Helmets have long been plagued by an unspoken rule: Light weight, ventilation, aerodynamics—pick two, there's your helmet.
When we set out to improve the original S-Works Prevail, we knew that we had our work cut out for us.
Cooler heads will always prevail. The new S-Works Prevail II Vent’s massive cooling power helps better regulate your body’s temperature to keep you cooler so that you’ll always be ready when your ride heats up.
When time is of the essence, no other helmet will get you from start to finish faster than the S-Works TT.
