My pack fit on 07/28/2013 20:45:12 MDT Print View

Hi all. Great thread. I'd love feedback my Ohm 2.0 fit. I measured my torso at 18.5" (per the ULA website) and purchased a Medium Ohm (rated for 18" to 21"). I moved the adjustable hip belt towards the top, moving the length of the torso towards the shorter end of the range.

I'm planning to use this pack for the JMT. In the photo, I have it loaded with most of my planned weight of 28 lbs, including a WM Summerlite, an Exped Downmat UL7 (used as back padding), a BV500 with 7 days of food, and a Tarptent Notch. I'm missing some weight in my cooking equipment, clothing, water, and a few miscellaneous items. My Ohm comes in at 738 g / 26 oz, stripped of all features including the foam back panel.

FYI, I know ULA recommends against using the Ohm with a bear canister. I also have a Circuit and can't discern any positive difference between carrying the can compared to the Ohm when using the thick Dowmat for padding.

Thanks.

Edit: How do I orient the picture correctly? The photo was straight when I uploaded it...

Sean, it doesn't look too bad--certainly doable if that's where it's most comfortable for you. Personally, though, I would move it up an inch and a half or so.

Clearly, with the adjustable torso length, the pack fits. You might take it out for a few hikes and just play with where the hipbelt is positioned and see what is most comfortable for you.

Thanks, Clayton. I'll try moving the hip belt to the top of the adjustment, making the torso as short as possible.

I was a bit unsure when I bought since my 18.5" torso is close to the M (18" - 21") and the small (15" - 18").

Sean. IMHO you might want to at least try the next size up. You could go up to 1.5-2 inches longer. It is "OK" where it is at, but it is flirting (fractions of an inch) from being obviously too short.

But at the risk of repetition, the main thing is how it feels on you - with full weight and carried for a whole day. What do I know, you may have tough shoulders. Also, since you effectively have next to no frame, going longer may not help since it will probably eventually just sag lower.

Do yourself a favor, however. Since you are planning on walking 200+ miles carrying a decent amount of weight, at least try out one pack, loaded, and with a frame that can handle that weight well - just for comparison. For 0.5-1 lb more you may discover the weight really just disappears on you back.

Personally I wouldn't do a long trip with that kind of weight with that pack. It would be great for a weekend, especially without the bear can, but on the last part of the JMT you may be schlepping a lot of food. Respect the frame!

Lengthen or shorten torso? on 07/28/2013 23:19:23 MDT Print View

Mark, thanks for your comments. I may have misunderstood Clayton, but my next adjustment was to actually shorten, not lengthen the torso.

I understand your concern about the weaker suspension compared to the Circuit, but I've found the Ohm to be just as comfortable with my equipment (I was surprised the bear canister fits as well as it does).

Sorry--I wasn't clear enough. By "up" I meant in torso length, not up in the belt adjustment. In other words, I think you might do well with an extra 1.5" or so of torso length on the pack. I definitely wouldn't go any shorter than you have here.

Gotcha. Like the OP, I may have incorrectly assumed that I would be at the lower end of the torso range given my measurements.

"Gotcha. Like the OP, I may have incorrectly assumed that I would be at the lower end of the torso range given my measurements."

The pack is *clearly* at the lowest end of the torso length of the PACK that will be good for you, ergo YOU have a torso at the at the upper end what will work with that pack. It you had a framed pack I would be a bit more positive about it, but if you are going to be forced to carry a lot of the weight on your shoulders, and you are ok with that, then it is perfect.

Possibly go up one size, which is typically about 2 inches longer and see how it feels. Don't go shorter! Any shorter at all is a mistake. However, there may not be all that much you can do with no frame. If you could use a stiffer pad and pack it burrito style (like a ridgerest) then you might be able to reap the benefits of getting a good fit. Otherwise everything may sag a bit on your shoulders with close to 30 lbs on your back. If you are good with that then no problem. Trying this with an inflatable is a bit tricky, but I think I remember several threads on here over the years about doing just that. The volume required for support with an inflatable may seriously eat into your pack volume. An there may be some other issues.

Just try it out with a pack with more of a frame just to see for yourself. You could do this in a store at not cost. You could even bring all your gear in a box.

re: Ohm Frame on 07/28/2013 23:58:50 MDT Print View

Mark, the Ohm does have a frame, and it's rather robust, even for being so light. It's a pretty ingenious system that has worked for a lot of people. Given that, Sean I think you'll be fine from the point you're at in the picture and higher. Though, you are wearing the pack a bit high on your waist (not a bad thing--I prefer to do that too), so if you hope to adjust it by wearing it a bit lower later in the day, you would need more torso length to make that possible.

