Eagle Creek Ranger Xe Backpack, 16 Liters

Small but mighty in its versatility and comfort, this pack carries only the essentials – and organizes them with zippered pockets inside and out. Ventilation built into the back panel and shoulder straps keeps you cool and dry. A dedicated pocket secures a hydration bladder, the hip belt detaches for non-technical use, and sustainability is tops, thanks to 100 percent recycled fabrics.
