Winner, Outdoor Gear Lab Editor's Choice Award, 2018 

"The Osprey Atmos 65 AG is our OutdoorGearLab Editors' Choice for Comfort and Ventilation because of its ultra-comfortable frame and suspension. Not only is it comfy and well-ventilation, but it features one of our review teams' favorite overall pack designs. Plus, the new 2018 model features improved shoulder strap padding that tapers depending on the location. It's also uber cushy around the wearer's shoulder straps and was easily one of the most comfortable packs we tested. As far as its suspension goes, once you put the Atmos 65 AG on, you'll be surprised how evenly the AG or Anti-Gravity suspension spreads the load out, creating a relatively even, and pressure-point-free feel. The AG suspension takes the trampoline-style suspension to a new level, incorporating the entire back panel and the waist belt; this makes the Atmos comfortable and able to carry loads up to around 40 lbs, making it the best feeling pack (to carry) in our review. Not only is the Atmos an excellent contender, but it features a ton of user-friendly pockets that will keep even the most organizationally driven backpacker happy. "

Winner, 2015 Backpacker Magazine, Editor's Choice Award

"Hauling big loads can be a soul- and spine-crushing experience, but the Atmos’s radical new AG (anti-gravity) suspension system throws conventional pack design out the window with stellar results. Unlike most big packs, there’s no foam padding or plastic framesheet in the backpanel. Instead, nonstretch mesh (with pencil-eraser-size holes) spans a steel perimeter wire throughout the back and continuously through the lumbar and hipbelt. It’s that lumbar and hipbelt contact that’s key: “It wraps gently but firmly around my hips—like a dance partner’s hands—with no gaps or rubbing,” one tester says. With complete contact throughout the entire back of your body, you get no pressure points, excellent airflow, and superior load transfer. You also get good adjustability: The torso has 4 inches of play and the hipbelt extends up to 6 inches. Four compression straps (the lower two are V-shaped) connect directly to the frame, allowing you to squeeze down and stabilize smaller loads. Pockets aplenty kept us organized, and we liked the removable toplid (keep it attached for 9 liters of extra space or remove it and use the integrated flap cover, saving 6 ounces). Both the Atmos and Aura (the women’s version) come in 50- and 65-liter models."

"At first sight, Osprey’s Atmos AG 65 made us curious as a jury. The promising initial impression is confirmed when you put it on your back. The full-contact carry system literally covers the back and hips, but still allows good ventilation even when heavily loaded. With this carry system, Osprey has embarked on an interesting new approach, which requires no foam pads."

Sizing and Fitting of your Osprey Pack

      Fit is the key to pack performance. Take the time to get it right.
      Most Osprey packs are available in multiple sizes to fit a range of torso lengths. To find your torso length, have a friend measure your back along the spine (as shown in the picture below) from the level of your iliac crest (the top of your hipbones) to your C7 (the knobby bone at the base of your neck).
Use the table below to determine your pack size.

Fits perfectly. Great pack and has been used for multi day already. Blown away by the fast postage and delivery times. Osprey Online size guides were useful for ensuring correct fit. Cheers.
