A long-time favorite among AT thru-hikers and fast-and-light backpackers, the Atmos 50 combines both durability and lightweight performance. A redesigned harness and adjustable hipbelt now provide even better comfort and fit.
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 tensioned backpanel to provide the ultimate in support, weight distribution, flexibility and comfort. A sliding sternum strap and load-lifter straps allow you to fine-tune fit with on-the-go adjustments. Accommodating backpackers of different heights, the Atmos 50 is available in your choice of sizes. The Medium Atmos 50 fits torsos ranging from 18"-20.5" and the Large is designed for torso lengths that exceed 20".
To further ensure that the Atmos 50 fits like a glove, each hipbelt offers integrated adjustability that can extend the "wrap" of the supportive padding. This design allows for customized fit that ensures proper support and range of motion.
Designed to comfortably carry 30-40 pounds of gear, the top-accessed Atmos 50 lends versatility for outings ranging from overnight trips to fast-moving, light-packing extended backpacking trips. The Medium size offers 3051 cubic inches of storage capacity and the Large Atmos 50 has a 3234 cubic inch capacity.
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 sleeping bag compartment 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 high tenacity twill nylon and 100D high tenacity mini-ripstop nylon, the Osprey Atmos 50 is available in your choice of colors.
