The Aerohead™ Mips® 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 channeling 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 unrivaled 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.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.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 Giro´s Integrated 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 rider´s brain in certain impacts.ROC LOC® 5 Air Fit System:- 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.Super Fit™ Engineering:- 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.Wind Tunnel Ventilation:- 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.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.Specifications:- Weight: 450g - Material Composition: 55% EPS, 29% PC, 2% POM, 3% Polyester, 9% Nylon, 2% PU
