Description
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. It 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, absorbs the energy of the impact to absorb it.
- 3S: the main shell, reinforced with fiberglass, provides rigidity and protection. The impact is already cushioned when it reaches this level.
- 4S: the EPS skullcap decelerates the impact 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, which absorbs and distributes shock waves.
- INSIDE FOAM (LINER): comfort foam coupled with soft, antibacterial fabric. Made in one piece, it is interchangeable and washable thanks to tabs that fit between the two caps.
- FRAME: made of thermo-composite elastomer resin, which gives it a degree of flexibility in line with required standards.
Why choose the TWIN LOCK SYSTEM chinstrap?
- Highly resistant, made from thermo-composite resin and injected fiberglass.
- Unrivalled stability and support
- Optimum safety with greater protective coverage, especially at the nape of the neck.
- Thanks to its rigidity, the entire helmet is reinforced 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 TLStemples.
- No more ill-fitting chinstraps: the size of the Twin Lock System is adapted to the helmet shellfor optimum fit!
- Its magnetic buckle fastening system Fidlock makes fastening easy and fluid.
