Engineered for performance on both road and track, the Alpinestars S-R7 uses a multi-layer composite shell combining fibreglass, carbon and aramid fibres for excellent strength, impact absorption and penetration resistance. Its smooth aerodynamic profile reduces potential impact load points, while a collarbone cut-out helps minimise contact with the body during a slide. Alpinestars' patented A-Head helmet system allows adjustment of the helmet's height and angle for a personalised fit, while ten ventilation ports provide effective airflow throughout. Designed to deliver high levels of protection, comfort and performance.
