"Making the fastest riders faster" is Giro's mantra and the Aerohead II Mips is the first product of their 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 Giro's 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 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.

Features:

• HARDSHELL WITH IN-MOLD HARDBODY™ LOWER WRAP
  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.
• MIPS® Air Node
  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.
• ROC LOC® 5 AIR 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 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, allowing you to easily custom tune fit tension and fore-aft tilt of the helmet in seconds using a single hand.
• SUPER FIT™ ENGINEERING
  Giro's 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, their Super Fit sizes comfortably and securely fit riders, and feel like they are custom made just for you.
• WIND TUNNEL VENTILATION
  Giro helmets are developed utilizing their 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.
• IONIC+ ® Padding
  Pure silver is the secret ingredient that gives IONIC+ ® the power to provide natural, permanent odor protection to keep your helmet feeling fresh.
• DEEP INTERNAL CHANNELING
  The inner liner of the helmet is aggressively engineered to assist air flowing through the helmet, working in conjunction with Giro's Wind Tunnel vents to provide an easy pathway for cool air to flow in and hot air to exhaust out.
