The Giro Helios™ Spherical Helmet is designed for road and gravel riders seeking advanced protection, exceptional ventilation, and lightweight comfort. Inspired by Giro’s premium performance helmets, it combines compact aerodynamic styling with Spherical Technology™ powered by Mips® to help redirect impact forces. With deep internal channeling, antimicrobial padding, and a highly adjustable fit system, the Helios delivers all-day comfort and confidence whether you’re climbing, racing, or exploring rough backroads.
MIPS® Brain Protection System is a helmet-integrated, low-friction layer designed to reduce rotational motion transferred to the brain from angled impacts to the head.
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 Mips 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 Mips; allowing you to easily custom tune fit tension and fore-aft tilt of the helmet in seconds using a single hand.
Pure Silver is the secret ingredient that gives IONIC+® the power to provide natural; permanent odor protection to keep your helmet feeling fresh.
Wind Tunnel Ventilation 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.
Spherical Technology’s ball-and-socket design, powered by Mips®, helps redirect impact forces by allowing the helmet’s outer liner to rotate independently around the inner liner during certain impacts. The design also eliminates hard plastic slip planes against the rider’s skin for improved comfort.
