POC Ventral Air MIPS Helmet Maximum cooling, minimum drag When the heat is on and the climbs are long, the POC Ventral Air MIPS is the helmet built for the job. Developed under POC's Whole Helmet Concept(TM) - where every design decision is considered together from a rider's perspective - the Ventral Air MIPS pairs aggressive ventilation with genuine aerodynamic performance. Precisely placed ventilation ports feed deep internal airflow channels that control air intake and release at both low and high speeds, while a distinct 22deg trailing edge minimizes turbulence for a more aerodynamic silhouette. Lightweight, well-protected, and dialed in - this is the go-to helmet for hot days and hard efforts. Features Precisely placed ventilation ports with deep internal airflow channels provide optimum control of air intake and release at both low and high speeds for supreme cooling across the whole head22deg aero trailing edge controls residual airflow around the helmet to minimize turbulence and reduce drag without sacrificing ventilation CFD-tested aero design optimizes the helmet's aerodynamic profile to minimize drag in real-world riding conditions Mips Air Node system - a low-friction layer laminated to the base of the comfort padding - works to redirect rotational impact forces during certain crashes Optimized EPS liner provides crash protection without adding unnecessary weight Fully wrapped unibody PC shell improves structural stability and enhances overall helmet integrity Lightweight 360deg fit adjustment system provides a secure, personalized fit Integrated eyewear garage for secure, easy storage of sunglasses mid-ride SPECIFICATIONSMIPSMips Air Node Shell Construction Unibody PC Shell Fit System Lightweight 360deg Adjustment Intended Use Road, Road Race Sizing Size Small Medium Large Head Circumference (in)19. 5 - 22"21. 5 - 23"22 - 24"Head Circumference (cm)49. 5 - 55. 9cm54. 6 - 58. 4cm55. 9 - 61cm | Poc | Ventral Air Mips (Cpsc) Helmet Men's | Size Medium In White
