Pezl was founded by the legendary and record setting caver Fernand Petzl in the 1940s, and it is now one of the biggest and best suppliers of technical hardware for rock climbing, mountaineering, and camping on the planet. From the world's most popular belay device the GriGri, to the lightest weight mountaineering helmet on the market the Sirocco 2, to the Nao+ headtorch, the first headtorch with Reactive Lighting technology, it's hard to say what Petzl are best at, because they're simply innovative in everything.
