Load it up and Lug it out

Fit:
True to size

I've used this backpack for all my backpacking trips this summer, and I honestly don't want to use another pack. A lot of thought was put into this pack from people who've done a ton of backpacking over the years, and it shows. The top-membrane, the compression straps, the sleeping pad storage, the trekking pole storage, the hydration bladder storage. Everything is where it needs to be. But, I must talk about the most import part of this backpack, and that's the AntiGravity suspension. It's insanely comfortable, and it makes my body feel heavier, instead of just my shoulders feel heavier, if that makes any physical sense. I do feel because of this suspension, I can actually carry even more weight than I normally could, not that I recommend that you do. I have only two minor complaints though. The belt pouches are impossible to zip back up. I always had to ask someone else to zip them up for me. Same with the water bottle storage. You can get your water bottle out by yourself, but someone else is going to have to put it back in. Very minor issues, and overall, I really can't recommend any other backpack for backpacking than this one. The Osprey Atmos AG has everything you need, they way you need it, even if you didn't know you needed it, and will allow you to become a mule if you need to without the process being agonizing.

I'm not a total ultra light fanboy, though I do try to lessen the load with quality, UL products whenever I can. Comfort and durability remain the most important aspects to me. So I was a little concerned with this pack since it's not the lightest - but dang, it carries that way! The hip belt is practically spring loaded and suctions around you before you even tighten the straps, making a pretty heavy back feel seamlessly suckled to your back. I love the Rigby Red color and got tons of compliments on it :) The sleeping compartment easily fits my Marmot Helium down bag, sleeping clothes, and my inflatable pillow and inflatable sleep pad. What I also like about the sleeping compartment is that, looking down at the top of it when you're looking into the empty bag, there are small openings on either side leading from the main compartment into the sleeping hold, and this is a perfect place to slot your tent poles through. I prefer to carry my tent inside my pack rather than strapping it to the outside, though of course you can do that as well. The only con, and this is minor, but I'm surprised it wasn't mentioned more in the reviews - the hip belt is HUUUUGE. Like, crazy long. I'm a lean, thin-framed dude, and the excess straps after tightening the belt are like two feet long. I plan to cut them and then solder the ends with a lighter as it just seems silly. No clue why Osprey made them so long, but it is what it is. You'll enjoy this pack.

I bought this pack without the benefit of a fitting in a shop — the pandemic closed shops —  and being relatively new to this I paid a small price. After a day with some pain between the shoulder blades, I figured out the antigravity adjustment at it was bliss after that. The pack felt like a part of me, and every compartment was maxed. I am disappointed that I damaged it on its first outing — a slice in the back from what could only have been a broken pine branch or limb that I crawled under. Given the other reviews I've read about the bag's durability, that surprised me. I still recommend it. I also recommend the rain cover. I went a size up, and I'm glad I did.

I absolutely love this pack as it is the most comfortable pack I have ever worn. Great packing and space allows for you to bring everything you could need! Have been out on tons of trips and it has yet to fail me in any way. I even took this out on an overnight winter trip with all my ski touring stuff strapped to it so around 60 lbs and it was still plenty comfortable. I have recommended this pack to two of my friends and they love it as well. Wouldn't dream of purchasing a different pack!

This bag awe man this bag! Man, this is the greatest backpacking bag you will ever put on your back! At first, I treated it like a baby because of the price but then I slid down a rockslide in the grand canyon...on this bag,(accident) and it survived!! And at the end of the day, this bag makes a great backrest. I had about 35lbs and I would forget it was on. WARNING if you get this bag you will be carrying your stuff and your friend’s stuff(but you won’t care because the bag is awesome)

I bought this pack for my son. I have the model a year or two older. This one improves the storage, pockets, straps and closures and access from the top. Cant wait for him to go off to college so I can 'borrow' it.

Atmos AG 65 - a great backpack

Familiarity:

I saw good reviews about the atmos AG 65 and bought one from backcountry. I could not be happier with it. I hiked 30 miles in the smoky mountains and the AG 65 was really comfortable to carry.

