Winner of the exclusive Alpinist Mountain Standards award for lightweight crampons. At just 390 grams per pair, the XLC 390s are the lightest semi-rigid 12-point crampons in the world. Distinguished by a new manufacturing design that distributes force applied to a single spike across the entire platform making spikes less likely to bend or snap. Equipped with an automatic binding and constructed almost entirely from durable 7075 aluminum alloy.
