GPA Riding helmet 4S Speed Air, TLS matt

Challenge your limits

Like every GPA helmet, the 4S has been designed with maximum protection in mind. The 4S is a technological revolution with its four layers that allow for optimal shock absorption as well as better resistance to lateral compression.

Unsuspected damping

The outer shell in absorbent polymer absorbs an initial part of the impact by deformation. The second layer absorbs the energy of the impact. The third layer of fiberglass provides rigidity to the entire helmet to avoid lateral compression. The fourth layer is the polystyrene shell, which completes the deceleration of the impact by squeezing under the impact, protecting the cranial box from skull injuries.

An optimal ventilation system

Thanks to its numerous front and side openings and its rear extractors, this helmet offers maximum ventilation.

Unsuspected comfort!

The new one-piece and removable interior can be washed and replaced if necessary. The soft and fluffy interior is antibacterial treated.

Maximum safety thanks to unprecedented stability!

The Twin Lock System (TLS), the patented rigid chinstrap, has been completely redesigned to provide maximum stability and support previously reserved exclusively for motorbike helmets. Made of thermoplastic resin, the chinstrap offers extended protection of the neck, as the coverage area is larger than that of conventional helmets. The reinforcement provided by the shell's chin strap increases resistance in the event of a side impact.

The new Fidlock magnetic closure can be opened and closed quickly with one hand, which makes handling much easier. The flexibility of the TLS provides additional comfort as it adapts to the morphology of each individual.

The TLS chin strap is the trademark feature of the new GPA riding helmet collection.
