GPA 4S Speed Air TLS – AVAILABLE SOON

549,00 €

The 4S is a technological revolution with its 4 layers.
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.
Thanks to its front openings and rear extractors, this helmet offers optimal 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.
The Twin Lock System, the patented rigid chinstrap.
For ease of use, the new Fidlock magnetic closure opens and closes quickly with one hand. The better flexibility of the branches offers additional comfort by adapting to the morphology of each one. The TLS chinstrap is the GPA signature of this new collection.
