For your multi-day backpacking adventures the Osprey Atmos 65 Backpack offers a lightweight frame for packing all the gear you need in comfort. A mesh back panel allows airflow to keep you cool through long hours on the trail and with AirSpeed suspended shoulder straps and soft foam harness and hip belt this backpack rides smooth over uneven terrain. With plenty of storage and attachment loops for all your essential gear and a comfortable load range up to 50 lbs you wont have to leave anything behind. Designed to tackle long hikes and multi-day trips the Atmos increases the contact area for a more uniform fit that limits hot spots. A LightWire alloy frame decreases weight and with additional cross struts creates a stable but flexible harness system that will get you and your gear out and back in comfort.
