The Osprey Atmos 65 AG Pack is a hiking pack for week-long and thru-hiking adventures into the backcountry. The Atmos 65 has stepped it up and added the AG, which means Anti-Gravity™ and it's all about the suspension, harness, and hipbelt. The LightWire™ frame, suspended mesh, and die cut foam all combine to wrap the body closely so you can hike on by without hardly realizing the weight upon your back. All that AND it is ventilated? Count me in. From there the pack is fully loaded with features you can't live without, compression straps, removable top lid, Stow-On-The-Go™ for those that only want to use their trekking poles half the time. The lower section separates your bag from everything else, with a direct-access zipper at the bottom.

Osprey Anti-Gravity

Osprey Anti-Gravity
Using Osprey's peripheral suspension design this lightweight, body contouring, three dimensional suspension literally allows the wearer to move as if they don’t have a pack on. Seamless suspended mesh from the shoulder blades to the lumbar and even into the hipbelt region disperses and balances the load like nothing ever has before.

Osprey Peripheral Frame

Osprey Peripheral Frame
Peripheral frame was a departure from the norm many years ago and it’s still the foundation of our gear hauling packs. A wire frame runs along the outside of the backpanel directly connecting the upper load lifters and the central core of the pack to the hipbelt to transition and spread the load. Allowing natural torsional movement, effective adjustable torsos, and different load range and backpanel builds makes this suspension design truly innovative.

Please note that the info provided above refers to the torso size each pack will fit, and NOT any dimensions of the pack. Below are some steps for how to get your torso length. You should probably have someone help take this measurement for you so it is accurate. And they might accidentally touch your butt.

• Start at the iliac crest, which is the top of the hipbones on the side of your body. These act like a shelf for supporting a pack hipbelt.
• From this level on your spine, measure to the C7 vertebrae, the knobby bone at the base of your neck when you put your head down.
• Make sure you keep your back as straight as possible while measuring.
• This torso measurement determines what size Osprey pack you should carry. Refer to the size charts above to find your ideal size.
• If you are in between sizes, it is ideal to try them both on before ordering.

• Measure around your hips at your iliac crest, NOT your waist.
• A properly fitted hipbelt rides centered over the hipbones and needs to be very snug.
• The padded portion should wrap well around your hips, leaving a gap of 3 to 6 inches between the tips of the both hip pads when securely tightened.
• Refer to the Hipbelts size chart above to help determine your ideal Osprey pack size, but again, your torso length is what should determine your pack size, NOT the hipbelt.

Rated 5 out of 5 by from Most comfortble pack I've ever had Bought this pack to use while Osprey is replacing my Aether 70. Very comfortable. Carried 40 lbs on 3 day cross country trip in Yosemite. No shoulder pain or lower back pain as with the Aether, but that pack was 6 years old. I hope the Atmos 65 AG is the one Osprey will replace my old pack with. Only problem is the belt pockets are tight and the zipper is impossible to pull closed with one hand while the pack is on. The material bunches up and doesn't allow the zipper to close. Had to have a companion hold the fabric while I pulled the zipper closed. Great design Osprey. The pack is as close to anti gravity as you can get outside of science fiction.

Rated 5 out of 5 by from Great quality you expect from Osprey This is my second pack by osprey and my first impressions is that this is anther high quality osprey product. Even on a hot and humid day in Texas this suspension systems keeps this pack from becoming overly hot. The mesh also seems to dry quickly durning breaks unlike other packs. The one thing that I would single out to improve on this pack is the location of the hydration hose port. My other osprey pack is a kode 42 and I love how the hydration hose routes through the shoulder strap because this keeps the hose from being annoying and rubbing my head and neck. If osprey could move the hydration hose away from the direct center of the pack the atmos would truly be the most comfortable pack on the market.

Rated 5 out of 5 by from All that Yo, believe the hype. Just got done with 30mi, 4/3 Day/nights on AT, snow, rain, sunshine, all of it. Yes it took about a day to really dial in the shoulder & hip belt with this crazy spiderweb AG design, but all packs take that, no worries. Once i got it situated it handled everything great. B/c of variable weather I was in & out of the pack all day, shedding layers, putting cover on/off, getting bladder in/out, etc: it was convenient & accessible. B/c of the way the booger hangs on ya like a monkey it's slightly difficult to get wrapped on ya when first shouldering it, like trying to crawl into a space suit, but really not a big deal - this is me knit-picking trying to be objective & give y'all a con here. Had it fully loaded for winter packing, prob ~ 40-45lbs first day, & it handled it great. If you're looking for a pack to regularly handle more than this then maybe she's not the girl for you, but my knees have sure appreciated me dropping from an 80L pack, so this is my "do-it-all" pack now. Once I ate some of my grub & didn't have my H2O bladder full it was about 35lbs & I felt like I could run like a dang cheetah. Biggest gig is the ventilation- even with layers & shell on it breathed better than I could have hoped. When my buddies dropped their traditionally built packs their backs were soaked, but I was drier than I've been with any other pack. & I usually sweat like a fat biker doing windsprints on the sun. Because of Osprey's overlapping sizes I'm on the cusp of M/L; I like this about Osprey, because people aren't cookie-cutters & their packs adapt to that. My point in saying this is although I'm an experienced hiker I appreciate throwing myself on the mercy of the gear shop and checking my pride at the door; by letting "Thad" or "Hunter" help me properly fit the pack to ME I gain the advantage of new gear designs that have evolved & I would otherwise be ignorant to. So if you have the option, try em on at the shop. I drank the Kool-aid, & it's sweet.

