GPA 4S Speed Air TLS Helmet

The 4S helmet range is designed with 4 layers whose combination provides remarkable shock absorption, as well as improved resistance to penetration and compression during an impact.

• The outer shell, made of injected polymer, protects against sharp objects (which could pierce the shell) and absorbs the initial shock waves by deforming or breaking.

• The second layer of high-density EVA foam absorbs part of the shock waves, reducing the energy transmitted to layers 3 and 4.

• The third layer is a shell made of injected polymer reinforced with fiberglass. It strengthens the helmet by absorbing part of the impact energy and offers a second protection against blunt objects.

• The fourth layer is the expanded polystyrene (EPS) liner. It absorbs the remaining shock waves, thereby protecting the skull from head injuries.

NEW EPS (shock-absorbing liner): better fit

With safety at the heart of GPA's concerns, the entire 2022 collection benefits from a completely redesigned EPS. Its thickness has been increased to ensure better cushioning and reduce the transmission of shock waves. It also ensures the rider's comfort thanks to the new shape of the interior and optimal ventilation.

NEW LINER: unmatched comfort

Since you wear it for several hours a day or week, our new interior has been completely redesigned for increased comfort.

Made in one piece, it is removable, making it easy to wash or replace. This new liner slides between the EPS and the outer shell using semi-rigid tabs. No more Velcro or clips that could bother the rider; this new liner is fixed using semi-rigid tabs between the shell and the shock-absorbing element (EPS).

The fabric is treated to be antibacterial and sweat-resistant. It is washable by hand or machine at 30 degrees with a neutral soap.

The TWIN LOCK SYSTEM chinstrap: a true revolution

THE HIGHEST LEVEL OF SAFETY DUAL CERTIFICATION European Certification EN 1384 2017 Certification VG1

Chosen by the world's top riders such as Christian Ahlmann, Pénélope Leprevost, Julien Epaillard, and Denis Lynch, the rigid CONCEPT chinstrap returns even more efficient in 2022! After 5 years of study, this chinstrap system has been completely redesigned to bring multiple improvements.

WHY CHOOSE THE TWIN LOCK SYSTEM?

TLS: UNPARALLELED SAFETY

A hold and stability previously reserved exclusively for motorcycle helmets. An extended coverage area to the neck and temples for greater protection. A design that strengthens the helmet in the event of compression. A sense of security and freedom: a wider field of vision thanks to the absence of straps obstructing the face. The new FidLock magnetic closure opens and closes quickly with one hand. The TLS system reduces the risk of poorly adjusted chinstraps (dangerous and unaesthetic). TLS: OPTIMAL COMFORT

Flexible branches that make it easier to put the helmet on. Removable foam pads have been added to the branches of the TLS for a soft touch against the rider's skin. The dimensions of the Twin Lock System are adapted to the size of the helmet to ensure an optimal fit!
