Giro Helios Spherical Road Cycling Helmet

The Giro Helios Spherical Road Cycling Helmet combines cutting-edge safety with superior comfort for road and gravel riding. Its innovative Spherical Technology features a ball-and-socket design powered by Mips® brain protection, allowing the outer liner to rotate during impact to reduce rotational forces. Progressive Layering uses dual-density EPS foam to manage both high and low-speed impacts effectively. Engineered for all-day comfort, the helmet boasts 15 Wind Tunnel vents with internal channeling that forces air directly over your scalp for exceptional cooling. The patented Roc Loc 5 Air fit system suspends the helmet slightly off your head, maximizing airflow while letting you adjust fit and tilt with one hand. Plush Ionic+® antimicrobial padding with natural silver odor protection keeps you fresh through long rides. Built to exceed safety standards while prioritizing ventilation and adjustability, the Helios is your trusted companion for every road and gravel adventure.

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™ — Giro helmets with Progressive Layering™ use two different density EPS foam liners to address high- and low-speed impacts for more comprehensive energy management.

 
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 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.

 
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 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.

 
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.
