The French manufacturer Petzl made its debut in the caving field, pioneering an innovative nylon-rope solution to progress through caves. Nowadays, its mission is of course gearing up other passionate explorers with equipment like the widely endorsed headlamps. It also provides climbers with helmets, pulleys, descenders, ascenders (see belay devices), carabiners (see carabiners and quickdraws) and harnesses. But innovation is not over yet with this company! The GriGri belay device, for example, was its idea.
