Removable lens system: The removable lens system offers replacement lenses with different colours and visible light transmissions (VLTs) that are suitable for different weather conditions and personal preferences when skiing, snowboarding or doing other winter sports. Ventilation and frameless design: Reduces fogging and optimises the flow of air through the lens. Ski goggles provide a gentle airflow system that quickly and effectively circulate fresh air and exhaled air moisture. The large, spherical, frameless lens provides a truly unobstructed and clear view of the slopes. Helmet compatibility: Extra long elastic band for compatibility with any helmet. The perfect goggles for men, women and teenagers. Compatible with glasses: Lots of space inside. The googles fit over most prescription glasses. Comfortable and perfect fit: The triple layer, high-density and soft shape is tightly attached to the frame to keep you warm on the mountain and cut wind.
