True to form, CAMP USA has created the XLC 490 – the world’s lightest, strap-on, 12-point crampon! Thermoplastic toe and heel harnesses with secure nylon straps allow this crampon to securely fit nearly all footwear from trail runners, approach shoes, hiking boots, mountain boots, and ski boots. These are made from aluminum with a 3-dimensional, stamped frame. This increases strength and performance. Aluminum crampons are not designed for use on steep ice or rocky terrain, but on firm snow as encountered on the Pacific Crest Trail in June or on snowy mountain slopes in winter, spring, and early summer, these crampons can do it all, and allow you to keep your pack and your feet as light as possible. A Sierra Mountain Guides Favorite!
