GPA Speed Air 4S helmet from the Redline Collection by GPA is filled with top notch safety features. With 50 years experience in the business and following a patented principle, the Reline generation of helmets allows for a new level of shock absorption and double the safety. Helmets are traditionally made of two layers, a rigid shell and an EPS foam liner. The Redline Collection of helmets are designed with 4 elements of safety. The 4S, whose sandwich superposition allows for remarkable damping, and better resistance to lateral compression.
The 4S breakdown
Outer shell designed to absorb the first round of shocks, It is made of absorbed polymer adapted to be deformed on impact.
The interface, in case of a crash, will absorbed the impact energy to reduce it.
This is the main shell, reinforced in fiberglass it provides rigidity and protection. The shock has already been dampened after passing through this level.
The is the SPE foam liner that finished decelerating the shock by crashing under the pressure of the impact and thus protecting the skull and minimizing the risk of cranial lesions.
Additional GPA Helmet Liners also available!
