Defender Bike Helmet

We've always loved Kask helmets for their superior comfort and quality, so we're happy to see they've entered the world of gravity mountain biking with the Defender full-face helmet. It features a full carbon shell with 18 large ventilation ports, making for a strong, lightweight, well-ventilated helmet with full ASTM downhill race certification. The chin guard provides comprehensive coverage, and uses a replaceable foam air filter that preserves airflow while guarding against dust and debris.
