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. We took everything that the S-Works Prevail II was doing right & did it even better. One of the greatest benefits resulted from the removal of a total of seven foam “bridges” from the center & 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 & the cooler you remain—it’s called “convective heat transfer”. This all adds up to the coolest helmet we’ve ever made. The new 5th Dimension Cooling System with its redesigned patented aramid-reinforced skeleton provides internal EPS support allowing for 20% larger vents with deep internal channels & aligned exhaust ports. Our ultralight & supremely comfortable version of MIPS MIPS SL has only gotten better. We’ve added perforations along with a ripstop mesh to maximize breathability & performance. With MIPS SL we’ve essentially integrated MIPS technology within the helmet padding itself. MIPS SLs minimalist watchband attachment system provides 10 to 15 millimeters of rotation in every direction & offers the same brain protection benefits as other versions of MIPS while also ushering in a new level of comfort & weight savings. Patented Energy Optimized Multi-Density EPS construction helps to manage impact energy. Ultralight Mindset Hair Port II micro-dial fit system with height adjustability for the perfect fit. Thin soft & lightweight 4X Dry Lite webbing won’t stretch out with sweat or water. Tri-Fix web splitter improves comfort & ease of strap adjustments while an in-strap webbing system delivers ultralight construction & security. Five Star Virginia Tech Helmet Rating ™— Virginia Polytechnic Institute & State University awarded the helmet its highest rating of five stars. This helmet is ANGi fitted & comes with the ANGi crash sensor pre-installed
