No expense has been spared with 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, light-weight splitboard binding. Karakoram reduced weight by using stronger and lighter materials such as grade 5 titanium hardware and hollow pins, and increased response with a new C4 Carbon highback. The Prime-X sets a new standard for backcountry snowboarders. Travel lighter, travel faster, ride harder.
