4S Speed Air Hybrid Riding Helmet

GPA 4S Speed Air Hybrid Riding Helmet - Like every GPA riding helmet, the 4S helmets were developed with maximum protection as the focus. The 4S is a technological revolution with 4 layers which enable optimum shock absorption as well as better resistance to lateral compression. Challenge your limits while staying well protected by GPA safety legend. 

Unparalleled 4-layer damping technology: The outer shell, made of absorbent polymer, absorbs the first part of impacts by deforming. The 2nd layer takes up the energy of the impact and absorbs it. The 3rd layer, made of fiberglass, ensures the rigidity of the entire helmet to avert any lateral compression. The 4th layer is the polystyrene shell which completes the deceleration of the impact by crumpling under the impact, thus protecting the cranial vault from brain injuries.

An optimal ventilation system: Thanks to its numerous front and side vents and its rear outlets, this helmet offers maximum ventilation.

Unparalleled comfort: This new one-piece and removable liner is washable and, where necessary, can be replaced. The soft and fluffy inside has been given an antibacterial treatment.

Better neck protection and increased hold: The classic chinstrap is replaced by a hybrid system, an exclusive from GPA. A cross between the twin lock system and the traditional chinstrap, its rear part is made of thermoplastic resin and incorporated fibreglass fabric. Its nylon straps, covered with synthetic leather, fasten by means of a two-part buckle. Thanks to its rigid part at the back which extends the shell, this hybrid chinstrap guarantees greater protection and better hold for the helmet on the head. Its more affordable price and design will also win over the more conventional riders as well.
