Not too small...not too large...the UL Goldie-Locks of packs!


  • Comfort
  • Control
  • Design


  • Lumbar
  • 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.


In Use

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!


Nice review, Joseph. I spoke with Chris at ULA yesterday. We discussed my build, torso length, waist size, chest size, inseam, and he made great recommendations for me. He is shipping me 2 packs- one with the Med belt and one with a Large belt. Also, he is sending me one of each type of shoulder straps. He told me to try the combination that fits me best and send the other one back. He is adding a longer sternum strap as well. Needless to say, I am VERY IMPRESSED with their service so far. My pack(s) should be here in a couple of days, as they are already shipped! Can't wait to get them in and fine tune the packs into the best combination that fits me best. Will update later. Thanks again, as your review reinforced my decision to buy this pack.

Backpackerguy...ULA's service is top-notch...and you will only be more impressed with their pack...the Ohm 2.0 is far and away the best pack I have ever owned...it is clear that people who love backpacking have a hand in the design of ULA packs. To be honest...I am surprised that their packs are as reasonably priced as they are...looking forward to reading your report!

Hi Joseph, I've been considering this pack for a while now. I currently have a GoLite Jam 50, which has turned out to be the worst pack, by far, I have ever owned. I would review it but people seem to love it, rating it highly? I honestly don't get it. The frame sheet is useless and the pack sags 100% of the time. I also have a friend here in Tucson whom is one of the gear testers at backpackgeartest whom reviewed this Ohm pack. Both of you like it. One of the problems I have here in southern, AZ is that I NEED to carry at least 6L of H2O. My gear alone weighs quite a bit less than 30 lbs. but once I add the H2O and food I'm closer to 40 or 45 lbs. How is this pack with close to 45lbs of weight in it? Also, I simply do not care for side pockets on a pack because I find that I cannot swing my arms efficiently causing my natural gait to suffer. Do you have any issues with your arms banging into the side pockets when they're full? Good review, Joseph!!

Thanks David...glad to see some of these older reviews are still getting looked at:-) I also hear you about water David...even here where I live (it is often wet) water can be a big issue at times (70 miles without a reliable water-source is a big deal). To be honest I have never carried over 30lbs in the pack...so I cannot say with any 100% honesty that the pack could do it...but what I can say is the suspension on the pack is a full-suspension in every meaning of the word. In fact...in most things this suspension is equal to or better than that of bags designed to carry more weight. However...if I was to carry around 40lbs with this pack (shudder)...I would probably replace the stays in the pack with something stiffer but still relatively light...this should allow the bag to transfer more weight to the hips. Not sure of what I would use...but I am confident I could find something appropriate at the hardware store. After the stays I really do not see why the pack could not handle a heavier carrying load.

Lightweight, yet plenty of room for gear. Designed…

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
  • Comfort
  • 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 nice video. Thanks for the review!

Very Light, functional, no-frills, up to 4-day pack…

Rating: rated 5 of 5 stars

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.


  • Lightweight
  • Comfortable
  • 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.


Thanks for the reviews, 1kdude. I'd love to see a picture of this pack filled up.
