The Petzl Vasak are classic mountaineering crampons designed for uses from glacier travel to snow couloirs. They have a thinner frame which means they are lighter than regular crampons. 

 

Available with either Leverlock Universel or Flexlock bindings so as be able to attach to all types of boots, with or without front and rear welts. An Anti-Snow system is included with the crampons which limits snow build up. Horizontal front points ensure solid purchase in hard snow.
