Petzl's Sarken crampons are designed for difficult routes in the high mountains: steep snow and ice slopes, couloirs, gullies, and mixed climbing.

The Sarken is available with 3 types of binding systems:
SIDELOCK, for boots with front and rear sole overlaps (wire at front and rear); rapid-fastening lateral binding system, avoiding the encumbrance of a heel-bail.
SPIRLOCK, for boots with a rear sole overlap (wire at the rear, flexible binding at the front). Strap fastening system, avoiding the encumbrance of a heel-bail.
LEVERLOCK, for boots with a rear sole overlap. Heel bail with micrometric adjustment and wide adjustment range at the rear.
