Giro Tyrant MIPS Bike Helmet

   Polycarbonate Shell with EPS / EPP Liner

   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.

   Progressive Layering™–        Two different materials are used to manage impact energy: One layer is EPS, which is well suited to high-speed crashes. The other is a lower density EPP foam with rebound characteristics that address the more common, low speed impacts.

   Roc Loc® Air DH–        Adjustable fit system enhances the helmet’s comfort, stability, and interior ventilation while reducing the chances of accidental adjustment.

   Super Fit™–        A great helmet is so comfortable that once it’s on, it virtually disappears. Giro’s proprietary three-size Super Fit system is based on “human scale factors” data and over 20 years of crafting helmets for the best bike riders in the world. The result is pure Skull Hugging Luxury™, a helmet that fits 98% of the world’s population, yet looks (and fits) like it was custom made just for you.

   14 Vents

   Stack™ Ventilation–        Vents at the brow line help warm air to be drawn up and away from your goggles to eliminate fogging, while allowing seamless integration with goggles.

   Cheek Pad Ventilation–        Allows cool, fresh air to circulate inside the helmet to help cool you and address sweat management.

   Visor–        Easily adjustable without the need for tools or extra fiddling, offering plenty of vertical adjustment to stage goggles when you’re not wearing them.

   MIPS® Spherical–        MIPS® Spherical is a pair of foam layers that work like a ball and socket to redirect impact energy in a crash. The system uses two distinct layers of foam within the helmet, rather than a single layer of foam and plastic liner. One layer is EPS, which is well suited to high-speed crashes. The other is a lower density EPP foam with rebound characteristics that offer protection in low speed impacts.

   Complies with the US CPSC Safety Standard for Bicycle Helmet for Persons Age 5 and Older
