Osprey Packs

Atmos AG 50L Backpack

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).

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.

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.

Incredible pack minus the weight

Absolutely love this pack. It's the most comfortable I've used, but it's quite heavy. You trade weight for overall comfort when loaded up. If the majority of your kit is relatively light I would highly recommend this pack.
