The Petzl Antisnow (Antibottes) for Irvis crampons is a simple add-on designed to stop snow from packing under your crampons during winter trips. It slips onto the front points of Irvis crampons to help you maintain consistent traction in soft or wet snow without frequent clearing.
Made from dual density polymer, these antisnow devices combine a firmer core for staying securely in place with a softer outer layer that flexes around crampon bars. That blend of materials means they resist abrasion on rocky approaches while still conforming neatly to your crampons. Supplied as a pair, they’re easy to fit and can save you time and effort on snow-packed terrain by keeping buildup to a minimum.
