Made for alpine tours and long days in the backcountry, the robust Ortovox Peak 45 Backpack is constructed with an extremely tear-and abrasion-resistant nylon 420D Manstar that proves its worth when put to the test. Broad, padded shoulder and hip straps distribute the weight of the load evenly between the shoulders and hips, keeping the ride extra stable over rocky terrain, while the diagonal ski fastener, snowboard and snowshoe attachment, ice axe and hiking pole fastening loops, and crampon fastening allow you to bring all of your gear for the mountain adventure with reliable security. The hydration sleeve ensures you won't go thirsty, and a signal whistle combined with an illustration of alpine emergency signals under the lid help you out if you get caught in a tough situation. Plus, the Swisswool Full Contact back system offers unique moisture and microclimate management to make your back feel comfortable and dry when you're hauling a heavy load. The full contact back fits closely to your body and delivers optimum weight distribution, while its design consists of two aluminum struts that provide high stability and guarantee great comfort.
