GPA Helmet 4S Speed Air Hybride Black Mat

The GPA 4S Speed Air Hybrid riding helmet combines comfort and safety. Created with protection as a priority, GPA 4S is a technological revolution with its 4 layers that allow optimal shock absorption and better resistance to lateral compression.

GPA Hybrid chin strap
Thanks to the extended rigid part at the back that forms the shell, the Hybrid chin strap guarantees more comprehensive protection and better support of the riding helmet on the head. The rear part, which extends over the Twin Lock system and the traditional chin strap, is made of thermocomposite resin and injected fiberglass. The nylon mounting straps, covered with artificial leather, close with a two-piece buckle.

GPA 4S Unparalleled cushioning
1S - The outer shell, made of injected polymer, protects against elements that could perforate the cap and dampens an initial part of the shock waves.
2S - The second layer of high-intensity EVA foam absorbs and reabsorbs some of the shock waves, reducing the energy transferred to layers 3 and 4.
3S - The third layer is an injected polymer shell reinforced with fiberglass. This cap, which is stiffer than that of the 1st layer, strengthens the helmet in case of crushing, absorbs some of the energy and provides extra protection against the harsh elements.
4S - The 4th layer is the expanded polystyrene (EPS) liner that completes absorption and transmits shock waves by crashing upon impact. It thus protects the cranial vault against head lesions.

An optimal ventilation system
Thanks to the numerous openings on the front and side and the extractors on the back, this helmet offers maximum ventilation.

Unparalleled comfort
The new lining is made in one piece and is removable, making it easy to wash or replace. It slips between the shell and liner using semi-rigid plastic tabs. The soft and fluffy fabric is antibacterially treated.
