The Osprey Atmos 50 Backpack is coming up threes: 3,000 cubic inches in just a tad over 3 pounds of pack. Designed for those that want to keep it light on overnighters and multi-day trips, the Atmos 50 Pack organizes and hauls all the essentials. Its adjustable harness, mesh-backed suspension system and quick-fit hipbelt mean you’ll barely notice that you’re muling provisions for half a week.
Lightweight versatility at it's finest. The Atmos 50 from Osprey is truly a do-everything pack. The suspension frame keeps air circulating through the back panel so you stay well ventilated. An incredibly adjustable hipbelt and shoulder harness provide a fine tuned fit for better comfort. Multiple compression straps secure your load and reduce pack swing so you can be confident no matter where the trail leads.
A long-time favorite among AT thru-hikers and fast-and-light backpackers, the Atmos 50 combines both durability and lightweight performance. A redesigned harness and adjustable hipbelt now provide even better comfort and fit.
The series that redefined expectations about weight, ventilation, and comfort in backpacking, is about to do it again. The radically updated AirSpeed™ suspension of Osprey’s Atmos now provides customized fit, with fully adjustable torso length, interchangeable harnesses, and adjustable hipbelt fit. It all adds up to an even better fit and greater comfort on the trail.

Used this pack the entire length of the AT in 2012 and loved it the whole way. I have 2 other Osprey packs (Argon 85 and Aether 60) and this one fits the best. I have the previous model, but several of my firends had this newer version and not much has changed. In fact, I will say that about 80% of the hiker class from 2012 had some model of Osprey pack. The Atmos and Exos were the most popular, but did see a few Talon 44's and Kestrel models. The girl I hiked with had a Gregory and wished she'd bought an Osprey after hearing such rave reviews by fellow hikers. 2184.2 miles equals a well tested product and high approval rating! If you are planning to thru-hikeor just looking for a great pack for short trips, do yourself a favor and buy this pack!
In addition, I'm 5'9" and have a 31" waist. I bought a Medium and was a perfect fit.
I was hoping this pack would be my pack for doing a long thru-hike this summer. Supposedly Osprey revamped this pack from previous years to allow for more weight carrying. Their website indicates max loads from 35 to 45 lbs. Backcountry.com indicates up to 35 lbs. I gave the pack a few trial runs with up to 35 lbs and anticipated going higher.. At first the pack seemed great, but when I went for a 16 miler one day with 35 lbs, the hip belt became unreasonably uncomfortable after about 5 hours. The hip belt design on this pack seems to be a total afterthought in comparison to the rest of the Airspeed suspension design. The hip belt design creates pressure points where the hip belt meets the back of the pack. Otherwise the Airspeed suspension system worked great at minmizing back sweat. The rest of the pack seemed great, but unfortunately for me the pack ended up ebing uncomfortable, maybe because my bodytype is very thin. YMMV
I had been waiting for Osprey to update the Atmos line so when they did I finally purchased this one in early 2012.
The good: I love the packbag design with stretch side pockets, front pocket, and dual-zppered front pockets. I can easily get a week's worth of gear and food inside, with pretty good organization. I really like the back panel that offers good ventilation, and Osprey is smart to keep exposed thread/stitching to a very minimum. In my experience, exposed thread lines (especially on the backpanel and straps) get full of sweat and trail dust, then get abraded until they fall apart. The hipbelt is comfy and nicely adjustable, and the pockets are a nice size and easy to get into.
The 'could be better': As a former long-distance hiker, I never use the top lid. Took that off right away and am really disappointed there is no strap to tighten down over the top of the storm collar. This is a real pain not to be able to cinch that down, bring the weight closer to your back and keep things up there from wobbling. Every pack I've ever owned has had one of these but for some reason Osprey left it off this one. Major minus.
Also, when the pack is fully stuffed and I go to cinch the side compression straps, often times it pulls apart the zipper on the top of the dual front pockets. I have to be real careful about how tight I cinch them so that the zippers don't pull open as I'm hiking down the trail and have everything fall out.
Other than that it's pretty well made. I appreciate that Osprey uses higher stitch-counts than most pack manufacturers nowadays. That really helps hold everything together over the long haul. I'd hoped to keep this one awhile but am keeping my eye out for possible replacements due to the issues above.
