No expense has been spared. CNC machined completely from 7000 Series Space-Grade Aluminum and injection molded with Carbon Nyolite, the Prime-X is a featherweight beast. This is not a flimsy splitboard binding that took shortcuts to save weight. We reduce weight by using stronger and lighter materials such as grade 5 titanium hardware and hollow pins. Our new C4 Carbon highback features a progressive reinforcement profile: stiffness down low for leverage on turns, and flexibility at the top for comfort while touring and tweaking. The Prime-X sets a new standard for backcountry snowboarders. Travel lighter, travel faster, ride harder.
