The Octal X helmet has been specifically designed for XC mountain bike riding and developed from the same technology and design as the award-winning Octal road helmet, notably the extreme ventilation, low weight, unibody shell construction and aerodynamic efficiency. To optimize the helmet for the specific demands of XC mountain biking, the Octal X has added robustness and protection. The inclusion of POC’s proven aramid bridge technology adds structural integrity and guards against impact penetration. A fundamental addition to the Octal X’s improved performance and safety is the extended helmet shell, which covers more of the helmet liner ensuring that the helmet has enhanced strength properties with very little increase in weight. The Octal X compliments the existing POC helmet range and mountain bike riders will now have helmets to suit all their riding needs.
