The fully wrapped unibody shell construction featured on the POC Octal Raceday Helmet functions as a monocoque unit and enhances the safety properties and construction integrity of the helmet while maintaining a low weight. POC has approached ventilation in a unique way that uses larger ventilation slots rather than multiple small vents. This ventilation design allows more air to flow through the helmet, which also results in improved aerodynamic performance. The lightweight size adjustment system ensures a comfortable and secure fit while the Coolbest padding helps reduce the temperature at the interface between the helmet and head. The helmet is offered in different color options as well as three size options. With matching POC Do Blade or DO Half Blade sunglasses you are sure to turn heads on your next ride!
