Hiked nearly 2,000 miles of the AT with this pack
by Amazon Customer (5 out of 5 stars)
June 19, 2015

I started my Appalachian Trail thru hike with the Gregory z65 pack. It was a decent pack but the shoulder straps started to tear on me a couple hundred miles in. I knew I needed a new pack so when I reached Hot Springs, NC I went to the outfitter that was down the street to see what they had. I did some prior research and was planning on purchasing the Osprey Aether but it turns out they didn't have it, bummer. However, they did have the recently released Osprey Atmos AG pack. I didn't know much about it so I went back to my room to do more research. Well, like I said it was a new pack so there weren't many reviews on it. The few that there were were positive though. I was still skeptical and didn't want to spend that much money on a pack that I may not like. I bite the bullet and the next day decide to purchase the pack. I bought a lot of new gear while on the AT, and I'll say that this pack was by far the best money I spent on the whole trail. I can't say enough good things about this pack but I'll do what I can.

The new suspension system is great. It is a giant strong mesh panel that rests on your back. It feels like the bag is just floating on your back. Doing so means it carries weight extremely well. While on the AT I carried roughly 40-45lbs. That proved to be too much for my Gregory pack but the Osprey did and amazing job with it, at times I'm sure I've even gone past 50. You can also adjust the pack to have it lower or higher on your hips.

One of the best features of this pack is the angled water bottle pocket, with my Gregory I had to take the pack off just to drink water. With the Osprey I could easily reach on either side to grab my bottle. It was a game changer and saved a ton of time. More time equals more miles hiked. The mesh pocket will easily fit a 32oz Nalgene bottle.

The hip belt is different from other packs. It feels as if it's trying to hug you, wraps around you very nicely. You have the option of extending the belt if you have a bigger waist but I kept mine all the way inside. I will say the the straps for the hip belt are very long, this pack could seriously fit a sumo wrestler. I had to use duct tape and roll up the extra slack. Another little issue was the hip belt pockets, you can't fit much in there, it would be nice if they gave you more room in there. I was able to stuff four snack bars in one pocket and my camera in the other which was a tight fit.

If you like extra pockets then you'll love this pack. There are two zippered pockets in the brain. The bottom one is pretty big, I could fit a ton of extra gear in there. The top one is smaller but I was still able to jam a good amount of accessories in there. There are also two side zippers on the front, one on the left and one on the right. They go pretty deep so you can again stuff a good amount of gear in each of those. On top of that, the front mesh pocket that Osprey is known for can also fit a ton of stuff. I would keep all my rain gear that I would need quick access to in that pocket. I met other hikers that stuffed so much gear in there that the pack looked like it was pregnant. I don't know what kind of mesh material Osprey uses but it's pretty tough. That being said, I did puncture a small hole in the mesh, don't know how it happened, must have caught it on a branch or something. I threw duct tape over it to fix it. There is also a sleeping bag compartment on the bottom, I never used it though.

The pack is very durable. The material just felt stronger and of better quality than the Gregory I previously used. Up north on the AT I had to deal with an insane amount of tree blow downs and sitting down and sliding down rocks. Many times I swore I tore a hole but when I checked the bag was fine. I did however get my water bottle pouch caught on a sharp branch that tore it. It still worked but there's just a hole there now.

The sternum strap is also a little lower on this pack. I actually liked that because it wont rub your collar bone while you hike. The sternum strap also has a built in whistle like the rest of the Osprey line of packs.

The bottom straps on the pack for a tent or sleeping pad has a lot of slack which is a good thing. You shouldn't have an issue fitting anything on there. I just kept my one man tent down there.

The pack weighs in at 4.5lbs (73.4oz when I weighed it after my hike). This is pretty heavy for a 65L pack. However, this is a 4 season pack (in my opinion) so it's tougher and more durable. More weight will usually accompany that.

Overall, this is an amazing pack. I'll defiantly be a long time Osprey customer now. Any pack that can comfortably last you nearly 2000 miles deserves a 5 star rating in my opinion. I was with another thru hiker who started with the Gregory Baltoro 75L pack and after trying on my pack he got off the trail and got a ride two hours away to an REI and exchanged it for this pack. He ended up loving this pack as well and we both summited Mt Katahdin with it on our backs.

Pros
- Great suspension system
- Carries weight well
- Comfortable / Hugs your body
- Many extra pockets
- Durable

Cons
- Lots of extra loose straps
- Hip belt pockets aren't very big
- Heavy

UPDATE: 8 Aug 2015

I contacted Osprey about the two holes I sustained while hiking. I had the pack sent in (had to pay for shipping) and they sent it back stitched up. Not gonna lie, I was hoping they would give me a new pack but that was a long shot for such small damage.

