Advanced construction for your safety
The helmet's shell is made of thermoplastic and comes in two sizes to better fit your head. Inside, there is an EPS core with five densities, designed to absorb impact energy in key zones. The lower part of the helmet has a special shape that helps distribute the forces of a fall away from the collarbone area. Secure fastening is provided by stainless steel double D-rings.
Comfort and inner lining
The helmet's inner lining is fully removable and washable, making it easy to maintain. The hypoallergenic material is treated with Silverplus® technology, which uses silver ions to prevent the growth of bacteria and odours. For emergencies, the helmet is equipped with an Emergency Release System (ERS) for the cheek pads. This allows rescuers to easily and safely remove the helmet from an injured rider's head without risking further injury to the cervical spine. The helmet is also ready for intercom installation.
Ventilation and practical details
The ventilation system provides airflow through several intake and exhaust ports and is particularly suitable for warmer weather. It features a quick-release visor system, which automatically detaches if hit at a certain angle. This system reduces the risk of injury from rotational forces. The helmet is ready for hydration pack tube routing, so you can drink while riding. A wide 26mm polyester chin strap ensures a secure fit.
