The Black Diamond Camalot has been the go to camming device for more than a decade. So how do you make it better' You give it an even bigger expansion range, you make it 30% lighter than before, and you add a thumb loop to make one handed placements seriously easy. The new design is so good that two of the half sizes were eliminated because they're no longer needed. The Camalot C4s have won award after award and have become the standard for any serious climbers building up a rack. Whether you're freeing big walls in Yosemite or sending splitters in the Creek, this cam has everything you need.
