Built for ski touring and mountaineering, the Blue Ice Harfang Crampon features an excellent balance between weight, compactness, and performance with its Chromoly steel front rail and aluminum secondary/rear rails. Connecting the front and back rails with a central textile strap, you will feel the best position possible for your boots. While on the go, a micro adjustment dial on the heel pivot allows you to make quick fixes to your crampon without wasting any time.
