Description

The Osprey Atmos AG™ 50 features Osprey’s Anti-Gravity™ suspension system for quick drying ventilation and all-day comfort. This pack is well suited for weekend excursions or quick overnight forays when you are toting less than 40 pounds.

The secret to this pack is Osprey’s clever Anti-Gravity™ suspension system—a seamless backpanel composed of lightweight mesh extending from the top of the backpanel to the hipbelt that contours to the body to deliver outstanding fit and unrestricted movement. The Fit-on-the-Fly™ hipbelt and easily adjustable torso length optimizes comfort on the trail.

You can access your gear through the top of the pack or via a zippered front panel. The versatile floating top-lid is removable to shave weight but an integrated FlapJacket™ is always onboard to protect your gear from the elements. Final touches on this state-of-the-art pack include the Stow-on-the-Go™ trekking pole attachment system, and ice axe loops for winter ascents.

Comments about Osprey ATMOS AG™ 50:

I bought this backpack to find an optimum size and fit to go for overnight hikes while walking at a good speed to get a good workout. I've got the Aether 70l which is an overall great pack for multiple nights. For one night though a bit too big.
Below 40 turned out to be too minimalistic for me, so 50 seems just right and the suspention system is fantastic if you want to move fast and you become really hot.

What really is disappointing about this pack is the differences in features from 50 to 60 litres? Why would Osprey chose to do that? With a pack this size and load capacity you still have the same requirements for carrying an isolation sleeping pad when it's cold and you'd want the access to your stuff from the side zippers. I don't understand why you'd think customers using this bag with 50l have different needs than customers carrying 65l in this particular aspect.
I'm actually thinking about returning this pack just because of that.

      Comments about Osprey ATMOS AG™ 50:

      Disclaimer: I don't own this pack, but I did wear the 50L version loaded with 20 pounds around the REI store for a long time testing it out. It was a pretty comfortable pack and fit pretty well. I liked the amount of space, the pockets, and the flexibility it offered. I almost bought it. Why didn't I? Simply because it didn't have sleeping mat straps on the outside bottom. I have no idea why, and I found it very interesting that the 65L version, and most other Osprey packs do offer this, but for some reason they decided not to put any on the 50L version. Anyways, if that's not a big deal to you, go for it, I think you'll like the pack. For me, it was a deal-breaker, especially with 50L being on the smaller side for a long weekender type of pack where you don't want the sleeping mat taking up significant space. Please add sleeping mat straps!

        Comments about Osprey ATMOS AG™ 50:

        After reading some of the reviews on the Atmos AG 50 I felt I just had to add my comments. First, if you take your measurements and correctly adjust this pack, it will be the most comfortable pack you will ever own. It is true that there are no sleeping pad or sleeping bag loops on this pack. The sleeping bag is stowed in the lower zippered pocket of the pack. This is how the pack was designed. I stuff a military issue gore tex mms bivy cover as well as my down sleeping pad in this pocket with no problem. If you must have the lower loops then you need to buy the Atmos AG 65 that has the lower straps. The pack is more comfortable with everything in the pack not hanging on the outside. I am a hammock camper so this pack is great for all my gear including an inflatable sleeping pad folded up inside the pack. The internal hydration pocket fits my 3L Osprey Hydraulics bladder great. I use the quick connect kit that allows me to fill the bladder without having to remove it from the pack. The zipper pockets on the waistband are great for things you need to get to easily i.e. Cell phone, multi tool, etc. The two external water bottle pockets are easily accessible while hiking also.
        The antigravity mesh makes this pack the coolest and most comfortable pack you will ever own.

        Comments about Osprey ATMOS AG™ 50:

        Looks great. Has all the bells and whistles minus a rain cover. A bit hefty. I am slim so when I adjusted the hip belt It was as far in as it could and just felt like it needed to be tighter. The hip belt is so bulky that when walking up stairs for example it wouldn't allow me to take a big step up without it restricting my forward leg motion. the crease in the hip belt were the black fabric meets the grey mesh was digging into my hip the whole 45 mile hike. It was not a comfortable pack that I was hoping for.

        Great bag but could be better

        • Light Loads

        Comments about Osprey ATMOS AG™ 50:

        This is my very first Osprey and I wanted to like it a lot but after several trips, there were some issues that I couldn't live with. I'm 5'5" athletic built (Triathlete, Wrestler, MMA, etc), ended up getting a small which is only 47L.
        Pros: Light weight, tough material, cool style, overall great quality bag.
        Cons: No sleeping bag strap(they should explain why), the hip straps tends to flex in all the time, you have to really work at prying it open. Anti Gravity hip area kept pushing my pants down.

        If you're a minimalist this bag would be great. Having 2 or 3liters more would've been perfect for my size and what I needed to bring. 47L really forces you to think and adjust your gears. I had to re-buy several items to meet this bag's request. If you need more volume, get the Atmos 65, that has more room and two sleeping pad straps in front of the sleeping bag compartment. Or get the Aether 60, that too has pad straps. Or you can jerry rig it like me and use the ice pick loop and attach strap buckles to it.

        I love this pack . I have had it almost a year and it was well worth the money. One thing that I like that many packs do not have is the ventilation on your back. it keeps you cool in the simmer.
