Osprey Atmos AG LT 50 S/M / Night Shift Scoria Blue
New version of the Atmos AG 50 backpack. For trekking and multi-day trips, where comfort and ventilation are most important, you cannot find a better backpack than the Atmos AG 50. It is a backpack with an extremely airy back, comfortable shoulder straps and side belt. The adjustable AntiGravity 3D back is designed so that even when heavily loaded you do not feel the real weight of the backpack. Thanks to the good distribution of weight on the shoulders and side belt, the weight can also be adjusted with the fastening straps, which allows the backpack to perfectly adapt to your body. The perfectly organized main compartment has space for the HydraForm hydration system (up to 3 l). Two zipped pockets are also located on the side belt. A rain cover has also been added, which comes in handy in unpredictable weather conditions. Poles can be attached with the easy and fast Stow-on-the Go system, which allows you that you don't need to take off the backpack. The are also ice ax loops and removable straps for attaching a sleeping pad or bag.

I bought this pack to compare to an Aether 60 purchased in 2017. I was looking for a similar capacity pack, with a lower base weight with more modern features.After testing this pack out fully loaded for a desert backpacking trip, I believe the Atmos AG LT meets all of these requirements!Pros: The revised seamless hip belt completely eliminated the host spots I often experienced with the Aether. This is undoubtedly the most comfortable pack I've tried on. The torso adjustment system is so much easier than the older velcro system. Typical amazing Osprey build quality. Just the right amount of pockets and straps for my needs. Integrated rain shell compartment.Cons: The Anti-Gravity system sometimes can be a bit noisy. Nothing crazy, a squeak here or there. May ...

May disappear with use. Maybe could be a little lighter with the use of thinner fabrics in places.This pack performed fantastically with a full 40lb load, the upper limit Osprey recommends for this pack. I'm looking forward to many awesome years with this pack!

This pack was a huge disappointment. The materials, workmanship, and light weight were all impeccable so its worth one star for that. However the most important aspect for any backpack, just like a pair if hiking shoes, is the fit. Or more properly, the way the pack carries. It should feel like its an integral part of your body. This pack is approved by some but it is difficult for me to see why. The pack carries off center, which is to say too far to the rear creating a feeling of being off balance and swaying like a poorly fitted external frame pack. The hip belt is integrated with the Lightwire frame and this further complicates matters because the weight of the pack with a rearward center of gravity puts major pressure on the front of the hips instead of bearing ...

I have been hiking for six decades and I'm sorry to say this may be the most uncomfortable pack I have ever worn.

I bought this pack about a month ago, as I was headed on a backpacking trip to Iceland. I didn't have time to go get fitted and I figured that I could return it if I didn't like the fit. From the moment I tried it on, I loved it. The formed hip supports funnel all the weight onto your hips and pelvis and off of your shoulders. It is super easy to adjust on the trail to alter where the weight lands. I usually get headaches from carrying backpacks, as I carry a lot of tension in my shoulders anyhow and somehow, I actually felt better than usual while wearing this pack. It was so comfortable that I never dreaded putting my pack back on after a rest. I carried ~30 lbs and could it could have handled more. After walking around in a couple airports with this on, I'm ... MoreI bought this pack about a month ago, as I was headed on a backpacking trip to Iceland.

After walking around in a couple airports with this on, I'm considering having this pack be my carry-on in future as it is extremely portable. I had a friend who bought this pack too, and she said her anti-gravity suspension creaked when she walked. Mine did at first, but after putting weight in it, the creaking went away. The only thing I would change about this pack is the length of the adjustable part of the shoulder straps. I don't have much room to tighten the straps when I've just gotten them to not be loose. Overall, I consider this pack to be one of the best high-ticket purchasing decisions I've made in awhile.

Did a lot if research to pick out this pack. Measured my torso and body to select the right size. It arrived fast even over the holidays and had every feature advertised. At first I didn't quite like the fit, but 30 seconds on YouTube had me realizing I hadn't adjusted all of the many adjustment points on this bag. Voila, perfect fit. What I love is that the frame can be adjusted up and down within the pack itself, making it sit in just the right spot on my long torso. My only complaint so far is that the chest strap isn't adjustable up/down. I like the removable flap to separate the bottom compartment (let's me stick my tent poles down into it to reduce the overall height), and it has just the right number of pockets. The side waterbottle pockets are great too. The ... MoreDid a lot if research to pick out this pack. Measured my torso and body to select the right size.

This backpack is a real game-changer! I have always liked backpacking and have done it with different quality packs, but this purchase has made my backcountry trips much more pleasant. No bruised hips and sore shoulders. It is for sure a very featured pack, but the frame and suspended mesh back that what makes it so special. It is all one nice, meshy wrap around your back, hips and shoulders. Comfortable and cooling! It has a women's specific fit, and storage for everything, for my 65 L there is the option to take "brain" out and use a flap lid to protect your gear and minimize weight.I definitely found the backpack that suits me the best. And for anyone looking for a new and reliable backcountry "buddy," I recommend giving the Aura a try. The key to picking the ... MoreThis backpack is a real game-changer!

And for anyone looking for a new and reliable backcountry "buddy," I recommend giving the Aura a try. The key to picking the right pack is to try as many options as you can, compare, try packs with weight in them, and do not forget about size (I am not about volume, it is about torso lengths). If you are new to this, please always ask for help. At MEC, a backpack fitter is always available to assist you.Aura has been with me for more than a year, with trips up to 10 days in the wilderness, and no problems and no regrets! I absolutely like it!
I bought this backpack after doing a lot of research because I wanted to make sure I got the most comfortable backpack available for my sore back. The weight was my concern considering other options at half the weight or less. So far the fit is amazing and I haven’t developed any sore areas from it. After walking awhile, I notice the weight less and less. I do have a few concerns 1. While it’s possible to reach back and pull the water bottle from the side mesh pocket, it’s very difficult to put it back in 2. The hip pocket zipper will not close all the way using one hand 3. The hip pockets are too far back to be useful 4. The sternum strap is in its lowest position but still feels way too close to my neck. Overall I am happy with this pack. I will review again after ...

I’m getting back into hiking and camping now that I’m retired. I researched lots of backpacks and then went to check them out at the REI store. I picked the Osprey and sure am glad I did. My wife and I did an overnight trip with a five mile hike up/down mountain to stay on top of the mountain. My wife has some life-long medical issues and a mile into the journey could no longer carry her pack, though she was good to hike. I loaded all her gear into my new Osprey pack, along with all my stuff. It was heavy but saved our trip. The Osprey was comfortable and transferred the weight to my hips - not shoulders - and hugged my back for balance. This was a trial by fire and the Osprey was tremendous. I’mso glad I got it.

I needed to replace my 15-year old Osprey backpack, which I LOVED because of the nice air-flow between the pack and my back. I was happy to see that the new version had the same mesh design, but was not convinced about the comfort of the stiff, molded hip belt when I tried it on in the store. I bought it anyway (couldn't find another brand I liked better). To my surprise, this model was a real improvement! Although it's not quite "anti-gravity", the hip belt really does focus the weight where it's the most comfortable for me (right on my lower back dimples), and I feel no weight on my shoulders (my old Osprey would pull on my shoulders, no matter how I adjusted the straps). The big downside to this belt is that it's hard to put on: you have to pry it open to get it ...

The big downside to this belt is that it's hard to put on: you have to pry it open to get it around your waist. Finding a big rock to sit you and your pack on helps; if available, a friend's assistance also works. Another minor issue with the belt was some chafing in the front, but those spots toughened up by my second backpacking trip. Overall, I'm really happy with this pack!
