We run the S-Works Prevail 3 MIPS Helmet because it keeps us cool as we explore new roads. Specialized designed the Prevail 3 with thru-air channels that increase the surface area of ventilation by 24. 5% from the previous Prevail 2 helmet. MIPS Air Node technology provides superior protection, using a low friction layer that is designed to reduce rotational forces to the head upon impact.
