When we set out to improve the original S-Works Prevail, we knew that we had our work cut out for us. How could we improve on the industry benchmark for fit, ventilation, and comfort? By listening to our riders—that’s how. Through this, we realized that there were a few aspects of the original Prevail II that needed to be changed, with the biggest request being for a lower-sitting design.

We've teamed up with MIPS researchers to introduce MIPS SL—a new, ultra-light, and supremely comfortable version of MIPS that's available exclusively on Specialized helmets. With MIPS SL, we've essentially integrated MIPS technology within the helmet padding itself. MIPS SL's minimalist "watchband" attachment system provides 10 to 15 millimeters of rotation in every direction and offers the same brain protection benefits as other versions of MIPS, while also ushering in a new level of comfort and weight savings.

We thought to ourselves, "thinking big shouldn't result in bigger helmets," so with the Prevail, we set out to prove that big ideas can come in smaller packages. It all starts with our patented EPS construction that relies on multi-density foam that's paired with a robotically woven, Aramid-reinforced skeleton. This comes with a reduction in the overall size, creating a smaller profile that fits lower down on the head for a better fit and safety.

It also has deep internal channels that are aligned from front-to-rear, so the air intake and exhaust are optimized for unparalleled cooling over the entire head. And in the Win Tunnel, we found these new designs amounted to six seconds saved over 40km when compared to a "standard" road helmet. Another standout feature of the S-Works Prevail II is the Gutter Action System that manages the flow of sweat, keeping it away from your eyes and dripping it off of the pads over your temple.

In the end, the S-Works Prevail II is the most complete lightweight race helmet we've ever made—perfect for hot, mountainous rides and flat, windy sections alike.
