OspreyAtmos AG 65L Men's Backpacking Backpack, Black, S/MBluesignBluesignBluesign

I haven't actually hiked with it yet, but I'm pretty much in love with it already. I've been gearing up, and working on getting a base weight of 25-30 pounds which this handles no problem, of course. I love how you can access the main compartment from top and both sides.And the outer pockets and additional storage are well laid out. It's truly designed so well I'm having difficulty criticizing it. It's actually my first real backpack, so I don't have much frame of reference, but I can say that loaded up with 30 pounds, It feels surprisingly light on my back.I'm 5'5" and male, by the way. I'm still dialing in the torso length adjustment but seems to be a good fit for my body (the small/medium 65 L)Oh and I didn't even know about Osprey's "almighty guarantee" before buying the Atmos but it certainly sweetens the deal! You can return the bag any time, no receipt, and they'll send it back repaired (you pay shipping). That's pretty sweet! And pretty much means I'll never have to buy another one!

After 28 years, I finally retired my Camp Trails 75-liter pack. It's still got plenty of life left in it, but I was ready for something with a more advanced suspension system and compatible with hydration packs.A few years ago, I bought my son the Osprey Atmos AG 50 and was so impressed that I concluded that the Atmos AG 65 would be my next pack. Finally pulled the trigger this year, and am thoroughly pleased.Things I love:1) Fit and Comfort. I'm a big fan of the AG suspension system. It's easy to adjust and effectively distributes the weight. It really does make the pack feel lighter than it is.2) Integral Rain Cover. When the rain lets loose on the trail, it's so nice to just unzip the bottom pouch and pull the rain cover over the pack. When the rain subsides and the cover is dry, just fold it up and zip it back in its dedicated pocket. It's tethered with a lanyard inside the pouch, but you can remove it if you need to.3) Organization and Access. I like that you can access the main compartment through either side. The sleeping bag compartment is just the right size for my bag, pad, and pillow. The stretchy outer pouch is great for quick stowing of a hoodie or boonie hat. There are enough pockets to be thoughtful about organization but not so many that it's needlessly complex.4) Torso size adjustment is stupid easy.Some misses:1) The waistband pocket zippers won't zip closed one-handed, no matter how I try (they curve up and then down again instead of being straight). Kind of a hassle to have to use two hands to close it up. This may vary from pack to pack as another family member with an Atmos AG 65 pack could zip them up one-handed. His was a Large size, so maybe they have different pocket dimensions.2) The bottom of the pack is not flat, so you can't stand it up on the ground -- it has to be leaned up against something, and even then, it wants to tip over or slide out from under itself.Niggles:1) I think I would have preferred dedicated water bottle pouches on each side instead of the dual-access stretchy pouches. They work, though (I use them for sunscreen and bug spray).2) The edges of the brain don't have a hem that extends down for a tidy mating between it and the main compartment (loved that about the old Camp Trails pack). It doesn't affect function, but it just doesn't look as tidy when cinched.3) Not super keen on the color options. Would like to have a grey option, like the women have with the Aura AG 65.4) It's a bit of a pain to adjust the straps on the brain because they're underneath. Similar nuisance for the "removable" divider between the main and bottom compartments (have to unzip the side access zipper to get to it, and it's not a buckle -- you have to thread the webbing).5) The strap to hold the hydration bladder could stand to be a little longer so it can sit lower, making more room for the tube to go through the opening in the pack. (I'm using CamelBak hydration bladders; did NOT like the fold-over-style Osprey bladder. At all.)Style Points:1) Emergency whistle molded into the chest strap buckle.2) Waistband cinches pull forward instead of backward. I makes it easier to take up all the slack.3) Mesh suspension system provides some breathability between the pack and me.4) The pull tab on the main compartment cinch makes it so easy to fully open with one pull.All in all, it's fantastic pack. Just returned from a trip to Red Castle Lake via the Bald Mountain Trail from East Fork Blacks Fork on the north slope of the Uinta mountains in Utah. It's 10 miles each way with about 2,300 feet of elevation gain and every type of weather. This pack was comfortable the whole way, stayed dry in the rain, and carried everything I needed with ample room.If it has the longevity of the pack it replaced, I'll be a happy camper! Hah...hahah...Other info in case it's helpful:I'm 5' 10" and 155 lbs and chose the Small/Medium. My total pack weight was 35 lbs (41 if you count my camera, two lenses, and two spare batteries).Primary gear included:> North Face Stormbreak II (love this little tent).> Kelty Cosmic 20 sleeping bag (in a 10L REI compression sack -- so tiny!)> Therm-a-Rest X-Therm NXT sleeping pad.> Trekology Aluft 2.0 pillow.> MSR WindoPro II stove and fuel.> Generic Amazon ditty bags of various sizes (brilliant for organizing stuff)> Sawyer Squeeze water filtration kitAgain -- bag, pad, and pillow all fit easily within the sleeping bag compartment of the pack.

I love this backpack. I have used it over 4 times already for a trail over 15 miles. You can tell the difference from this to anothe4 brands. Im 6'3 with 190 pounds and this perfect to me.

I love this pack. It fits everything I need for a weekend trip. My stuff isn’t ultra light either, so I need all the space I can get. Very comfortable. Great support.

I loved how this pack wears for moderate distance hiking. I used it for a 30 mi trip in the AZ desert. 65L is plenty of room for the tent, sleeping bag, hammock, camping inflatable mattress, spare clothes, 4 days of food, small daypack, camping cookware set, 2L water, and water shoes with a little room to spare (if you want extra weight). A definite plus is your back doesn't get all sweaty due to a gap between your back and the pack. The only complaint I have is that it won't stand up on its own on the ground. It must lean on something due to the bags shape. It's always falling over if it's not laying on the ground.

Very well made backpack, has all the features it describes in the sales ad. Highly recommend for this size backpack.

Excellent sturdy back pack. Purchased this for my son who spent 3 months in Europe walking the El Camino trail. It held up well with no rips or damage. Very good quality. Would highly recommend.

Great bagpack, light, efficient, and highly useful
