Aerohead II Mips® is our most aerodynamic time trial helmet ever, designed with CFD and VR, and proven in the wind tunnel with the world's fastest riders on Team Visma.Making the fastest riders faster is our mantra and the Aerohead II Mips is the first product of our partnership with the world's fastest riders on Team Visma / Lease a Bike. Designed with CFD and VR, proven in the wind tunnel with 2x Tour de France winner Jonas Vingegaard, the Aerohead II Mips® is our most aerodynamic time trial helmet ever. With the protection of Mips® Air Node, a lightweight and ventilated solution for rotational energy management CE and CPSC safety standards are met and exceeded. Visibility is optimized with a magnetically attached oversized eye shield by Zeiss® Optics that is positioned away from the rider's face, allowing air to flow over the brow and beneath the Roc Loc® 5 Air fit system. Each Aerohead II comes with two eye shields (Clear and Vivid® Smoke) and a padded carrying pod. Engineered speed — the Aerohead II is your advantage.

Key Features The two‐piece shell combines a tough outer hard shell with a polycarbonate lower shell permanently fused to the liner for durability without excess weight. The Mips® Air Node system is a low‐friction layer laminated onto the base of the comfort padding, and is a lightweight and highly ventilated solution to reduce rotational energy. It is connected to the energy‐absorbing liner with nodes of hook‐and‐loop fabric touch fasteners. At angled impacts, the nodes are designed to release locally, allowing the padding to slide and reduce rotational motion to the head. In addition to helping to optimize stability and cooling airflow through the helmet, the micro‐adjustable ergonomic and compact dial allows riders to adjust vertical positioning and tune the contact points independently for a customized fit with exceptional comfort. Our proprietary Super Fit sizing system is based on human scale factors data and over 25 years of handcrafting helmets. By creating helmet molds in up to 4 adult sizes to match the human bodys form, our Super Fit sizes comfortably and securely fit riders, and feel like they are custom made just for you. Giro helmets are developed utilizing our proprietary Wind Tunnel™ventilation system. This elaborate design combines active vents in the helmets shell with exhaust channels inside the helmet that thrust fresh, cool air over and around the riders head while forcing heat and stale air out. Its the most effective cooling system available, and a difference you can feel every time you ride. Pure Silver is the secret ingredient that gives IONIC+® the power to provide natural, permanent odor protection to keep your helmet feeling fresh. The inner liner of the helmet is aggressively engineered to assist air flowing through the helmet, working in conjunction with our Wind Tunnel vents to provide an easy pathway for cool air to flow in and hot air to exhaust out. Technology Integrated MIPS® Brain Protection System All Giro helmets are designed to reduce as much energy as possible while meeting and exceeding stringent safety standards. The goal of Giros Mips-equipped helmets is to reduce rotational forces. Giro believes that helmets equipped with this technology can reduce the amount of rotational force that may be transferred to riders brain in certain impacts. Roc Loc® 5 Air MIPS Fit System This revolutionary fit system adds a new dimension to helmet performance by enhancing cooling, as well as fit comfort and stability. Using a patented design that suspends the helmet just slightly off the top of the skull, Roc Loc 5 Air Mips allows cool airflow to pass directly over your head, further enhancing the performance of vents and internal channeling that exhaust heat out of the helmet. Fit and feel adjustments mimic the Roc Loc 5 Mips, allowing you to easily custom tune fit tension and fore-aft tilt of the helmet in seconds using a single hand.
