Size Medium. The AntiGravity mesh suspension on the iconic Osprey ATMOS AG65 pack makes it soooo comfortable and provides added ventilation so your back doesn’t get gross and sweaty! Lots of extra pockets and compartment options add to the convenience of this pack including easy-to-use stretch mesh side pockets for water bottles, an internal reservoir sleeve for hydration packs and trekking pole stowaway attachment. It’s in great shape with one very little snag on the front mesh pocket that could be easily taped, sewn, or patched up. Perfect for both weekend getaways and week long adventures. Asking $250, retails new for $440.
