GPA Riding Helmet 4S First Lady TLS

• like every GPA helmet, the 4S has been designed with maximum protection in mind
• the 4S is a technological revolution with its 4 layers that allow optimal shock absorption and better resistance to lateral compression
• unrivalled shock absorption
• the outer shell made of absorbent polymer absorbs a first part of the impact through deformation
• the 2nd layer absorbs and absorbs the energy of the impact
• the 3rd layer of glass fibre ensures the rigidity of the entire helmet to prevent lateral compression
• the 4th layer is the polystyrene shell, which completes the deceleration of the impact by crushing under the impact, thus protecting the cranial box from skull injuries
• thanks to its numerous front and side openings and its rear extractors, this helmet offers maximum ventilation
• the new one-piece and removable liner can be washed and replaced if necessary. The soft and fluffy interior is antibacterial treated
• the Twin Lock System (TLS), the patented rigid chin strap, has been completely redeveloped to offer maximum stability and support, previously reserved exclusively for motorbike helmets
• the thermoplastic resin chin strap offers extended neck protection, as the coverage area is larger than that of conventional helmets
• the reinforcement provided by the chin strap of the shell increases resistance in the event of an accident
