The new POC Obex Spin is a great helmet for any skier looking for protection and a sporty style. POC's patent-pending SPIN gives the helmet the ability to move relative to the head by shearing from the shell when an impact occurs so the force is not transmitted to the wearer. The In-Mold Construction with an EPS Liner is very lightweight. The ABS top shell has adjustable ventilation to keep air moving through the helmet if you wish to cool you down and prevent overheating on the mountain. Integrated Vents sit above the top foam of your goggles to prevent lens fogging. POC's Size Adjustment gives you the ability to fine tune the fit perfectly to match your head size and shape.
