Osprey Packs Atmos 50 Pack - 2800-3200 cu in

I've been trying to slowly convert all my gear over to packing lite. This years money went into buying a pack. At three pounds for 50 liters, the Atmos 50 was on a short list. Although big enough for my gear (I had extra room), I couldn't get the bear can to fit inside! I was prepared to attach the can externally, but there were only limited options for doing so. I like the way it fit, but left me a little sore. Also, maybe I'm just frivolous, but It would be nicer if it had an external pocket that was a little safer from precipitation.

I've had this pack for almost 2 years and am generally pleased with it. It fits enough gear for a weekend overnight and I love the hip belt pockets for my camera and energy bars. My only complaint is that when the pack is fully loaded with gear, food, and water, the shoulder straps dig into my shoulders pretty hard. I guess you have to give up some comfort and padding if you want to keep the weight of the pack down.

Found out while training for a climb that the shoulder straps cut into my clavicles on both sides. Had to buy dense 2" foam padding and pack cloth to make padded straps that went from the top of the shoulder all the way to the bottom of the strap. Sewed them onto the existing shoulder straps with upholstery thread. Go figure. Otherwise it is a good pack, but doesn't feel very roomy for it's external size.

Found out while training for a climb that the shoulder straps dug into my clavicles on both sides, and one of the rear struts dug into my back. Had to buy dense 2" foam and pack cloth and make new padded shoulder straps. Sewed them onto the existing straps with upholstery thread. The pack also did not feel very roomy inside as compared to its external size. I did like the small pockets on the waist strap.

This backpack was exactly what i was looking for my trip to Europe. It handled the flight being checked in and was comfortable to wear taking trains and walking through random cities. I would tell anyone to get this if they are looking for a ruck that isn't too big and still would like 4-5 days of gear along.

I've been using this backpack for the last year and a half, and I've come to love it. It's super lightweight, durable, and comfortable to wear. In my experience, it works best for weekend trips, when your load isn't too heavy. They key to this pack is in the packing - if you take things out of their stuff sacks and pack them individually, you can get tons into it. 50L gives you plenty of room for 2-3 nights. I'm 5'7" and the medium fits me perfectly. If you're looking for a lightweight backpack that feels great when you're moving fast, get the Atmos 50.

It almost weighs nothing! Fabulous ventilation system, incredibly comfortable while carrying up on trails! Suitable for 3-4 days backpacking; I adapted external water bladder in order to fit all gear into main compartment.

At 57 years old and many years of backpacking I retired my old "heavy" pack and went for the Atmos 50. I have done 5 overnight trips with it so far and am delighted with it. It's light, carries well and has tons of places to keep gear. Although it is new it seems very durable and I found the straps comfortable from the start.

This pack's shoulder straps and hip-belt are definitely some of the most comfortable I've come across. The springy-mesh action for the back panel looked pretty odd to me at first, but I quickly realized how great it is - hiking around in 100-degree heat without getting a full-on back sweat was great. The clip-close front pocket works well for stashing climbing shoes between routes, and front side pockets are great for snacks. The only things that really bother me are the hip-belt pockets - they stick out and bother my arms. No worries, though - a quick snip-snip and all is well.

My wife carried this pack on her first backpacking trip (seven days in the Sierra Nevada) and loved it. Although it wasn't large enough to hold a bear canister, it did hold everything she needed. She like the adjustments, the cushy hip belt, the color, the durability and the two side, zippered pockets and two side, unzippered compartments. About the only improvements we could recommend is a different color for the main compartment straps (my Osprey has this and I love it) and longer straps at the bottom to hang a tent or sleeping mat. I carried a much large Osprey and we are both sold on the brand.

After hiking over 3,000 miles this year with the Atmos 50, I can attest to the quality and durability of the product. Like all Osprey packs, it takes a day or two to break in the shoulder straps, and then you’re good for a decade. I think it’s funny how outdoor gear sales people try to convince would-be customers that packs like this can’t handle the needs of extensive trips. Well, leave the canned food and the blue jeans at home and you’ll be fine. I love this pack. You get the best of the internal pack with the breathability of an external frame. If I could have any pack in the world, for long-distance hiking, it would be the Atmos 50 I already have. Sure it’s dirty and has a few small dental floss and duct tape patches, but the pack has no major issues and has treated me well. It's going to hike the CDT with me next year!

Took the new pack on 4 day backcountry hut trip and loved its light weight, great shovel pocket, comfortable ride. Belt pockets are handy for snax and gadgets, but would be better if one of them was water-tight. This pack was the envy of the trip.

This pack is about the coolest thing going. It is really light weight and has great venting. I have been doing some hiking in the desert and this pack has been perfect. You can put an ton of gear in this thing. If you only have a little gear it compresses really nicely. This is the prefect day hiking or overnight pack. Nice work Osprey!
