Specialized S-Works Prevail II Vent

We took everything that the S-Works Prevail II was doing right, and did it even better. One of the greatest benefits resulted from the removal of a total of seven foam *bridges* from the center and sides to create more effective ventilation channels. These expanded channels move air across your head 18% faster than the original Prevail II. The faster air moves across your head, the faster heat is whisked away from your head and the cooler you remain! it’s called *convective heat transfer*. This all adds up to the coolest helmet we’ve ever made.
