The Details

With Specialized's S-Works Prevail II Vent Mips road cycling helmet, the brand have increased the total vent surface area by 20%, which in turn has more than doubled the cooling capacity of this model with the last.

Ideal for the hottest climbs in the most humid conditions you can be assured that the S-Works Prevail II Vent is keeping you cool and letting you perform at your best.

The carbon fibre and aramid-reinforced skeleton provides support, and also allows for large vents with deep internal channels and aligned exhaust ports. Added to that is a perforated MIPS SL pad kit for breathability. The ANGi Crash Sensor can be combined with Specialized's iOS or Android app, to detect a crash and send a text message to specified contacts in your phone. It also syncs with their app and Strava to provide GPS-based activity tracking.

 

  • New 5th Dimension Cooling System
  • Patented Energy Optimized Multi-Density EPS construction helps to manage impact energy
  • Perforated MIPs SL pad kit for breathability

 

Our Verdict

The new S-Works Prevail II Vent cycling helmet with MIPS and an ANGi crash sensor is the next evolution of Specialized's 'Cooler Heads Prevail' approach to helmet design.
