The Specialized Sierra womens road cycling helmet offers serious protection in a stylish and great value package.
The Sierra is packed with features designed for comfort and protection including a Ponytail-ready HairPort SX fit system. This gives you micro adjustability and room for your hair for easy and accurate fitting.
A Tri-Fix web splitter improves comfort with easy strap adjustments for hassle free riding. Keeping you cool is the Specialized 4th Dimension Cooling System which connects deep vents at the front to exhaust at the rear. The system works to pull air through the lid and also wick away sweat for a more comfortable ride.
Specialized’s Sierra womens cycling helmet also comes with reflective webbing and decals to improve your visibility in poor light conditions - ideal for commuting.
