S-Works Prevail II Vent Helmet

Cooler heads will always win. And staying cool in the heat of a race is crucial. We've taken everything we've gotten from the S-Works Prevail II and improved it. One of the biggest benefits of the S-Works Prevail Vent comes from removing seven foam bridges from the center and sides to create more effective ventilation channels. Airflow is 18% faster than the Prevail II, so heat is dissipated sooner. This is the coolest helmet we've ever made.
• The new 5th Dimension Cooling system features a patented design with an updated internal Aramid and carbon fiber structure, providing the necessary EPS support for the large vents, deep internal channels and aligned rear exhausts – thus doubling the cooling capacity, and increasing the openings by 20%. The new perforated MIPS SL pads are breathable.
• Our version of MIPS, MIPS SL, is very light and comfortable. We've also added perforations and a tear-resistant material to further improve ventilation. MIPS SL means integrating MIPS technology into the padding. The minimalist attachment method provides 10 to 15 mm of rotation in each direction, providing as much protection as other versions of MIPS, only it's more comfortable and lighter.
• Dual density EPS construction to optimize impact management.
• Mindset Hairport II: Lightweight vertical adjustment system with dial for a perfect and comfortable fit.
• The thin, soft and lightweight 4X DryLite material the straps are made of won't fray from sweat or water.
• Tri-Fix device to simplify strap adjustment.
• Virginia Polytechnic Institute and State University Five Star Rating: Top marks.
• The sealing system is designed for the integration of an ANGi sensor.
• The ANGi sensor, available for purchase separately, gives you peace of mind—when paired with the Specialized Ride App, the sensor detects falls and sends a text message to selected contacts on your phone. The sensor syncs with the app and STRAVA® to provide GPS-based activity tracking.
