GPA 4S First TLS Shiny women's riding helmet

Created for optimum safety, the 4S helmet is made up of 4 layers that provide successive shock absorption and improved resistance to lateral compression.
The 4S breakdown:

• 1S: outer shell designed to absorb a first part of the impact. It 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 absorb the impact energy and absorb it.
• 3S: this is the main shell, reinforced with fiberglass for rigidity and protection. Shock is already absorbed when it is reflected at 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 reduce the risk of perforation. Thanks to its front openings and rear extractors, this helmet offers optimal ventilation.
• INSIDE SHELF: EPS shock-absorbing element made of 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.
• VISOR STRAP: made of thermo-composite elastomer resin, which gives it a certain flexibility in accordance with the required standards.
  Why choose the TWIN LOCK SYSTEM chinstrap?
• Made of thermo-composite resin and injected fiberglass, it is extremely hard-wearing.
• Unsurpassed stability and support
• Optimal safety with greater protective coverage, especially on the back of the neck
• Thanks to its rigidity, the entire helmet is reinforced in the event of crushing, as on motorcycle helmets.
• Significantly improved fields vision
• Greater comfort: for soft touch contact with the rider's skin, removable foams have been added to the TLS's
  temples.
• No more problems with ill-fitting chinstraps: the Twin Lock System's size is adapted to the helmet's shell
  for optimum fit!
• The Fidlock magnetic buckle makes fastening easy and fluid.
