the outer shell, made of injected polymer, protects against contemptuous elements (which Could perforate the cap) and dampens a first part of the shock waves by deforming or breaking.
the 2nd layer of high intensity EVA foam will absorb and resorb some of the waves of shock, reducing the energy that will be transmitted to layers 3 and 4.
The 3rd layer is an injected polymer shell reinforced with fiberglass. This cap, more rigid than that of the 1st layer, reinforces the helmet in the event of crushing while absorbing a part of the energy and adds extra protection against the harsh elements.
The 4th layer is the expanded polystyrene (EPS) liner which completes the absorption and transmit shock waves by crashing under impact. It thus protects the cranial box from cephalic lesions.
An optimal ventilation system
Thanks to its numerous front and side openings and its rear extractors, this helmet offers maximum ventilation.
This new liner is made of one piece and is removable which makes it easy to wash or renew it. It slips between the shell and the liner using semi-rigid plastic tabs. Its soft and fluffy fabric is antibacterial treated.
Better neck protection and reinforced support
The classic chinstrap is replaced by a hybrid system, a new exclusive from GPA. Straddling the Twin Lock System and the traditional chinstrap, its rear part is made of thermo-composite resin and injected fiberglass. Its nylon attachment straps, covered with imitation leather, close with a two-part buckle (male and female).
Thanks to its rigid part at the back which extends the shell, the Hybrid chinstrap guarantees more extensive protection and better support for the helmet on the head. Its more affordable price and design will win over more conventional riders.
