The GPA Speed Air 4S is filled with top notch safety features. With 50 years of expertise in the design of helmets, GPA created the Redline 4S Collection following a patented principle that allows for a new level of shock absorption and better resistance to lateral compression. Helmets are traditionally made of two layers, a rigid shell and an EPS foam liner. The Redline 4S Collection of helmets are designed with 4 elements of safety instead of two.
We're riders ourselves, so we understand that helmet fitting is not always easy and can get a bit confusing. We would be happy to help you, please call or email us with any questions; we are your friendly neighborhood tack shop online.
