More Unobstructed Airflow

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. A 20% increase in the vented areas allows air to flow more efficiently throughout the entire helmet.

18% Faster Airflow = The Coolest Helmet We've Ever Made

Channeling Cool

The expansive channels of the S-Works Prevail II Vent 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. Yup, we’ve done the math.

q = hc*A*(∆T) - Convective Heat Transfer equation

The Pro's Choice

It’s no accident the world’s top pros choose the S-Works Prevail II Vent, it keeps them cooler so they can ride faster. Cooler is faster after all. At the biggest races around the world, the S-Works Prevail II Vent will be featured atop the coolest heads in the peloton.

Innovate or Die

Our engineers went back to the drawing board to completely redesign the helmet’s internal skeleton. Utilizing robotically spun Aramid ropes, we were able to increase internal strength and completely remove the foam “bridges” from the center and side vents to create the expanded ventilation channels.

Welcome to the Family

Cooler (really) is faster. We proved this last year with the S-Works Vent Shoe. Not only did it win a few races, but the substantially improved temperature regulation confirmed that we were on to something. So, we thought, why not put our heads together to develop more ways to keep riders cool under pressure?
