For the women's pack to carry when every ounce matters but you still need to count on your backpacking pack for a supportive carry, the Osprey Women's Eja 48 Pack - XS/S is just the ticket. Reach for the Eja 48 for the ideal mid-size ultra-light, with plenty of room to put in the miles, but not so much that you're tempted to overpack. Highly experienced backpackers will appreciate industry-leading comfort and ventilation—without the weight it often adds—making it an excellent pack for committing thru-hikes and ultralights like the AT or Colorado Trail. Need to trim some extra weight? An integrated FlapJacket takes the place of the removable floating lid in a pinch. Plus, the refined AirSpeed® suspension keeps you cool with maximum airflow between you and your pack, so each mile stays as comfortable as the last.
