The Petzl Vasak LeverLock Universal is a classic all-mountaineering crampon, designed for winter climbing, glacier travel and snow couloirs.

The thinner frame helps reduce the weight, the horizontal front points allow good penetration and the LEVERLOCK UNIVERSAL bindings make them compatible with all hiking and mountaineering boots with rear welts; the components (FIL or FLEX) make them adaptable to all types of boot toe (with or without welts). The Petzl Vasak is a great all-around, general-purpose crampon.
