Osprey Atmos AG Backpack - 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."

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.
 Osprey Atmos 50 Litre Backpack Small Medium Large
Back Length 16-19"/40.5-48cm 18-21"/47.5-53cm 20-23"/51-58cm
