Giro Helios Spherical Unisex Road Bike Helmet
ADVANCED PERFORMANCE FOR THE ADVENTUROUS
The heart of the Helios's extraordinary design and performance is Spherical Technology, which utilizes a ball-and-socket design powered by MIPS®, the market-leading brain protection system that can help to reduce rotational forces. Spherical Technology allows the helmet's outer liner to rotate around the inner liner during a crash, and also allows Progressive Layering of the inner and outer liners to provide more comprehensive protection and performance. In addition to advanced head protection, the Helios's 15 Wind Tunnel vents provide exceptional cooling power that's enhanced by our patented Roc Loc 5 Air fit system and plush, antimicrobial XT2 padding for exceptional sweat absorption. It's the ideal match for your road and gravel adventures.
SPHERICAL TECHNOLOGY. Spherical Technology’s Ball-and-Socket design, powered by MIPS, helps redirect impact forces away from the brain by allowing the outer liner to rotate around the inner liner during a crash, it also eliminates contact with hard plastic or slip-planes against the skin.
PROGRESSIVE LAYERING. Helmets with Progressive Layering feature a dual-density liner designed to address high and low-speed impacts, for more comprehensive energy management.
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. 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.
WIND TUNNEL INTERNAL CHANNELING. Combined with the massive vents, internal channeling forces air to flow over the scalp, providing remarkable cooling power.
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 air flow 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.
IONIC+ PADDING. Pure silver is the secret ingredient that gives IONIC+ the power to provide natural, permanent odor protection to help keep your helmet, feeling fresh.
