Product Highlights
Updated for 2009! A favorite among Appalachian Trail thru-hikers and fast-and-light enthusiasts, the award-winning Osprey Atmos 50 combines both durability and lightweight performance. A redesigned backpanel improves upon the Atmos 50’s already trail-tested load-carrying capability.
Osprey's AirSpeed Suspension system equips the Atmos 50 with weight-carrying efficiency and breathability. A lightweight aluminum frame works in tandem with twin titanium struts and a 3D tensioned backpanel to provide the ultimate in support, weight distribution, flexibility and comfort. Thermoformed and perforated waffle foam is used in the Atmos 50's harness and hipbelt to further combat heat build-up. The hipbelt further enhances fit by using Osprey's ErgoPull closure that draws tension along the top and the bottom of the belt. A sliding sternum strap and load-lifter straps allow you to fine-tune fit with on-the-go adjustments. To make certain that hikers get the ideal fit, the Atmos 50 is available in three different sizes. The S Atmos 50 accommodates torsos less than 18.5" in lengths, the M accommodates torso lengths ranging from 18"-20.5" and the L is designed for torso lengths that exceed 20".
Designed to comfortably carry 30-40 pounds of gear, the Atmos 50 lends versatility for outings ranging from day hikes to fast-moving, light-packing week-long adventures. The S Atmos 50 offers 2800 cubic inches of storage capacity and the M and L sizes offer 3000 and 3200 cubic inches, respectively. The main packbag has full top access dual front pockets are accessed through welded weather-resistant zippers. A welded, stretch woven Nylon pocket on the front of the pack allows you to stash extra layers or other gear. A pocket located inside the floating lid of the Atmos 50 provides yet another organizational option. Side compression straps help you cinch down your load and also serve as lash points for additional gear. Stretch woven side pockets are the perfect place for stashing water bottles or other smaller items.
Other features found on the Atmos 50 include integrated trekking pole loops and removable straps located in front of the pack that securely stow sleeping pads. An internal lined sleeve and dual exit ports combine to make the Atmos 50 hydration compatible. Zippered mesh pockets on the hipbelt keep snacks and essential items in easy reach.
Constructed of lightweight, durable 210D Twill Velocity Cordura and 160D x 210D Window Ripstop Cordura, the Osprey Atmos 50 is available in your choice of color options.
