A well cooled head always performs better. The new S-Works Prevail II Vent helmet helps better regulate your body temperature keeping you cooler on all your rides. We’ve taken everything the S-Works Prevail II did well, and made it even better. One of the biggest benefits was the elimination of a total of seven central and lateral connecting bridges, creating wider and more efficient ventilation channels. We increased airflow 18% more than the original Prevail II. The faster the air flows through the head, the faster the ventilation. This is thanks to more efficient convective heat transfer, which translates into the coolest helmet we’ve ever made.
