The lightest crampons in the world and the go-to crampons for competitive ski mountaineering. The patented heel is designed for rapid attachment with the fastest A/T boot models typically made for Dynafit® or similar style lightweight backcountry bindings. The Dyneema® linking strap reduces weight even further and allows the crampons to be folded onto themselves for packability. Solid aluminum linking bars are also included for a more rigid fit if desired. Note: due to the decreased size of the front platform, we recommend this crampon for boots up to size US 10/European 44. For larger boots, we recommend the XLC 390.
