Giro Aherohead Ii Mips Time Trial Helmet S

Details

• 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 while enhancing fit and comfort by combining the Mips slip plane with the helmet's adjustable fit system.
• 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.
