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 by the time it reaches 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!- Closing with the magnetic buckle Fidlock makes fastening easy and fluid.
