Blue Ice Harfang crampons are ultralight (377g per pair without ABS) and hyper compact, 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. The heel pivot is equipped with a micro adjustment dial to fine tune the crampon on the shoe. It is an automatic and semiautomatic crampon, which adapts to all ski touring boots, as well as mountaineering shoes with rigid and semi-rigid sole. Supplied with ABS. They are delivered in their bag which can be attached to your belt or snap into the backpack. You have your crampons close at hand without the clutter, as they are very compact. And in the bag, they take up a minimum of space ...But it is on your feet that they work the best !
