Description
Description
The S-Works Prevail 3 helmet is perfect for riders who value the comfort and climate control offered by superior ventilation. It's the ultimate all-purpose helmet that excels in hot conditions, strenuous climbs, and mountain stages.
In a relentless pursuit of venting limits, we eliminated the center “bridges” from the foam that block air from the center, effectively creating “channels” that increase ventilation surface area by 24.5% over the S-Works Prevail II Vent. The all-new S-Works Prevail 3 has the largest venting area of any helmet we’ve ever made.
When a helmet sustains an impact, its job is to dissipate the energy generated. The conventional approach is that more foam (EPS) means better energy management. We've rewritten the book on cycling helmet design by going beyond the foam. Aramid cables run through the helmet and are anchored to the carbon fiber side panels. Upon impact, AirCage* technology acts like a suspension bridge and is designed to distribute localized forces throughout the helmet.
The occipital adjustment allows for a personalized fit, and the helmet angle can also be adjusted for compatibility with glasses. The TriFix system now has thinner straps to prevent irritation. The Mindset micro-adjustment system is very lightweight and provides even better grip for on-the-fly adjustment while riding.
MIPS Node Air technology is integrated into the padding with a thin layer designed to dissipate rotational forces. Perforations have been added to further improve comfort and performance.
• The new AirCage improves airflow. (Patent-pending technology)
• Fully wraparound polycarbonate shell for durability and a premium finish.
• MIPS Air Node is the most ventilation-oriented MIPS solution.
• Adjustable Tri-Fix increases comfort with a personalized fit.
• Occipital base adjustment optimizes comfort and compatibility with glasses.
