The Aerohead MIPS II Road Helmet was designed in the wind tunnel, tested on the track, and has been proven with record-breaking times at the Tour de France and Ironman World Championships.

The Aerohead Mips® is ideal for triathletes and time-trialists who need the optimal balance of advanced aerodynamics and cooling power. It features an aerodynamically efficient profile, constructed with a lightweight polycarbonate shell. The Wind Tunnel™ ventilation and internal channelling keep you cool when the competition heats up.

The Aerohead Mips features a unique wrap-around eye shield with Optics by ZEISS® that offers an unblocked field of view and unrivalled clarity. A magnetic anchor attachment keeps the shield secure, yet it's easy to remove and store in the "flipped up" position, making for quick transitions to the bike.

It is equipped with the Mips system to redirect impact energy, which can provide more protection in certain impacts

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 body's 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 helmet's shell with exhaust channels inside the helmet that thrust fresh, cool air over and around the rider's head while forcing heat and stale air out. It's 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.
• Weighing is at 450g (size Medium) and certified to CPSC, CE standards