Next Level Pack

Familiarity:
I've used it several times

This pack has some amazing features that will help you go farther and faster. The anti-gravity system works amazingly, it provides the perfect ratio of weight distribution from the hips to the shoulders. Compared to my old 65 L pack that I got on Amazon years ago, the Atmos feels like a feather. The adjustable back panel, shoulder straps, and hip belt make it easy to get the perfect fit. There are a lot of nifty pocket options making organization a charm. My 40 degree down sleeping bag easily fits in the sleeping bag compartment, which is removable for some organization purposes. I use this pack for backpacking. I can easily fit my sleeping bag, tent, hammock, clothing and more into this bag. I also use it for my climbing adventures. My 70m rope, harness, quickdraws, shoes, helmet, hammock, extra layers, and more all fit easily. I am 6'0, 175 and a got the medium size frame which fits me well. I would highly recommend this pack.

Best pack I have tried yet.

Familiarity:
I've put it through the wringer

I needed something between my 35L Lowe Alpine and 85L Gregory. I had tried the previous version of the Atmos and found it did not handle heavy loads well over 35lbs or so. The new model went on sale so I jumped all over it and picked it up due to positive reviews on how well it carries heavy weight. Simple answer is that this backpack is a total dreamboat in every way. Looks good in gray, perfect features, and unbelievably comfortable suspension. As a previous reviewer pointed out, this pack works great for skinny guys with no hips. I'm really tall and have around a 33 inch waist. The medium fits my waist perfectly and I am just barely inside the back length with it fully extended up for the shoulder straps. Even without the excellent suspension, this pack is still tops in terms of features. When carrying heavy loads, it's not fun to have to stop and take the pack off in order to get an item. My Gregory pack can handle 60 pounds no problem, but it has the most pathetic hip and side pockets ever. The Atmos seems to be designed by someone who actually likes to access items without even stopping or taking off the pack. The two hip pockets are plenty big for snacks, tools, phone, etc. The side pockets are easy to access and stuff up to a 32 ounce water bottle in each. Compared to the older version, I think the hip belt holds tighter and the shoulder straps seem to be much thicker and more comfortable. I would say the new version probably holds weight better by about 10 pounds. So 45 pounds in the new version feels like 35 pounds did in the old one. The top lid is actually very useful compared to my other packs. First, it's pretty huge once it's stuffed full. I can fit my entire camera bag into it, which contains a Sony interchangeable lens camera and two lenses. On top of that, the access is from the shoulder side of the pack, so the lid is easy to access when the pack is leaning against a tree or on the ground with the zippers facing up. Weight limit? Well, it is a 65L bag, so unless you're carrying gold bars, it's hard to fit enough into there to hit uber heavy weights. I tested it out with 5 gallons of water in the pack, and weighed around 45 lbs overall. Opsrey lists the Atmos as being able to carry up to 50 lbs. I think this is totally possible to hit 50 for short distances. Say, for example, you are carrying 40 lbs, but need to carry an extra gallon of water for a ways, you would then be a bit over 48 lbs. It would be far less comfortable, but totally doable. I would not want to carry 50 lbs steady for a week straight using this pack. Something like the Aether series would be better suited. The negatives? They are actually positives! I don't like the flappy jacky thing that gets in the way every time I need to open the top of the pack. I'm going to cut it out of there for a nice weight reduction. I also don't need the SUPER long waist straps and can cut them down by about a foot each. Yes, A FOOT EACH!!! There are more things I don't need on the pack that can be cut off. Why is this cool? I can get the weight even lower than listed without losing any feature I need/want. I could really hack at this thing and do some sewing to easily drop 1/2 a pound of weight. I obviously don't care about the warranty. haha

Hey John, Awesome review! I tested this pack out last weekend and agree--the Anti Gravity suspension system in incredibly comfortable. You're also definitely right about the waist straps being super long. I had more than a foot of excess as well.

