From Moosejaw:
"Free Shipping. Osprey Atmos 50 Pack (Spring 2008) - Outside Gear of the Year Award 2007 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.

From Backcountry.com:
"The lightweight Osprey Atmos 50 Backpack earned Outside Magazine's Gear of the Year Award. Despite being lightweight, this Osprey backpack has a strong suspension system and provides back ventilation so you can hit the trail in comfort. The ideal load for the Atmos 50 is b35 pounds of gear, clothing, and food. The suspension system features lightweight but sturdy materials, such as titanium struts, which provide excellent flex as you bound down the trail. Breathable mesh on the back panel ensures you won't sweat buckets underneath your pack. In addition to the main compartment, this backpack has several pockets where you can stash energy gel, a jacket, headlamp, and other gear you want accessible. Put your hydration bladder (not included) in the internal bladder sleeve and drink up."
From Altrec Outdoors:
"If there was ever one nagging critique about most well-designed, ultra-ergonomic Osprey packs, it was the weight. Osprey's Atmos 50 silences the critics with over 3,200 cubic inches of pack space in a supportive and functional pack design that weighs less than three pounds. If you ever wanted a supportive and lightweight backpack for moving fast and far, the Osprey Atmos 50 is easily one of the most comfortable light packs on the planet. Anything that touches your back is covered with a breathable mesh or a special perforated waffle foam that won't heat you up like conventional backpanel fabrics. The backpanel on the Atmos 50 is stretched taut so the load sinks evenly into the lumbar support area instead of riding on your hips, resulting in uniform pressure that neutralizes hot spots. Two quick release straps on the other side of the backpanel attach to your hydration pouch for fast refill access and versatile hydration tube routing. If you're looking for a lightweight pack for fast overnight trips or minimalist backpacking adventures, the Atmos 50 backpack is one of the lightest and most comfortable designs you'll find today."
From RockCreek:
"The Atmos 50 provides the ideal volume for your next ultralight backpacking experience. At 3000 cubic inches and with a weight well under 3 pounds, you can carry your ultralight essentials with ease and comfort. A traditional floating top pocket/top load design and twin front pockets with welded water resistant zips makes loading easy. Other features include an internal hydration sleeve, zippered mesh pockets on the hipbelt and removable sleeping pad straps.The Osprey Atmos 50 received Outside Magazine's 2005 "Gear of the Year" award. The reviewer cited the Atmos' "matchless mesh suspension setup," which "saves aches and ounces, while the main compartment smartly stows as much or as little as you like.""

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."
