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: this is the main shell, reinforced with fiberglass, elle providing rigidity and protection. The impact is already cushioned when it is reflected at this level
- 4S: the EPS pad finishes off the impact deceleration by crushing under the pressure of the impact, protecting the skull 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 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.
- VISOR: made from thermo-composite elastomer resin, which gives it a degree of flexibility in line with required standards.
Why choose the TWIN LOCK SYSTEM chinstrap?
- Extremely resistant, elle is made from thermo-composite resin and injected fiberglass.
- Unrivalled stability and support
- Optimum safety with greater protective coverage, especially on the nape of the neck
- Thanks to its rigidity, reinforcement of the entire helmet in the event of crushing, as on motorcycle helmets
- Significantly improved fields of vision
- Greater comfort: for soft-touch contact with the rider's skin, removable foams have been added to the TLS temples.
- No more problems with ill-fitting chinstraps: the size of the Twin Lock System is adapted to the helmet shell for optimum fit!
- Its magnetic buckle closure Fidlock makes fastening easy and fluid.
