A helmet for ambitious free riders needs to be light, well ventilated, tough, comfortable and stylish. The SPINE has the lot. Its Infold construction makes it particularly lightweight and thanks to the additional edge protection it is extremely tough. The easy-to-use, one touch ventilation system is an outstanding feature. The ventilation can be opened or closed with a single hand movement - even during high-speed descents. The perforated ear pads make it easier to hear ambient sounds, and are made in a one-piece design with the lining to give maximum comfort. The entire interior can be removed for washing.
