Combining high-tech, ultralight performance with the Alpride E2 Airbag System, the SCOTT SCO Pack Patrol Utralight E2 25 Kit is perfect for all of our ventures into the backcountry. The lightweight construction utilizes incredibly tough, waterproof Dyneema material to keep our gear protected as we haul up the skin track. The pack is feature-rich, with diagonal ski carry, stowable helmet carry, ice axe attachment points, and a dedicated avalanche tools pocket for peace of mind in variable terrain. The Alpride E2 takes two AA batteries so we can recharge on the mountain without hauling extra power supply, and the supercapacitor technology ensures that the charge and performance don't diminish in frigid temperatures.