One of the great things about having built-in adjustments is how well you can tailor the fit. That just takes time. I'm about to do the fourth or so iteration for the shape of the stays on my HMG Porter, and with each minor adjustment, I learn a lot more about packs. For me, that's part of the fun.

Did it have more than that foam? It sounds like my older GoLite Jam which has exactly that. But is also sounds like even that is gone. Don;t get me wrong, I have and love packs like that, its just that I think there may be slight long-day comfort issue with over 20 lbs, at least for some people.

Re: Re: re: Ohm Frame on 07/29/2013 00:13:47 MDT Print View

Thanks, Mark and Clayton. I was a bit perplexed and measured my torso again and found that I'm at 20" using the ULA measurement. This makes sense now. At 5'8", I'm not sure if it makes sense for me to move up into the 21" - 24" size. That seems big.

Mark, the Ohm has a suspension system beyond the foam pad that I removed (assuming that the foam pad of the Ohm provides little or no suspension benefit).

Does This Pack Fit? on 07/29/2013 01:17:30 MDT Print View

Don't worry about how tall you are. I am 6 foot and have 19.5 inch torso. I may not be following this correctly, but currently you have the hip belt at the top of its range resulting in the shortest torso length possible?

Re: Re: Re: re: Ohm Frame on 07/29/2013 09:10:13 MDT Print View

Sean,

As we have been discussing in other recent threads, there can be a great variation and confusion over what you "proper" torso sizes is. You can't really measure it with a tape measure, thought using the standard method will give you a ballpark figure. This is because companies only give a recommended range, not actual measurements from the pack, because they define that range somewhat arbitrarily, and because people like to wear their packs slightly differently on their body. So just ignore what you think is the right length. You might want to look for a pack that when worn comfortably and loaded the strap attachment at the top are directly horizontal from the tops of your shoulders, and then measure the distance from the bottom or middle (remember which) of the belt to the place where the straps attach to the pack at the top. That is your actual "torso" length, and you can then use that to help find a pack in the future - by measuring yourself. Sorry for the repetition of this point, but it helped me tremendously in untangling the pack fitting knot. Recently I manage to order two packs online that fit me perfectly first time by figuring this out and asking for specific measurements.

Like Jason, I also have weird measurements. I'm short, but have the torso of someone over 6 feet. Basically a penguin. I also have found good-fitting packs with officially designated small, medium and large sizes.

Hi Sean,

Beating a dead horse but I'd agree with other responses in that you may find increasing the torso length (by lowering the hip belt) may be more comfortable for you once you creep over the 20lb mark. YMMV. Nice thing is that it only takes a minute to change it back if you find that the adjustment doesn’t work for you.

We have two ULA Ohm 2.0s in my household and I really love this ruck. I have the green version and my daughter has the purple blaze. After seeing her pack, I wish I would have ordered the purple blaze too.

It's nice to hear the bear canister is working for you with this ruck. I'm pondering a JMT hike in the next couple of years and would prefer to use the Ohm instead of purchasing a Circuit.

Happy trails.

Thanks everyone for the helpful feedback. I'll adjust the belt to the max torso length and repost a photo.

Yeah, and the sucky thing is since the Berikade is a bit wider you can't go by that. I found the Bearvault fit a small Exos ok, but to get the Berikade in felt like seams were about to burst. No good.

Hello. I moved the belt to the lowest setting, providing the longest torso adjustment on this pack size. The photo is a bit darker, but I hope you can still see where the belt attaches to my waist. Would love feedback and suggestions on this adjustment.

See below photo of the BV500 in my Ohm. My Circuit really isn't much bigger in terms of volume. I think ULA really promotes the Circuit as the bear can capable pack because of the extra back padding (mitigated by using the sleeping pad) and the beefier suspension via an aluminum stay (mitigated by keeping pack weight down).

FYI, I have my fingers crossed that the slightly wider Bearikade will fit as well as the BV500. I have one arriving next week.

Actually, that looks pretty good. I knew I was in trouble with my small Exos 48 when the bearvault just barely squeezed in. LOL

Anyway, one of the few benefits of not having a frame.

Pack looks a bit better now. Gonna go out on a limb and say it is probably as good as you are going to get, and to declare victory. With this style of pack you are going to have to put some of the weigh on your shoulders, and if it feels good to you then maybe switch to worrying about something else.

However I don't withdraw my advice to, just as an experiment and as a future reference, see how the same stuff feels in a pack with more backbone. Don't forget to fill the bear can with 7 day of food first!
