Harfang crampons are the lightest crampons (377 g per pair without ABS) and the most compact on the market, designed for ski touring and classic mountaineering. With chromoly steel front rail, aluminum secondary and rear rails they offer an excellent balance between performance, weight and compactness. Our patented concept is based on a central textile strap that connects the front and back rails and allow it to mount it in the most suitable position based on the application or the geometry of the boots. One size fits all. Using a flexible strap linking system minimizes bulk and offers a real compactness. While offering remarkable precision and comfort compared to existing solutions. The heel pivot is equipped with a micro adjustment dial to fine tune the crampon on the shoe. It is an automatic crampon, which adapts to all ski touring boots featuring a toe welt, as well as mountaineering shoes with rigid sole and toe welt. Supplied with ABS.
