Overall I am fairly happy with this pack. However, there are virtually no attachment points to lash anything to the sides of the pack. This is a major flaw, IMO.

There's always a few niggles from reviews about the bag. Minor, no pack is ever, ever going to satisfy everyone. The big thing should be, how does this pack feel after several hours in the mountains. I had a Gregory z55, never really unhappy with it, but never really was awed by it. 2 tramps ( sorry, need to stick to new Zealand vocabulary) in my beautiful country, not heavily loaded, maybe about 15kgs, and I'm just downright in love with it. The pre molded hip belt feels odd when you first put it on, but it just kind of snaps around your body and hugs you like your best buddy. As soon as I put it on, it just felt like it was molded for my body personally by some kind designer. Sometimes, i just kind of forgot I had it on. Yep, everyone has a different body shape, but for me, the design of it just means it kind of melts into your body and it's a joy to walk with. Sure, maybe you want the top flap removable, maybe the hip pocket zips are a little tight, get over it and remember why you are out in the mountains, to forget our stupid little western complaints and enjoy our wilderness. Thanks Osprey, it just makes an older body enjoy his time in the mountains a little more.

This is a great bag for anything from weekend to a week out on trail. I have used it on 4 separate 5 day hikes now and its amazing! I bough this to replace my aether 70 which was just too much pack for me. The only thing i miss about that back was the top lid acting as a lumbar pack. That was perfect for holding my water, an extra layer, and my medkit on day hikes. The only things i wish the atmos had was the lumbar pack option (or the new aether daypack toplid) and the hip belt zippers to be revamped. My old bag had no issues with one handed use, the atmos seems to jam up most times. Neither of these are deal breakers, but they dont allow for 5 stars.

The problem with this backpack, is I don't think the person that designed it planned on ever wearing it. I read on a review site called Outdoor Gear Lab that this new version of the Atmos 50 had more padding in the shoulder straps at certain areas (true) and that the base area of the waist belt had been widened so the bag would fit a wider range of folks (I think this statement is false). I am not a giant guy, but like the previous version, the base doesn't fit all that well. It needs to be wider. Another reviewer here on the Osprey site mentioned the zippers on the waist belt taking two hands to zip and unzip. Totally true. A cheaper Mystery Ranch bag has zippers that can be opened and closed one-handed, yet this more expensive bag does not have that same attention to detail or quality. Why the cheap zippers? Why no rain cover? Why the negative online reviews about the warranty not being honored past one repair, unlike the old Review Outdoor Gear video(s) online suggests? The way the waist belt folds in while not on your body works well for shipping, would work better if the bag fit more like the Aether. I have gotten many Baltoro bag waist belts damaged on arrival due to how the belt doesn't fold in, so I prefer Ospreys. If you want a wider base at the hip belt area and a some-what better overall backpack, I would suggest the Aether. I am also not happy with any of the colors. Maybe why Osprey markets mainly to women on Instagram. Outdoor Gear Review videos claim the waist belt pockets are almost unusable. I don't agree. You're just not going to carry your huge phone in the pockets. I think Osprey needs to come up with something similar to a Gregory Baltoro or Arc'teryx Altra / Bora waist belt design. I need a comfortable backpack I can carry all day, every day. Actually, for all these suggestions, I could use a sponsorship.

I've used one of these for a few years, as it's become one of the more popular all around packs out on the trails. The suspension is nice and really feels like it's hugging your back. I appreciate the fully padded hip belt, which hasn't been skimped down to some lightly padded webbing like on the Exos and Levity. I also really like the clean design, with minimal stitching on the outside of the pack exposed to wear. However it's not perfect and I think a few improvements need to be made before I can recommend or would buy another. First - the built-in 'FlapJacket' on top is super annoying. I never hike with a top lid, and dislike having to also undo (and redo) the buckles every time I need to get into the pack. It should be a fully removable option instead. Second, I'd much prefer to save a little weight than have the sleeping bag compartment opening on the bottom of the pack. The fact that it has such a tight fitting zipper flap and no zipper pulls makes it more of a pain to get in and out of than it's worth. This is a recurring problem on other Osprey packs I own. Lastly, zipping up the hip belt pockets is a two-handed affair. Not sure what can be done about it, they're really nice sized and useful pockets, but the zips won't shut with one tug, you have to use your other hand to reach across and hold the back of it while you zip it up.
