With space age design and materials like titanium and carbon, Burton’s lightest weight binding cuts right to the chase. The design direction for the X-Base was simple: dig deep in Burton R&D to build the strongest and lightest binding with the absolute best ingredients. The result is a binding with focused performance down to the tiniest details, including a carbon composite Ultra Hi-Back and a lightweight single-component carbon fiber/nylon composite baseplate for the ultimate blend of foot-hugging comfort and response. Cushioning is included in all the right places for the ultimate balance of plush and precision. The EST® model is compatable with boards featuring The Channel® mounting system for the ultimate in feel, flex, and adjustability.
