Specialized S-Works Prevail II Vent MIPS helmet

The coolest helmet Specialized's ever made

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. Specialized took everything that the S-Works Prevail II was doing right, and did it even better. One of the greatest benefits came from the removal of a total of seven foam “bridges” from the center and sides to create more effective ventilation channels. These expanded channels 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”. 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.

5th Dimension Cooling
The new 5th Dimension Cooling System, with its redesigned, patented, carbon fiber and aramid-reinforced skeleton, provides internal EPS support allowing for 20% larger vents with deep internal channels and aligned exhaust ports. Additionally, the new perforated MIPS SL pad kit keeps moisture moving and allows for even more breathability.

MIPS
This new ultralight and supremely comfortable version of MIPS, MIPS SL, has only gotten better. Specialized has added perforations, along with a ripstop mesh to maximize breathability and performance. With MIPS SL, the MIPS technology has been essentially integrated 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.

  • Tri-Fix web splitter improves comfort and ease of strap adjustments, while an in-strap webbing system delivers ultralight construction and security.


Certifications

  • EN 1078.
  • Five Star Virginia Tech® Helmet Rating™: Virginia Polytechnic Institute and State University awarded the helmet its highest rating of five stars.


Technologies

MIPS Brain Protection

MIPS is a low friction layer inside the helmet which allows the head to rotate relatively to the helmet in an angled impact. This substantially reduces rotational violence and the potential for damage to the brain. Collaborating with some of the world's leading neurosurgeons and experts, MIPS® has established that when you fall, your head most often hits the ground at an angle, creating a rotational shock to the brain. This rotational shock can cause strain in your brain. A helmet with MIPS® absorbs much of that rotational energy, offering you better protection. And if, against all the odds, you do fall vertically onto your head, a helmet with MIPS® will protect you just as well as an ordinary helmet.
