GPA - 4S Speed Air Hybrid Riding Helmet black matt

• 4S Speed Air riding helmet
• Designed to provide optimal protection
• Four-layer construction progressively absorbs impacts and improves resistance to lateral compression
• The 4S model has four layers. The first is an outer shell made of an impact-absorbing polymer designed to deform on impact and absorb the initial force. The second layer, 2S, absorbs more of the impact energy. The third layer, 3S, is the main shell, reinforced with fiberglass for rigidity and protection. By this point, the first two layers have already absorbed part of the impact. Finally, the EPS inner liner, 4S, compresses under pressure to slow the impact, helping protect your head and reduce the risk of head injury
• The injection-molded outer shell helps reduce the risk of punctures
• Optimal ventilation through front openings and rear exhaust vents
• The inner liner is made of EPS to absorb and distribute impact forces
• A thicker EPS layer provides greater comfort and impact absorption
• The helmet liner is made of soft, antibacterial fabric. It is removable and washable
• The visor is made of flexible thermocomposite resin
• Hybrid chinstrap combines flexibility and a secure fit with added protection extending over the back of the neck
• Combines the TLS system with a traditional chinstrap
• Flexible fastening with a rigid section protecting the back of the neck for added safety
• Rear section made from thermocomposite resin and injected fiberglass extends the shell for greater coverage
• Chinstrap structure reinforces the helmet against side compression and improves stability, reducing the risk of the helmet tipping
• Two-part buckle is easy to fasten and release
• Interior 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.
