Like every GPA, the 4S was created around protection as a priority. The 4S is a technological revolution with its 4 layers which allow optimal shock absorption as well as better resistance to lateral compression. The 4S speed air TLS helmet combines comfort and safety.
An optimal ventilation system
Thanks to its numerous front and side openings and its rear extractors, this helmet offers maximum ventilation.
Unparalleled comfort
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.
Flawless security thanks to unprecedented stability and support
The Twin Lock System, the patented rigid chinstrap, has been completely redesigned to provide stability and support previously exclusively reserved for motorcycle helmets. In thermo-composite resin, it offers extended protection of the neck and rocks because the coverage areas are greater. The reinforcement that the chinstrap provides to the shell offers increased resistance in the event of a lateral crush.
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.
