Riding Helmet 4S First Lady, Hybrid Glossy by GPA

Usage
Like every GPA helmet, the 4S has been developed with a focus on maximum protection. The 4S is a technological revolution with its 4 layers, providing optimal shock absorption and better resistance to lateral compression. Unmatched cushioning: The outer shell made of absorbing polymer absorbs the initial part of impacts through deformation. The second layer takes on the impact energy and absorbs it. The third layer made of fiberglass ensures the rigidity of the entire helmet to prevent lateral compression. The fourth layer is the polystyrene shell, which completes the impact deceleration by crushing under the impact, thus protecting the skull from head injuries.

An optimal ventilation system: Thanks to its numerous front and side openings and rear extractors, this helmet offers maximum ventilation. Unmatched comfort: The new one-piece and removable interior can be washed and replaced if necessary. The soft and fluffy interior is treated to be antibacterial. Improved neck protection and enhanced stability: The classic chin strap is replaced by a hybrid system. Unique to GPA. The rear part of the chin strap, located between the Twin Lock system and the traditional chin strap, is made of thermoplastic resin and integrated fiberglass fabric. The nylon fastening straps covered with synthetic leather are secured with a two-part buckle. Thanks to its rigid part at the back, which extends the shell, the hybrid chin strap guarantees greater protection and better stability of the helmet on the head. Its affordable price and design will also appeal to conventional riders.
