65 L hiking backpack built for multi-day treks, with a ventilated AntiGravity suspension system for outstanding carrying comfort even under a heavy load. It offers extensive practical storage, an integrated raincover, trekking pole attachments and a sleeping bag compartment — everything you need for a well-equipped multi-day adventure.
The Osprey Atmos AG 65 men's hiking backpack is designed for multi-day treks, week-long hikes or outings with a heavy load. With its 65-litre capacity, it carries everything you need to sleep, cook and move comfortably over long distances.
Its standout feature is the AntiGravity suspension system. This design wraps around your back and hips via a suspended 3D mesh, delivering excellent load distribution and airflow. The Fit-on-the-Fly harness and hip belt offer precise adjustment to suit a range of body shapes, reducing pressure points on the trail.
The Atmos AG 65 features extensive storage designed for multi-day travel. It includes two large side water bottle pockets, two zipped hip belt pockets, a reinforced front pocket, a sleeping bag compartment with removable divider and an internal sleeve for a hydration reservoir. Zipped side access points also make it easy to reach the main compartment without unpacking everything.
This pack is also equipped to handle changeable mountain or bivouac conditions. The integrated raincover protects your gear in wet weather, while Stow-on-the-Go trekking pole attachments, ice axe loops and sleeping mat straps make it easy to carry external equipment. It is made with 100% recycled materials and a PFC-free DWR-coated waterproof cover.
