The Supreme 70 shin guards use NIKE X-sorb knee cap protection for maximum coverage on the ice. The NIKE air unit in the knee provides a cusion between the body and the shell. These shin guards come with a full calf wrap with vent armor foam and a shin sling. The perforated panels allow for lightweight breathability. An anchor wrap strap across the calf and knee along with a calf closure strap provide a secure fit.
