The Eiger 42 is a durable, lightweight mountaineering backpack for longer treks that can carry all the gear you need at hand on the outside and stow everything else on the inside, while not feeling clumsy on the ascent. From first ascents to more intense expeditions, you'll be ready, thanks to features like a fully removable cinch-top lid, hip belts, framesheet, and compression straps with ski-edge reinforcements. The abrasion-resistant nylon can handle a strenuous trek while the molded back panel prevents snow from accumulating. Dual tool/pole attachments keep poles, ice axes, and other tools accessible when you need them and organized when you don't. Exterior bottle holders made from the body fabric of the pack won't stretch out.
