Great! …. Apart From
The waist pocket zips do not close found them so frustrating - impossible to operate - the pockets need moving closer to the centre of the waist or the zips need charging.

Overall Good
On firt trip with it, the rubberised meshing has started to come away. Comfort is good, however, the plastic clips to adjust the height of the straps digs into my shoulder blades, which was sore after a while. They could be better off lower down on the backpack, will look at moving them myself for next trip. Lots of space for everything I need for a 3 to 5 day trip. The on the fly walking pole storage just gets in the way, I ended up storing poles in the ice axe storage part.

I Most Like The Ease
[This review was collected as part of a promotion.] I most like the ease of adjusting the pack vs the the old model.

Only About 20 Miles On
[This review was collected as part of a promotion.] Only about 20 miles on this new pack but thrilled so far! This was a replacement for my 20-year-old pack. I was embarrassed to send in my old pack for repair and, surprisingly, Osprey sent me a replacement. So grateful for their policy and standing behind my original purchase so long ago. Really enjoying some of the improvements of the feature set of the new Atmos. One negative point - I am struggling to zip the pouches on the hip belt while wearing the pack. Should work easily one-handed but it does not work well. Encountered another backpacker with the same model that said he was having the same problem. His pack and mine were both brand new. Hoping it improves with use and break-in. Really pumped on the pack overall. Super comfortable even when overloaded (wanted to be < 30 lbs but carried 38 lbs when full on Day 1).

Atmos Ag50
Great back pack comfortable and easy to adjust to fit perfectly. My only complaint with osprey bags is would prefer a simple loop for a carabiner in each top pocket. I really don’t like the cheap pastiche key clip. Minor point but a simple loop to attach a small dry bag or carabiner would stop things falling out.

Do Not Buy This Pack Unless You Try It On First. It's Way Too Big
This back is way too big. The waist straps are too big and don't tighten enough. I am 5.8 and weigh 150 pounds. I went on a trip and came back bleeding from my hip bones.

The Atmos Ag 50/65 Is
[This review was collected as part of a promotion.] The atmos ag 50/65 is THE BEST backpacking pack out there hands down. I personally use the 50 L and it is the perfect size for 1-3 night trips. It is extremely comfortable with around 30lbs of gear. I love the sleeping bag pocket on the bottom of the pack, absolute necessity and only a feature on the atmos AG NOT the atmos LT. The removable lid is also a welcome feature when you’re trying to go lightweight.

One Of The Best
[This review was collected as part of a promotion.] This is one of the most critical pieces of gear from my 2023 Appalachian Trail thru-hike. Before I had picked any of my other gear, I knew my pack would be an Osprey. It didn't take much research to settle on the Atmos 50. This thing is a beast and could handle anything I threw at it or in it during my hike. The best feature is the one everybody already knows well: the airspace and ergonomic curvature that perfectly forms to your back. Furthermore, this distributes weight very efficiently, allowing your hips to bear more of the burden and relieve your shoulders. Other features I love include the waist pouches where I stored quick access items like my multi-tool and hand sanitizer, the included rain fly for quick rain protection, and the angular water bottle holders on each side where I had quick and convenient access to my one liter Smartwater bottles. I even made regular use of the two pockets in the brain portion. The interior dimensions are sufficient to fit a bear vault of the largest size turned sideways. There are straps on the bottom end of the pack that frequently held my tent, though you could also extend the top straps for the brain and store your tent under there too. The shoulder straps are thick and comfortable. I was able to attach a phone pouch on one and regularly attached my umbrella to the other. The materials are rugged. Despite all the use and abuse, scraping on trees and rocks, repetitive motion abrasion, weather exposure, and slinging around, the pack held up well without failure for 2,000 miles. There are probably adjustments I could have made to reduce weight, as this comes in at 4.2 lb. This while most thru-hiking packs in the ultralight category are less than half of that. With Osprey you're getting two extra pounds of comfort, in a sense. Alternatively, they do have the Exos 58 that weighs less. Also, regarding sizing, I think osprey could improve by separating them out into four: S, M, L, and XL. Other lesser known UL brands do this, so I would think osprey could handle it. This is my only real "complaint". All around, Osprey is, in my book, the best backpack maker in existence.

Everything I Need And Want
[This review was collected as part of a promotion.] The only problem I've encountered was getting the hip belt right. I'm a skinny guy with bony hips so it took a bit to get the hip belt right. But the pack is super customizable so I eventually figured out the setup. I got this bag to downsize/upgrade from my old 70L(?) pack. Its been perfect for 4 days of backpacking or quick car camping as well. I was initially worried about having less pockets than my old pack, but that turned out to be a non issue. Great bag!

Excellent Overall
[This review was collected as part of a promotion.] Great size for a variety of adventures. Super well built, as you’d expect from Osprey. Very comfortable, and the air flow is outstanding. You might consider the 65L if you’re an overpacker, but I think the 50L is great to help keep weight down.

Great Features, Great Color!
[This review was collected as part of a promotion.] I bought this backpack as a gift for my husband, who is a multi-day hiker. I am not a hiker myself, so I was a little nervous about the purchase, but Osprey made it easy take the chance. And he loves it! Its very well ventilated, light weight, and has great access for things you need to reach for regularly. The hip straps are molded in a "hugging" position, so it makes the load feel more securely positioned over his hips and takes pressure off his lower back. And I love the color, he looks great in this shade of green. We are very happy with the purchase!

New Pack
Just picked it up, packs well and comfortable. Just curious why there are loops for ice axe but no attachment points for them?
