The Petzl Irvis Leverlock Universal is a lightweight and compact 10-point crampon, designed for ski touring and glacier travel.
Designed with a thinner frame that helps reduce the weight, the Petzl Irvis Leverlock Universal Crampon has two wide front points that allow good penetration. The Leverlock Universal bindings are compatible with all hiking and mountaineering boots with rear welts, and the components (FIL or FLEX) make them adaptable to all types of boot toe (with or without welts). The Petzl Irvis crampons are ideal for where you need a lightweight, simple system for use in variable conditions.
