The Twister Full Face Helmet features an aerodynamic EIRT (Energy Impact Resistant Thermoplastic) external shell with a differentiated density EPS internal shell for impact protection. It includes breathable, hypoallergenic, removable and washable liners, along with a removable lower wind stop and nose guard. Ventilation is adjustable through chin vents, an upper shell vent, and a rear extractor. The scratch-resistant, rapid-release visor provides extra wide vision and is Pinlock-compatible, including an anti-fog film, while an internal sun shield offers added protection. The visor mechanism is tool-free for easy adjustment, and the retention system uses a quick-release micrometric buckle for a secure fit. The helmet is Bluetooth-ready for communication systems and meets ECE 22-05 safety standards.
