GPA Hybrid air riding helmet 4S Speed

Created for optimum safety, the 4S helmet is built around 4 layers that provide successive shock absorption and improved resistance to lateral compression.
The 4S breakdown:
- 1S: outer shell designed to absorb a first portion of impact. Elle is made of an absorbent polymer and designed to deform under impact
- 2S: in the event of an impact, this interface, designed in an elastomer developed for Formula 1 racing, will take up the energy of the impact to absorb it.
- 3S: the main shell, reinforced with fiberglass, elle provides rigidity and protection. The impact is already cushioned by the time it reaches this level
- 4S: the EPS pad finishes off the impact deceleration process by crushing under the pressure of the impact, protecting the skull and minimizing the risk of head injuries
- EXTERNAL BODY: injection-molded in thermo-composite resin to limit the risk of perforation. Thanks to its front openings and rear extractors, this helmet offers optimum ventilation.
- INSIDE SHIELD: EPS shock-absorbing element in variable-density expanded polystyrene that absorbs and distributes shock waves.
- INSIDE FOAM (LINER): comfort foam coupled with soft, antibacterial fabric. Made in one piece, elle is interchangeable and washable thanks to tabs that fit between the two caps.
- FACE STRAP: made of thermo-composite elastomer resin, which gives it a degree of flexibility in line with required standards.

- For fans of the soft chinstrap
- Better support and protection thanks to its extension on the back of the neck
- Maximum comfort thanks to the new interior
