A light-weight, universal crampon. G10 is designed to meet the classical demands of general mountaineering. It is perfect for ski touring, trekking, or for women and children (whose small boots don't require many points underneath them). The crampons are fully adjustable by hand, without tools and one size fits all. G10 folds easily for transportation.
