With features from several of POC’s award-winning helmets, and a unibody shell construction first introduced in POC's groundbreaking Octal road helmet, the Tectal Race SPIN provides protection and ventilation on a previously unseen scale for mountain bike riders. With the inclusion of SPIN (Shearing Pad INside), POC's patent-pending silicone pad technology system, the helmet further builds on the whole-helmet approach to design and construction in order to deliver superior levels of comfort, fit and performance. Other safety features include an aramid bridge system for improved structural integrity and a reinforced EPS liner. The unibody shell construction supports the integrity of the helmet while ensuring the weight remains low. And with ventilation optimized and evaluated through wind tunnel testing, the Tectal Race SPIN delivers lightweight, reliable protection that will keep you cool headed as you push your boundaries on the trail.
