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.
