Enjoy the journey.

Backpacking isn't the most enjoyable thing when all you can think about is getting to your campsite and ditching your pack. The newly redesigned Osprey Atmos AG 65 Backpack features Osprey's Anti-Gravity Suspension system, so you can take your mind off your aching back and enjoy the views while you hike. The system places a continuous panel of lightweight mesh from the top of the back to the hips for a seamless design that automatically contours to your back. Not only does this make the pack more comfortable, but it increases your range of movement. On top of that, the Atmos AG has an adjustable harness system, so you can dial in the perfect fit for your individual torso size.

Built for multi-day backpacking trips, the Atmos AG 65 Backpack has everything you'd expect from serious mountain pack. An internal hydration sleeve lets you fit the pack with your favorite hydration system. A top access point makes for easy packing, while the floating lid adjusts to make room for extra gear on big trips. The lid can also be removed to save weight for those hard summit pushes. Two front panel pockets stash extra layers, maps, and a few snacks, while multiple gear loops allow you attach your trekking poles and ice axe.

Favorite Osprey pack

  • Familiarity: I've put it through the wringer

This is my favorite osprey pack I have bought, and I have bought many. Great size, while super lightweight. The great suspension got me through a week of backpacking in Norway with a heavy load. Great organizational pockets, I fit everything I needed without feeling like it was overfilled or off balance. I wish it had come with a rain cover incorporated but have now gotten one so all is well!

New Atmos, Same Love

  • Familiarity: I've used it several times

I had an older Atmos model a few years ago and recently upgraded. Took it out for a long weekend in Michigan and absolutely loved it! More pockets, zippers, and straps than I knew what do do with, but it never seemed cumbersome.

The "Anti-Gravity" suspension system is a godsend--I was able to carry everything including 2 gallons of water without feeling any excessive burden. I was able to walk, climb, and even run without any jostling or struggle. The ventilation is the best I've ever seen and even kept my hydration pack cool.

It's obvious that someone spent a lot of time designing this bag well. Numerous pockets are easily accessible while hiking--pockets on the hips, the lid, sides, all over the place. The pack itself is roomy and can fit a ton. I had everything packed before I even realized the storage space at the bottom for my sleeping bag.

Osprey clearly knows what they're doing and how to make a bag worth recommending.

All you need is love and the atmos AG !!

I have had a few backpacks on my back the atmos Ag does not count as one, the way this backpack works is that everything you put in it is teleported to a temporary storage room on an osprey secret facility, then when the mesh touches your back the 158 silenced micro propellers turn on automatically carring not only the weight of the teleporter inside the bag but also 2% of your body weight, lulz yea I don't know how the built this one but it goes perfect with your anatomy muy gravity center seems to be in perfect balance with the distribution of the pack and the mesh on the back keeps the nice air flowing keeping you dry this is really the best backpack ii have ever seen a true new generation

All you need is love and the atmos AG !!

Are you sure the top lid works as a "fanny pack."

Best Answer Responded on

I am double checking with our Osprey Rep but, I am pretty sure there is a waist belt to be used as a fanny pack. If I hear differently I will update this answer and follow up via email.

Feel free to hit me up at or 801-736-6398.

Just heard back from rep, I was initially wrong. It does not have a fanny pack option, we will get the site updated.

Thanks for taking that Bill. Looks like the site was updated already!

Light and comfortable

  • Familiarity: I've put it through the wringer

All around great pack. It has a bottom zipper to put your sleeping bag in and access it easily. Comfortable all day and easy to adjust while hiking. Holds your trekking poles on the front if you need to use your hands to climb. Only complaint is small side pockets that won't hold a Nalgene size water bottle

Responded on

Hey there - Leta from Osprey here.

Really good feedback about the side bottle pocket. Always ways in which we can improve! I will pass it on!