Also, the Atmos AG is the new #1 rated backpacking pack according to OutdoorGearLab. They are my go to website for all things gear related.

The last pack you'll ever need to buy.....Seriously.
by B-Bear (5 out of 5 stars)
February 28, 2017

This is the last pack you will ever need to buy. Seriously, with the lifetime warranty offered by Osprey, you're good until your last backpacking days. I tried this on in my local outdoor store and I was blown away by the fit. They measured me and found that I am a medium, which surprise me since I am a big guy. The waist strap seriously hugs you and fits your body like a glove. I loaded it with over 30 pounds and couldn't even tell I had weight in a pack.

The online price is great, it was $50, plus tax less than my local outdoor store.

There are tons of pockets, which I love.

The anti-gravity system will keep your back airy and cool and fits to the contours of your back.

The zippers and pull loops are clearly of higher-quality, so these will last you a long time. I bought an Osprey bladder and it works like a glove.

There is no rain cover and I didn't want to spend another $50, so I bought a large Outad covers and it fits great.

There are a ton of external straps, loops, tighteners and pockets, so you can customize this to whatever your style is.

I would highly, highly recommend this pack!!

Lucky, thankful, best purchase of 100s here on amazon.
by Eugene Clark Bode (5 out of 5 stars)
July 10, 2016

First review here on Amazon, never felt the need to post anything; but about 10 days ago this pack literally saved my wife's life. We were hiking the four pass loop in Colorado and were going over Buckskin Pass; it was foggy but conditions were otherwise pristine. The pass was partially covered with snow so we managed to push through the snow and rock to the exposed trail. While we were waiting for our last member to reach the trail, my brother called out ROCK! Four large rocks were coming down the face towards our party. My wife turned her pack uphill and took a 60 pound rock falling from at least 100 feet up. I was right next to her and saw the rock hit her pack unable to do anything but watch. I rushed to her side and asked if she was okay. She broke out crying but she suffered no damage. The amazing part, we had emptied her pack the night before as her knee was giving her trouble. Her pack was 100% empty and saved her life. Damage to the pack was minimal; the metal frame and separation from her back completely dampened the impact. Can not put a price on this purchase, just thankful.

Best pack in my opinion!
by GrizzledAtoms (5 out of 5 stars)

This is the best backpack I've owned. I've used it on a few trips to Colorado on peak climbing expeditions and it has performed wonderfully. Because of the AG features it is not the lightest pack but it also is not heavy. That said, it is the most comfortable pack I have used. Once fitted correctly, it almost seems to disappear off my back! Ok, not really, but their design is fabulous. I've been training for the AT and already know that this is the perfect pack for extended trips. Some folks may not like that there is really only one front pocket but I like that. If I want to compartmentalize stuff, I like to configure it my own way with utility pouches. I also think that Osprey got the tool attachments right and I like the trekking pole attachment up front. It may not be the best for everyone but it's a nice option.

Can't find a better standard backpack out there
by James Smith (5 out of 5 stars)
March 3, 2019

If you are in the market for a testimony internal frame backpack good for a week or more on the trail then you can't do better that this! Really the build quality is top notch, the features such as removable top lid are great. But the best feature is the Antigravity suspension system. It really works if you adjust everything properly. I loaded this up with over 45lbs of gear and bags of sand. Walked around my neighborhood for 45 minutes. Felt great on my hips.

Took this to Rae Lakes with the same 45lbs total weight and hiked over 40 miles and up to 12,000 feet at Glenn Pass. It has the capacity for 5 days of food and gear, and even though I was tired, the pack always felt great!

Only 2 things are missing and really you didn't need them anyway. A rain cover (use a black garbage bag) and a day hike or accent pack (get a sil-nylon one).

Go to REI and get sized because the wrong one will not feel great like it should. Don't be an idiot.

Best pack yet.
by K. Goff (5 out of 5 stars)
November 8, 2015

Bought this backpack(Medium size) in early spring 2015 and have since gone on two backpacking loops, one 30 miler through the sawtooth mountains, ID, and a 27 mile loop through the Cascade mountains in OR...as well as 10+ day hikes in texas.

First off, this thing fits me like a glove...made for my back. It's basically like the backpack is giving you a great big bear hug, and it really feels like you are carrying less weight than you are. I usually stay around 30 lbs or less, so this is *usually* of no big concern, but you never know what may happen that can cause you to have to load your pack down. Example: During my loop in Idaho my Australian shepherd's pads got badly injured and she couldn't walk any further, so I had to literally put my 46 lb dog in my pack and carry her out. And though it was very heavy (I was probably at ~75 lbs) the backpack kept everything amazingly stable!(Picture is attached)

Secondly, it is one of the best ventilated of a pack this size that I have tried. The mesh suspension system on this pack really makes a difference in terms of keeping you cool/not-so-sweaty during the hotter part of the day. I live in Texas(105+ in summer), and I run hot naturally, so having a pack that stays relatively cool is of great importance, and this thing does it as well as any.

