GPA 4S Speed Air TLS

Pushing back the limits
Like all GPA helmets, the 4S has been designed for maximum protection. The 4S helmet represents a technological revolution, with its four layers providing remarkable shock absorption and improved resistance to lateral compression.

Incomparable shock absorption
The outer shell, made of shock-absorbing polymer, absorbs the initial impact by deforming. The second layer attenuates and absorbs the energy of the blow. The third layer, made of fiberglass, ensures the rigidity of the helmet as a whole, preventing lateral compression. The fourth layer is the polystyrene shell, which slows down the impact of contusion, protecting the skull from injury.

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

Unrivalled comfort
The new one-piece removable inner liner can be washed and replaced as required. Soft and cushy, it is treated against the growth of bacteria.

Optimum safety thanks to unrivalled stability
The patented Twin Lock System (TLS) rigid chinstrap has been completely redesigned to offer optimum stability and support previously reserved for motorcycle helmets. The thermoplastic resin chinstrap offers additional neck protection thanks to a larger covering surface than on conventional helmets. The chinstrap reinforces the skullcap and increases its resistance to side impact. The new magnetic closure Fidlock opens and closes quickly with just one hand, making handling much easier. The flexibility of the TLS system offers greater comfort by adapting to individual body shapes. The TLS chinstrap is a registered trademark of the new GPA riding helmet collection.

Foam is always included with the purchase of a GPA helmet.
