The road cycling Ventral Air SPIN performance helmet is designed to deliver coolness in ways like never before. VENTRAL AIR SPIN HELMET FEATURES: SPIN technology (Shearing Pad INside) - our patent-pending silicone pad technology systemThis low profile road cycling helmet offers specific airflow zones that enhance ventilation, cooling, and aerodynamics360° size and strap adjustment system for the most precise and secure fitFully wrapped unibody shell construction and an EPS liner, delivering an ideal balance between weight and safetyAn eye garage for easy and secure storage of cycling glasses when not in use AIRFLOW ZONES This low profile road cycling helmet provides a supreme cooling effect due to precise ventilation ports and internal channels to control air intake and release at both low and high speeds, while the aerodynamically optimized trailing edge reduces turbulence. Ideal for long rides in the mountains or hotter days in the saddleIt is just one of POC's features that form our whole-helmet to POC design approach that we always take when creating head protection Winner of the coveted Design and Innovation Award 2019, the exceptionally Ventral Air SPIN works to enhance a riders aerodynamic profile and minimize drag BUILT TO RIDE.