The pack also compresses and packs down very well. All the strapping and buckles are well placed and do a good job of really securing the load. In fact some things just worked out by chance better than I could've imagined:The elastic cords on the shoulder straps (that I believe are for Ice picks /Trekking poles) I ended up using to secure my Olympus outdoor camera, and it worked better than the dang case I bought for it! Kept the camera right in arms reach but very secure the whole trip.

One minor drawback is that the zippered pockets on the front of the hipbelt are so small they are almost entirely pointless. They will not fit a phone, gps, or even a clif bar. The only thing I put in there were some blueberries I picked on a trail, and my compact knife sharpener. However, on the rest of the pack the pockets are conveniently located and hold quite a bit more than they seem they should, so this makes up for it in my opinion.

Another small annoying thing was, for me, when I had the shoulder straps buckled together, the buckle itself sat a little too high up on my chest, and was just slightly annoying after 5+ hours on the trail, to where I ended up unbuckling it for the large majority of both loops.

Overall, though, this pack has just been amazing thus far for me, and I know it won't be for a long while, but my next pack will almost definitely be an Osprey.

Very Well Made - A winner from Osprey
by LT (5 out of 5 stars)
August 28, 2016

I've used this pack for a day hikes and overnight hikes = and plan to later on use for some longer section hikes of the AT.

Overall - I think it's an excellent pack! A few notes and Cons (which are more picky than deal breakers)

PROS: The Anti Gravity (AG) Suspension system. This has got to be one of the most advanced suspension systems on the market. Compared to some other suspensions - this system truly makes it feel like you're carrying less weight than you actually are. Virtually all the weight is transferred off your shoulders and onto your hips. The mesh is sturdy and lets your back breath while making for a soft ride. Can't explain it better than Osprey and some of the other reviewers - but long story short - it works as intended - to feel like it's lightened the load. Make sure you adjust it for your height and learn how to adjust it.

The 65Lis adequate for a few overnights if you pack smartly. Like the addition of the sleep pad straps that let you carry it oustside on the lower back of the pack, and the separator in the lower part of the inside of the bag works good enough to keep your sleeping bag at the bottom, but other small items can slip down past the divider which could get annoying. The H20 pocket works nicely for a water bladder - I use a 3L Camelbak Bladder that I had from another pack. The routing of the hose is in a good location. The various pockets on the outside of the bag are ideal for the odds and ends you need while hiking. The "Lid" on the top is nice to have as it's removable for a small daypack if necessary - but honestly it's a bit of a hassle to remove.

CONS - its kind of hard to see inside the bag to buckle/unbuckle the separator - some other osprey bags use a high vis line green color on the inside to make things easier - not saying that's the answer but its just difficult to see into the depths of the bag to latch the separator. Also call me old school, but I'd like to see some daisy chains to attach caribiners to the outside (just two or so) - there is virtually no good place to hang a caribiner. The ease of cinching up the top of this bag closed could be a little easier - but it can be done. My bag is fairly clean now but introduce some grit after a long hike and I'm not sure how easy this will be. Also note that I'm 6'4 and have adjusted the pack to the tallest possible configuration. If you're any taller than that - you won't have an ideal fit and may have to look into another system.

While I haven't put 1000+ miles on it (yet) - It's definitely quality and cut out for the challenge. Happy Trails!

Great comfortable full size pack
by OneMinuteReview (5 out of 5 stars)
October 3, 2016

Got this pack after much research deciding it seemed best for standard backpacking for a newer young backpacker. It is not the lightest or cheapest however for the weight (about 3.5) it is very comfortable, and assuming you are buying a pack for many years of packing, the added value here outweighed the additional cost (and a number are more expensive). Assuming you packed well you could take this on any long weekend or week-plus trip. My son tried this after using an old-school external frame pack and said it felt like not wearing anything compared to the old pack (that changed after 10 miles on the trail lol). When I called Osprey and asked what was different from this pack over the previous (non-AG) model she said this one had further improved suspension and felt "like a hug" which after trying it myself is true--the hip belt and back suspension is surprisingly substantial and does a very good job of keeping impact off both hips and back. Compared to a simpler pack, ultralight packers would likely find the structure too much. Proper adjustment and weight loading is crucial of course and like any pack better to leave as much at home as possible! One clear difference from lighter simpler packs like the Granite Gear is that this pack has the same or more compartments as old-school packs so is perhaps easier to use than the single cell packs. If you're looking for ultralight or ultra-simple this will be overkill, however if you realistically are not going to get your load down below 20 lbs then this is going to be way more comfortable than an ultralight. Interestingly these packs hold their value well--looking at ebay its pretty hard to nail a used one for much less than new however this pack will definitely last a lifetime--in addition to to state of the art design, it is extremely well made.

