GPA 4S Speed Air TLS

Pushing Boundaries
Like all GPA helmets, the 4S has been developed for maximum protection. The 4S helmet represents a technological revolution, as its four layers provide remarkable shock absorption and improved resistance to lateral compression.

Unmatched Shock Absorption
The outer shell, made of shock-absorbing polymer, absorbs the initial impact through deformation. The second layer dampens and absorbs the energy of the impact. The third layer, made of fiberglass, provides the overall rigidity of the helmet and prevents lateral compression. The fourth layer is the polystyrene shell, which slows down the impact of shocks and protects the skull from injuries.

Optimal Ventilation
Thanks to its numerous front and side openings, as well as rear exhaust vents, this helmet offers maximum ventilation.

Unparalleled Comfort
The new, removable one-piece inner lining can be washed and replaced if necessary. It is soft and padded and treated to prevent the growth of bacteria.

Optimal Safety Through Unmatched Stability
The patented Twin Lock System (TLS) with a rigid chin strap has been completely redesigned to provide optimal stability and support that was previously reserved for motorcycle helmets. The thermoplastic resin chin strap offers additional neck protection due to a larger coverage area than conventional helmets. The chin strap reinforces the helmet shell and increases its resistance to lateral impacts. The new Fidlock magnetic closure opens and closes quickly with just one hand, significantly easing handling. The flexibility of the TLS system provides more comfort by adapting to individual body shapes. The TLS chin strap is a registered trademark of the new GPA riding helmet collection.

Foam is always included with the purchase of a GPA helmet.
