"What Our Gearhead® Experts Are Saying:""The POC Procen Air is the helmet I recommend when someone wants genuine aero performance without cooking their head at race pace. The Venturi-inspired ventilation system moves air across the full head in a way most aero helmets simply don't, and the integrated 2-position lens eliminates the sunglasses decision entirely. The magnetic rear storage system makes stashing the lens mid-ride effortless, and the molded EVA neck pad is a comfort detail that pays off on long efforts. Built for riders who race as seriously as they train.""Aerodynamic helmets have traditionally asked riders to choose between speed and comfort. POC's Procen Air declines that trade-off, taking the shape of a classic time-trial helmet and engineering Venturi-inspired ventilation into it for full-head cooling that holds up through long efforts and sustained race pace. The PC shell and EPS liner deliver structural integrity and crash protection without adding weight, and partial ear covers reduce wind noise on high-speed descents without blocking awareness. The integrated 2-position lens keeps eyes covered and fog-free without requiring sunglasses, and a magnetic rear attachment system stores the lens cleanly mid-ride when conditions change. A molded EVA neck pad adds comfort through the miles where the helmet meets skin, making the Procen Air as livable on a long training day as it is fast on race day."