The most comfortable backpacking pack

Familiarity:
I've put it through the wringer

I got this for my husband after I got my self the Osprey Aura 50L. He liked the idea of the anti-gravity suspension system so decided to try it out himself. He loves this pack and enjoys backpacking with me even more because of it. He likes the 65L because he prefers having the room if he wants to be a little extra on our backpacking trips. But being able to remove the brain is a helpful option if we're just going on an overnighter and don't need to bring as much stuff. The stretchy pocket is perfect for snacks and rain gear to grab quickly. He also likes that this packs stays up on his narrow hips well and doesn't hurt his back. His last pack never stayed up so all of the weight would fall on his shoulders. He doesn't have that problem with this pack and is able to adjust the hip belts to his comfort. He's 5'7 with an average torso and the size small fits him well.

Terrific pack

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

I have an older model osprey and I love it so I bought this one for Christmas for my son whose smaller framed than I am and slightly longer. I say this because otherwise I'd take his! Since my osprey they have made smart updates that make it easier to access, more usable pockets and the breath ability on the backpack to back is incredible. Lots of adjustment, interior water bladder., smart straps and buckles. My son and I have done several weekend hiking campouts in prep for the AT week this summer.

I bought this for my partner for Christmas and he loves it! We haven't had a lot of opportunities to use it yet, but so far he thinks it's perfect. The heat mold able waist , all of the pockets and the bottom access features are the best. Look forward to taking it to Kings Peak this summer!

I like this pack a lot. I bought it for hiking/camping/backpacking and it has performed well in all three areas. Lightweight and breathable, lots of storage space, and it looks sharp as well. I love Osprey's guarantee on their products so this bag was a no brainer when it was time for a new one. I use Osprey for 90% of my packs and wouldn't hesitate to recommend them to anyone.

Great first pack

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

This is the first pack I've ever owned and I fell in love with ever since I put my eyes on it. I have a red med. pack (6'2"), and it looks amazing. I've taken it on a couple of hiking and after breaking it in a bit it works great! I love the compartmentalization that it has, as well as the ledge separating the bottom from the top (if you want). All the straps help keep it tight and secure without any sliding. I did get squeaking like the others mentioned after using it a bit, but it went off and on. We'll see if it continues. Used for a day hike to carry all my friends stuff, as well as a weekend trip. I handled everything with room to spare. Can't wait to take it out on more adventures.

It squeaks

Familiarity:
I've used it several times

Pretty good bag. The suspension holds weight super well. And I like how specific you can get when making adjustments to the frame. The big drawback for me was that it squeaked. With. Every. Step. I looked into this and it seems to be a common problem with the pack. I would look elsewhere until they get this sorted out, or allow for time to return it before your trip to mountains.

We got it sorted out! Thank you for addressing this issue. Moving forward, all Atmos AG and Aura AG packs will be treated at the factory level for this issue. Thanks again, Leta Osprey Rep

Leta Kalfas, is there something that can do ourselves to fix the squeak.

A Light Versatile pack

Familiarity:
I've put it through the wringer

I use this pack for just about all my ventures, whether it be hiking, backpacking, climbing, and even ski mountaineering. I love how easily the zippers can be closed, as well as the various compartments around the entire pack. The added storage in the hip belts is a huge plus, as well as the removable brain. The only reason I gave this pack 4 stars instead of 5 is because the pack can get a little uncomfortable after about 35 pounds, but this very well could be becasue I need the pack fitted a bit better. Other than that, this pack is a phenomenal do-it-all pack.

Thank you for the review, James - I hope you are able to dial in the fit of that pack! Leta Osprey Rep

Great pack for light to moderate loads.

Just finished three days hiking over the Tetons. Fully loaded my pack weighted 40 pounds this is about the limit of what I would carry in this pack. That being said if you are carrying less than that this pack is very comfortable and adjustable. It has a great set of features it would be nice to have an integrated raincover but that's not a deal breaker. I highly recommend this pack.

Thanks so much, Scott! Leta Osprey Rep

Do you think one could fit a 60 meter climbing rope in the bottom sleeping bag compartment? 60m rope bundled up in a rope bag? I'm looking to use this pack for two main purposes: 1) winter backpacking (I usually use a lighter pack for summer backpacking) and 2) hauling traditional climbing rack + other climbing/personal gear out to the crag. Thank you!
