OSPREY Women’s Eja 58 Liter Backpack Size Extra Small (Fits Torso 14-17”) When every ounce matters—but you still need more than just a sack with shoulder straps—the women's Osprey Eja 58 pack offers a supportive carry when resupplies are few and far between. See pic for description and specs. Good Condition. Used a generic zipper pull on top compartment of the backpack (2 extras given).
