Helmet Arai Quantum ST Puro White. The new Quantum ST is the successor to the popular model Quantum. It is the ideal companion for bikers sport-touring that requires a perfect combination between performance and comfort. Account with the technology of the helmet top of range (RX-7 GP) and with a new outer shell ScLc (Super complex Laminate construction), which is 40% stronger than the fiber glass standard. The new shell offers significantly more space around the chin area for greater comfort and ventilation on long journeys. Another innovation is the FCS (Facial Contour). The cushioned FCS offer an effect “dock” that allows you to wear the helmet more easily. Thanks to the FCS, the cushioned cover best the area below the jaw and the cheekbone area instead of the area of the cheeks (like most helmets). Although the fit feels looser, the FCS offers a secure support in a wider area providing greater stability and comfort with minimal pressure. The new quilted sides offer a more personalised fit, thanks to the "Peel Away". The Quantum ST has interior Dry Cool (removable and washable) and an efficient ventilation system with front air intake and extractors to the side and rear for optimum air circulation and maximum comfort. In addition, it incorporates screen clear Max Vision SAI, pinlock anti-fog system for emergency opening and closing of double ring. Note also that the Quantum ST meets the standards ECE 22-05 and SNELL M2010 standard, a number of features that until now only passed the RX-7 RC and RX-7 GP.
