The Levity and Lumina Series are made for backpackers who celebrate base pack weights and half-length toothbrushes. Osprey's goals were never about achieving a number on a scale, but instead, finding a solution that is not only light, but effectively carries the loads it’s tasked with. We combined lightweight materials with durable outer fabrics to minimize pack weight without sacrificing durability. No pack of this weight comes close in comfort, ventilation or load-carrying ability. Pick it up, put it on, and head out on streamlined weekends or the most committing thruhikes.
