Hybrid air riding helmet 4S Speed

Designed for optimum safety, the 4S helmet features 4 layers for successive shock absorption and improved resistance to lateral compression.
The 4S breakdown:
- 1S: outer shell designed to absorb the first part of impacts. Elle is made of an absorbent polymer and designed to deform under impact.
- 2S: in the event of an impact, this interface, made from an elastomer developed for Formula 1 racing, will absorb the impact energy and absorb it.
- 3S: the main shell, reinforced with fiberglass, elle provides rigidity and protection. The impact is already cushioned when it reaches this level.
- 4S: the EPS padding decelerates the impact by crushing under the pressure of the impact, protecting the cranium and minimizing the risk of head injuries.
- EXTERNAL SHIELD: 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, which absorbs and distributes shock waves.
- INSIDE FOAM (LINER): comfort foam coupled with a soft, antibacterial fabric. Made in one piece, elle is interchangeable and washable thanks to tabs that fit between the two caps.
- VISOR: made of thermo-composite elastomer resin, which gives it a degree of flexibility in line with required standards.
