The SIGMA design not only features KPLUS's unique tenth-anniversary mark but also groundbreakingly incorporates air vents and flow channels within the helmet shell. Through countless wind tunnel experiments and precise adjustments, it aims for the ultimate airflow and heat dissipation performance. The streamlined design of the flow channels allows air to pass efficiently while maintaining excellent heat dissipation during movement. The SIGMA helmet achieves a perfect balance while maintaining essential weight and safety.
