From Backcountry.com:
"Even though the Atmos 50 Backpack has already won Outside Magazine's Gear of the Year Award, Osprey updated it with a new low-profile back panel. This new design puts the pack closer to your back for better support and more comfort on the long haul. Several pockets and a large front flap help you keep everything well organized. Plus, you still get the mesh back panel and breathable straps that you trust to keep you cool during scorching summer hikes."

From Moosejaw:
"Free Shipping. Osprey Men's Atmos 50 Backpack (Fall 2009) The Atmos 50 by Osprey is for fastpacking - overnight to an entire hike of the AT.The all-new Atmos Series addresses the ultralight revolution as only Osprey could - with a suspension that really carries weight, and fabrics and materials that will realistically stand up to the rigors of use. The AirSpeed suspension sets the Atmos Series above all other ultralight packs. The Atmos frame is 6005-T6 alloy aluminum with two 6in. x 5mm fiberglass struts providing flex in the middle. Unlike other mesh tensioned backpanels that are simply flat panels suspended from 4 tensioned corners of an X-frame, this panel is 3D contoured. Additionally, there is a lumbar contour at the bottom and the backpanel follows a back curvature. All contact surfaces are either breathable mesh or perforated, molded waffle foam. The backpanel supports the load well because it is under drum-like tension. When wearing the pack, rather than compressing the load with comp straps at the hips, the back sinks evenly into the lumbar area providing comfortable uniform pressure with no hot spots.With durable 210D fabrics and a weight range of 1 lb., 15 oz to 2 lb., 13 oz. these packs are both light and strong. Two quick release web straps at the top end of the inside of the backpanel provide attachment for your hydration bladder. These straps slide on the aluminum tubing at the top and can be positioned on center or two hole connection points. A central exit for the hydration tube allows routing to either the right or left shoulder strap. The hipbelt and shoulder pads are a waffle molded EVA with perforations. This allows for minimal surface contact and superb ventilation. The hipbelt has a mesh zippered pocket on each side for quick access to energy gel and the like. On the front of the pack, you'll find stretch woven lycra front and side pockets and welded water resistant zippers. Specifications Small: Volume cu.in./liters: 2800/47.

After doing the research and trying on packs I chose this one as my next pack for many reasons, one of which is the quality of product we have come to expect from Osprey.
On my very first weekender with it the material tore."

The fit is amazing! At my height of less than 5 feet, it took me a few days to try out numerous women's and kids' backpacks."

However, in contrast to some of the other reviewers, I'm not fond of its frame system."
