A supportive backpack shouldn't mean compromising weight, and the Exos is here to prove it. The Exos 38, made with 100% recycled materials is a formidable featherweight for overnight expeditions, with a minimal capacity and the same capable feature set as its larger sibling. Highly experienced backpackers will appreciate industry-leading comfort and ventilation—without the weight it often adds—making it the perfect pack for lightweight overnights and slimmed down weekends. Still not svelte enough for you? Drop the removable floating lid and rely on the integrated FlapJacket instead. Plus, our refined AirSpeed suspension keeps you cool with maximum airflow between you and your pack, so each mile stays as comfortable as the last.
