DESCRIPTION

Trango Big Bro climbing protection is built with an expandable tube chock design to protect your scared, groveling carcass when cracks grow to offwidth and squeeze-chimney sizes. Get the weight off your shaky fist stack, stick a Big Bro in the crack, push the button to extend it to the right size, and twist the sleeve to lock it in place. Since Big Bros resist pull in any direction, they're nearly impossible to accidentally dislodge as you climb past. These unique protection pieces are lighter and easier to rack than similar sized cams, and they're the only hope for pro once you start climbing into chicken-wing sizes.
