Gym, home crag, or cabled route, the Petzl Corax Sm'D Grigri Kit is ready for it all. The versatile harness is easily adjusted for slim indoor layers or bulkier winter climbing layers, while its Frame technology evenly distributes weight across the waist and legs for optimal comfort whether we're holding our partner at the crux or hanging at our own crux. When giving our partner a catch, the auto-blocking belay device saves our break hand by relieving some of the pressure, and the compact 'biner ensures the Grigri is secure to our harness thanks to its auto-locking gate.