Rated 5 out of 5 by from Comfort and convenience This pack is amazing. Once you have it properly adjusted, you never even know it's there. Love that you can remove the brain. Compression straps mean your stuff stays put without interfering with your access to any of the pockets. More than enough room in this pack for everything you need. The adjustable torso length and fit on the fly hip belt gives the pack an edge over other packs out there. If your torso length is near the upper limit of a size, get the next size up for maximum comfort and adjustability. Bought this for my husband - I have the Aura, the women's version, and we both love our packs. Can't go wrong with Osprey.

Rated 5 out of 5 by from Most comfortable pack ever I recently purchased this pack for a short backpacking trip in Canyonlands National Park. In selecting a pack, my top priority was that it not compress the lateral cutaneous thigh nerve which passes near the upper front hip bone. On a previous extended trip with my older pack, compression of this nerve by the hipbelt caused a condition in my left thigh called meralgia paraesthetica, in which the skin becomes extremely numb and tingly. Apparently this is not uncommon among backpackers. Since permanent damage can result, I was afraid that my backpacking days might be over. However, with a load of about 35 lbs, the Atmos 65 gave me no problems in Canyonlands. The hipbelt distributed the load evenly around my hips and back without creating any uncomfortable pressure points. The pack had also been properly sized and adjusted by an Osprey representative, so that the hipbelt rested slightly higher than the point where the nerve passes. After a few decades of backpacking behind me, I feel like can now count on more years ahead. The only con about the pack is that the hipbelt pockets developed small holes from abrasion. When the pack is fully loaded and resting on the ground, the curvature of the belt causes these pockets to face downwards and rub against rocks, etc. This is definitely the most comfortable backpack I've ever used - very happy with it!

Rated 5 out of 5 by from CANNOT beat an Osprey Pack I have used this pack on two 5-day treks into the Snowmass Wilderness and the Sierra Nevada's. Could not be happier with the overall performance of this pack! Definitely a great pack for minimalist extended hikes (5-12 days) or a more comfort oriented/related trip (>5 days).

Rated 5 out of 5 by from Most comfortable pack I've used Tested over 4 days in Big Bend, this pack made hauling 50 lbs (had to bring in all water, rather than rely on filtering from springs) easy. There is a learning curve with the adjustments and it would be nice if there were side access to the compartment, but the numerous unconventional storage compartments and unparalleled "anti-gravity" suspension system made those points feel insignificant. The materials are tough, load balancing was quite simple and I expect this pack to last for several years of frequent use. Highly recommended!

Rated 5 out of 5 by from Incredible pack for multi-day use I purchased the Atmos 65 last year and used it on several mulit-day hikes during the winter months. At the time my pack load was around 45lbs but since I've reduced that weight significantly to 25lbs. This is an extremely comfortable pack even loaded heavy while traversing steep rocky terrain. The adjustability is incredible and if you select the right frame size I think you will be able to find the "sweet spot" with the shoulder straps and waist belt after the first few miles. There's enough room in the 65L for average hiking gear. It's not an ultra-light pack and isn't advertised as such. My scale has the pack weighing in at 4.6 lbs and with the removable "brain" you can save an additional 6.2 oz. The pocket separation is nice for organizing and the outer mesh pocket is great for rain gear. The water bladder pocket is inside the pack and I like the strap that holds your bladder in place at the top. The trekking pole loop and securing strap are handy and can be operated on the move. The waist belt zipper pockets can be slightly difficult to zip closed with one hand but not really that bad. Overall I can't imagine a much better pack unless you're trying to go ultra-light and want a pack that weighs a pound or so. I highly recommend it to the typical hiker who is looking for comfort on multi-day, long mileage hikes and wants plenty of room to pack average size gear.

So I'm 6ft 1in, and my sizing measurements are right between medium and large. Which pack size should I choose?

Asked by: CBfk
Hey there, Thanks for reaching out to us. There isn't really a hard answer when it comes to pack sizing. It just depends. It's best if you can try each size on and see which one fits and feels better. I'd be inclined to try the larger size, as you want your hips to carry the weight of the backpack, and have your shoulders stabilize the load. Hipbelts can be interchangeable, though. I hope this helps!

How large of a sleeping bag will the lower compartment handle? 15"L x 9"W, etc?

Asked by: BrianK
Hiya BrianK, thanks for your question! The compartment is roughly 15” x 13” x 7”. There is a removable divider separating the sleeping bag compartment from the main compartment that can be removed if you need more room. Hope this helps!

Does this pack come with a rain cover?

Asked by: KFox
Hey there, Sadly this pack does not come with a rain cover. You would have to purchase that separately.
