Like a few other ski mountaineering oriented crampons on the market, it’s made with a steel toe piece and an aluminum heel. ![]() The Petzl Irvis Hybrid is a crampon designed to be packable and light, but still capable enough to climb some of the harder ice and rock that we might find on ski mountaineering routes. While the search for the perfect crampon continues, the Petzl Irvis Hybrid ticks a number of boxes and has left me very satisfied. With that exacting rubric in mind, I’ve spent the last four years testing the Petzl Irvis Hybrid crampon on ski mountaineering lines in the Sierra and beyond.
