The design is great, good quality of material, looks awesome too.

However my back is sore, and the bottom is not cane enough, thus difficult to pack stuff nicely and increase pack instability while on vigrous movement.

Free Shipping. Osprey Atmos 25 Pack (Fall 2006) For the absolute minimalist the Osprey Atmos 25 Pack by Osprey provides ample features in a small package.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: 1400/23.

Front slash pocket with water-resistant welded zipper, stretch-woven side pockets and zippered mesh pockets on hipbelt all help you organize your gear. Hydration-compatible design features water tube portholes; uses cavity behind mesh backpanel to hold reservoir (sold separately). Osprey's Airspeed suspension uses an aluminum alloy frame and twin composite struts for support and flexibility while carrying heavy loads. Removable shockcord clips let you attach trekking poles and tool handles. Removable sleeping pad straps. Thermo-formed and perforated waffle-pattern shoulder straps and hipbelt save weight and enhance breathability. This lightweight daypack is designed for one-day adventures and trail running body hugging yet nonrestrictive for a full range of motion. Welded front stretch pocket is ideal for stashing shovel blade, helmet or jacket. Zippered panel-loading design allows easy access to the pack's contents.


Run or hike far, fast and fully-equipped with this lightweight Atmos 25 pack from Osprey. Ideally designed for adventure races and fast ascents, the Atmos 25 has full-length panel access so you can find what you need with minimal search time. 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 25 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 fit and function are just as important as pack weight, Osprey's Atmos 25 is everything you need in a durable and well-designed day pack.
