This is a Grivel Air Tech New Classic (strap-on type) 12-point crampon. It can be attached to mountaineering boots without welts. There are scratches and scuffs from use. Metal frame: Some rust and blade wear. Please purchase only if you understand that this is a used item and accept the scratches and dirt. The crampon accordion will be sent attached. I will also include a Montbell bag that I personally used to store the crampons. There is no box or instruction manual. Thank you for looking.