Awesome pack! Very nice design and awesome color!
by Patrick (5 out of 5 stars)

This pack is great. It's not the lightest thing on the market but it's extremely comfortable. It sits very well and the anti gravity feature wraps my back very well yet it's still breathable because of the mesh. I've taken this out on several hikes to test it out and I'm going to really put in through the ringer when I take it across the US on a very long backpacking trip. I chose the medium size(65 litter) and it fits everything I'll need with room to spare. The extra features like trekking pole holder, the large mesh pocket on back, the gear ties, etc... are very well thought out. If you're looking for a very comfortable pack for a fair price this is this pack. I've tried many packs and this is by far my favorite. The warranty through osprey alone makes this pack worth it. You cannot go won't with this pack.

Lives up to the stellar reviews
by Seabass (5 out of 5 stars)
March 16, 2016

Well, this pack sure lives up to the stellar ratings it gets all over the web. After years of using cheaper packs that are heavy, harder to load, and just don't fit right, I finally pulled the trigger on this gem. And, there's no turning back.

Last year, I hiked a section of the John Muir Trail with an old, cheap pack and I suffered through constant adjustments and painful shoulders due to a very poorly designed hip belt system. That was the last straw, and my research for a higher end pack began. Every review site I came across had the Atmos 65 AG either at the top of the list or within the top 2, so I gave it a close inspection at my local retailer. After loading it up with 30# of weight and getting it adjusted properly (always get fitted the right way!), I slung it onto my back and it just fit like a glove.

The hip belt is very robust but light, hugging my hips and adjusting properly the first time. The zipper pockets on the hip belt aren't very big, and seem even smaller because of the curve of the hip belt. Not a big deal, because they are still big enough to fit my day's snacks and also my smartphone (my GPS), my Carmex, and my keys/wallet. All the space that I needed, really. The adjustment pulls are designed to be pulled in together instead of out and away from center, which is the ideal way to really crank them down snug on your hips. The buckles do not slip whatsoever.

I'm 6'1, 235# with a 36" waist, and the large pack was almost too big. I can crank the hip belt almost completely closed to its stopping point, and I had to really shorten the torso adjustment (I have a longer torso than average, too). I could have bought the medium and it would have been perfect.

The sleeping bag compartment was plenty big for my patrol bag sleeping bag, compressed, and had a little room on each side for some extras like dry socks and a light windbreaker. The top main compartment opens fast with a very clever but simple pull tab that releases the tension cord clamp, and it tightens just as fast with a quick pull on the tension cords. It swallows up enough gear for a long hike and just seems to keep going and going. On the outside front sides of the pack are 2 tall and large zippered shallow compartments for your thinner items. Spare jacket, Tevas, dry socks, etc. fit in there perfect without sacrificing much space from the main compartment.

Lots of attach points on this pack, but not too many that you have extra ounces. The currently attached straps are enough attach points for me, and you get a couple more. Also, the hiking pole holding system is fast to deploy once you practice a couple times for those moments when you just need to hike without poles but need somewhere fast to store/deploy them.

The top of the pack is detachable with 4 release points, but those are also extension points that allow the pack top to extend higher. I store my required bear canister under the top of the pack and it rides very stable. Check out the Bear Vault BV450 for a perfect fit in this spot. I detached the top of the pack to see if I could configure it into a small summit waist pack, but I'll have to get some straps and a buckle to fashion a waist belt for it. It does not come with a waist belt system if you want to use it that way. Or, you can leave it off completely for those shorter trips where that extra space is just dead weight.

To give this pack its first test run, I loaded up for a one night backpack trip through a canyon with lots of rock hopping and essentially no trail. I wanted to see how well-balanced this pack rode, and how comfortable it was on non-traditional trails. I had 26.7 lbs in the pack, minus water weight, and I honestly kept forgetting I even had a pack on my back. I'm a large guy and not in top marathon condition, so this was such a huge relief to not have a pack that weighted me down like the others. I am extremely impressed at its balance, fitment, and loadability.

Overall, this pack really is a champion. If you're a thru-hiker or a weekend overnighter, this pack is versatile enough to fit your needs.
