Description A high degree of shock absorption and breathtaking ventilation The outer shell in thermoplastic resin optimally limits the risk of perforation in the event of a fall. The inner shell, made of expanded polystyrene, damps and distributes the force of the impact over the entire helmet. Thanks to its front vents and rear outlets, this helmet provides optimum ventilation. Unparalleled comfort! The new one-piece, and removable, inner can be washed and replaced if needed. Its soft and fluffy fabric has received an antibacterial treatment. Maximum safety thanks to exemplary stability! The Twin Lock System (TLS), the patented rigid chinstrap, has been completely redesigned to provide maximum stability and hold, previously exclusively the preserve of motorcycle helmets. The chinstrap in thermoplastic resin provides extended protection for the neck as the area covered is greater than that with customary helmets. The reinforcement that the chinstrap provides to the shell increases the resistance in the event of a side-on impact. The new Fidlock magnetic closure can be opened and closed quickly with one hand, which makes it much easier to use. The flexibility of the TLS provides additional comfort as it adjusts to the shape of each persons head. Technical description: The range of GPA helmets complies the draft standard EN1384-2017.