Solid backpacking pack

  • Familiarity: I've put it through the wringer

This is an awesome pack that I got for my partner-- simultaneously lightweight, and yet can hold all your gear for an epic weekend of exploration! He can easily fit a 3 liter hydration bag, sleeping bag, sleeping pad, clothes, tent, cooking equipment, food, water filter, and seemingly endless amounts of other accessories (ie: the all important boxed wine!) inside/ strapped outside, mainly using it for 3-4 day backpacking trips. The packable rain cover is AWESOME for use in the northwest (where even though it's summer, rain is never too far away...), but it stashes out of the way easily if needed. Huge selling point was the lightweight mesh that allows for air to flow to your back while you have the pack on and are hiking (while it doesn't eliminate "swamp back", it definitely helps). Super solid bag that has lasted us 3 summers and countless adventures!

Wish I had mine. Was set to SHIP JUNE 5th, and did not.

Most comfortable Osprey pack I have.

Responded on

Hey Parker - Leta with Osprey here. So psyched about this pack and glad you love it! Thank you!


Do you have any idea when you'll get backordered packs out to people?

Responded on

On my order it says arrive by may 22nd. So pretty soon I guess. Now with the summer sale, it's only 205$, worth every $$ !!
Update: It's been almost 4 weeks now but no ETA yet for the shipment.

worth its (packed) weight in gold

  • Familiarity: I gave it as a gift but have feedback to share

I bought this as a gift after my boyfriend got pack-jealous of my women's Aura AG. The AG system is beyond amazing to the point that it's hard to put in words--you just have to try it; it is so proficient at ensuring the weight rides where it should on the hips without pulling on the shoulders at all. He opted for the 65 since it has the extra 2 side-zip pockets and the pad straps. He wanted the option to be able to pad and pack his camera and lenses separate of the rest of the pack. the stretch side pocket and gear loops hold a tripod well and the side-zip pockets also hold the tent poles perfectly. You can't really ask for better tech than this pack is packing.

The picture of the graphite grey shows at 50L size. Can you confirm it is 65L?

Responded on

Hey Rkb,

This WILL be the 65L size. We'll get that image fixed.

Hit me up if you have any questions or would like to place an order!


Responded on

I tried to order this on back order with the free hydration pack. The order would not proceed and cited no inventory. Please fix your system. Why have customers take the time to set up a back order when the order will not complete?

One Pack to Rule Them All...

  • Familiarity: I've used it once or twice and have initial impressions

This new suspension/ventilation system deemed as "Anti-Gravity" is a game changer! I don't know if some kind of sorcery is involved or what, but it is MAGICAL! I mainly bought this for an upcoming trip to Central America, but I can't wait to get it out on the trails. The anti-gravity mesh molds to my back like a glove. It literally is one continuous piece from top to bottom...even to extends out on the waist straps. I would not be surprised if this becomes standard on all Osprey's literally that amazing! I can't say enough about this pack. Great job Osprey!

Great Pack

  • Familiarity: I've put it through the wringer

Bought this for a trip on the Appalachian Trail this coming summer and using it just for over a month to get acquainted, I can't describe how good of a pack it is. The waist straps work so well there is little to no strain on the shoulders when properly adjusted. Having a previous back injury, I couldn't have wished for a better pack. If there's one thing that I can't put into words, it would be how well weight is distributed. Better than any other pack/ruck I've used. Two thumbs up.<br /><br />UPDATE:<br />This pack has been put through the wringer. On one occasion, I was hiking a narrow section of the Sheltowee trace when my feet were knocked out from under me and I took a spill off a cliff. The pack survived, completely in tact and managed to keep all the goodies inside in tact as well. It's also very comfortable to wear, be it a few miles or a grueling multi-day hike. Favorite pack I've owed out of North Face, Osprey and other assorted ones. This one will be in it for the long haul.

Will you be getting anymore of the graphite grey in a size medium?

Responded on

Hey Sean,
Looks like we just got these back on the site and currently have them available to place a backorder for. Hopefully we should be seeing them back instock within about 2 weeks. Get in line soon as I suspect this awesome pack will go quick the moment they get back in stock. Let us know if you have any other questions.

suspension does transfer weight on hip

shoulder has freedom now, amazing.
pro: suspension is great, hip belt is air flown, con: elastic tie need enhance, need more places to hang gears

Responded on

Great review! Gives me much more confidence in buying this pack despite the fact that it is so new. Thanks!

Responded on

This is one of the best gear reviews I have seen in a long time. Thanks for taking the time to do it.
