I can tell that it is getting near its maximum comfort ride near 30 pounds, but it still felt comfortable to me.
Just the other weekend, with a mid-20 lb load and wet gear adding significant weight, I almost felt that the Ohm was pushing me up a hill rather than dragging me back in the second half of a 17-mile day. The only way I am going back to the Z-55 is if I go over a week trip or maybe 4-5 days in winter with all that extra weight. Otherwise I am sticking with the Ohm.
The compression straps on the sides work relatively well, but don’t fully compress the entire pack unless you pull them in stages (not just from the top, but also half way up). As mentioned in another review, the compression system stops at the top of the large side pockets. I find that no issue for a full pack, especially with a sleeping bag in the bottom.
However, for use as a day pack from base camp, the lack of lower compression causes gear to shift to the bottom of the pack. It doesn’t affect the way it feels to me on the few trips I used it in this way, but may be an issue for folks who do that a lot.
After much consideration, I rated the Ohm 4.5 stars due to a few minor cons but none that you wouldn’t find in other packs of similar style. The only real deduction was for the lack of back ventilation for steam engines like me, but many similar packs suffer from this. The Ohm 2.0 is my go-to pack for most conditions now. It is the best built and lightest pack that keeps me in my “comfortably light” approach to backpacking.
I have dabbled with frame-less packs, but they are not an option for me after trying a couple. I am saving my 5 star rating for the perfect pack…but that may never happen!
Lightweight, yet plenty of room for gear. Designed…
Source: bought it new
Price Paid: $200
Lightweight, yet plenty of room for gear. Designed for comfort and durability. Unusual and useful ability to carry water bottles on shoulder straps. Exceptional hipbelt support and comfort.
- Very lightweight
- Durable materials
- Holds tons of gear
- Front pocket and hipbelt pockets susceptible to wear and snags
- Shoulder strap water bottle holders require some tuning to reliably hold bottles
The ULA Ohm 2.0 is a smaller pack in the ULA line, yet has the hipbelt of some of the larger models allowing it to carry substantial weights. The ULA hipbelts are top-of-the-line for comfort given their light weight.
The Ohm 2.0 has provided plenty of space for 4-day backpacks for me with room to spare. Its load-carry capacity allows me to lug enough water for Arizona trails.
See lots more details from the following video I filmed on a 4-day hike along the Tanner and Beamer trails in the Grand Canyon.
Very Light, functional, no-frills, up to 4-day pack…
Source: bought it new
Price Paid: $200
Very Light, functional, no-frills, up to 4-day pack (three days with bear canister). I highly recommend it, very comfortable with adjustable length and load lifters on top and belt. Clever bottle holder elastic loops on shoulder straps free up side pockets for more gear. My go-to pack.
- Can get in camo
- I'd add mesh pockets on the upper sides also
- I hope it holds up. I suspect ULA will back it up well.
It fits me just fine (5'10") with the adjustable back length, load lifters, and adequate padding on belt/shoulder makes a very comfortable (and light) pack ~1# 12 oz empty.
I've been on two short warm weather trips, Yosemite and Trinity Alps, and this thing is a breeze in every respect. I do seem to fill it up quickly, especially using a bear bottle (BV 450). I have used this with 25 and 27 (BV)#'s full wet weight on my 20$ scale. I can trim this but more cold weather gear or alot of water might be a stretch beyond a 4-5 day trip and that's fine with me.
Carries and adjusts on the go very well, organization is a bunch of zip lock bags in a bigger bag and it all works fine. The compression cords work well and and everything is easy to use, simple and well thought out.
I have had no durability problems and I highly recommend the pack. I replaced an Osprey Exos 46 to get the weight closer to my back and knock off a few more ounces which this does.
Hope this helps.
