GPA - 4S Speed Air Hybrid Riding Helmet black matt

• 4S Speed Air riding helmet
• Provides optimal safety
• Designed with 4 layers for successive impact absorption and enhanced resistance to lateral compression
• The 4S model works as follows: the first layer is the outer shell, which absorbs the initial part of any impact — made from an energy-absorbing polymer designed to deform on impact. The second layer, the 2S, captures and dissipates the impact energy. The third layer, the 3S, is the main shell — reinforced with fiberglass to provide rigidity and protection. At this point, the impact has already been absorbed by the two outer layers. Finally, the fourth layer, the 4S, is the EPS inner cap, which decelerates the shock by crushing under the force of impact, protecting the skull and minimizing head injuries
• The outer shell is injection-moulded to reduce the risk of perforation
• Optimal ventilation through front openings and rear extractors
• The inner shell is made from EPS to absorb and distribute shockwaves
• Increased EPS thickness for greater comfort and improved shock absorption
• The helmet liner is made from soft, antibacterial fabric. It is removable and washable
• The visor is made from thermo-composite resin for excellent flexibility
• Hybrid harness system combining a soft chinstrap with enhanced retention and added protection thanks to its extended neckguard
• A blend of the TLS system and a traditional chinstrap
• Flexible fastening with greater security thanks to the rigidity of the neckguard section
• Rear section in thermo-composite resin and injected fiberglass, extending the shell and increasing the coverage area
• Chinstrap frame that reinforces the helmet against lateral crushing, improving stability and reducing the risk of the helmet shifting
• Two-part buckle — easy to fasten and remove
• Inner foam padding included with the helmet

For over 50 years, GPA has been committed to offering riders of all levels the best possible protection and exceptional comfort. GPA helmets are crafted from premium materials — including carbon fibre and high-density foams — to deliver maximum impact resistance while remaining lightweight and comfortable to wear. Each helmet provides a perfect fit thanks to advanced adjustment systems such as Speed Air technology. GPA helmets also feature innovative ventilation systems that promote optimal airflow and prevent overheating during intense effort.
