Exos 38 - Men's



When every ounce matters but you still need a backpack that's more than just a sack with shoulder straps, the Osprey Exos 38 makes for an excellent ultralight companion. Highly experienced backpackers will appreciate industry-leading comfort and ventilation—without the weight it often adds—making it the perfect pack for committing thru-hikes and ultralights like the AT or Colorado Trail. Need to slim things down even further? Remove the floating lid and use the integrated FlapJacket to protect your gear inside. Plus, Osprey's refined AirSpeed® suspension keeps you cool with maximum airflow between you and your pack, so each mile stays as comfortable as the last.

100% recycled materials.
