Keeping the head cool and safe

Cooler heads will always prevail, which is why the new S-Works Prevail II Vent is the coolest helmet Specialized has ever made. Its massive cooling power helps better regulate a riders body’s temperature to keep you cooler so that riders will always be ready when their ride heats up.


Specialized 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.

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 Specialized has ever made. Yup, they’ve done the math.

q = hc*A*(∆T)

Convective Heat Transfer Equation
q = heat transfer rate
hc = convection heat-transfer coefficient
A = exposed surface area
∆T = temperature difference

It’s no accident the world’s top pros choose the S-Works Prevail II Vent, it keeps them cooler so they can ride harder. The racing season is officially underway and the S-Works Prevail II Vent will be featured atop the coolest heads in the peloton. Keep a look out during the 2021 season to catch a glimpse of the helmet on professional cycling teams Legion of LA, SD Worx, Deceuninck – Quick-Step, and BORA-hansgrohe.

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

Cooler (really) is faster. Proved 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, they thought, why not put their heads together to develop more ways to keep riders cool under pressure?

The S-Works Prevail II Vent features the MIPS SL’s minimalist “watchband” attachment system, providing 10 to 15 millimeters of rotation in every direction while offering the same brain protection benefits as other versions of MIPS. Exclusive to the S-Works Prevail II Vent is a redesigned MIPS pad kit with perforated ripstop backing for improved breathability, creating a helmet with seamless comfort and unparalleled performance.
