Giro Eclipse Spherical Helmet

The aerodynamic Eclipse Spherical is our most sophisticated, stylish, and lightweight aero road helmet, and it's crafted with Spherical Technology powered by Mips®, so you can ride with more comfort and an additional layer of protection.

Features

The Eclipse Spherical is both the fastest road helmet and the coolest aero road helmet Giro has ever created, bringing our best technologies together in a light, compact form that's ideal for road and gravel racing. The sleek outer shell actively streamlines airflow to reduce drag across multiple wind angles, while 14 Wind Tunnel vents pull air through the helmet to provide incredible cooling power that rivals our most aggressively vented road helmets. Inside, the ball-and-socket design of Spherical Technology is powered by the Mips® brain protection system, which allows the helmet's outer EPS foam liner to rotate around the inner foam liner during a crash to help redirect impact forces away from the brain. Progressive Layering of both the inner and outer liners help to offer more comprehensive protection, too. The patented Roc Loc® 5 Air system enhances stability and fit, and plush antimicrobial Ionic+ padding helps absorb sweat and moisture while providing durable antimicrobial performance.

Transform Air

Transform Air Technology actively streamlines airflow to reduce drag across multiple wind angles. It optimizes aerodynamics by making the helmet appear longer to the wind, while still retaining an aero advantage in a head-down sprinting position.

14 Wind Tunnel Vents

Giro helmets are engineered with our proprietary Wind Tunnel venting system. This elaborate design combines active vents in the helmet's shell with exhaust channels inside the helmet that thrust cool, fresh air over and around the rider's head while forcing heat and stale air out.

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 designed with Progressive Layering™ use dual-density EPS foam liners to address high- and low-speed impacts for more comprehensive energy management.

Deep Internal Channeling

The inner liner of the helmet is aggressively engineered to assist air flowing through the helmet, working in conjunction with our Wind Tunnel vents to provide an easy pathway for cool air to flow in and hot air to exhaust out.

Roc Loc® 5.5 Air Fit System

Using a patented design that suspends the helmet just slightly off the top of the skull, Roc Loc® 5.5 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 adjustments mimic the Roc Loc 5, allowing you to easily custom fine-tune fit tension and fore-aft tilt in seconds using just one hand. Reflective decals provide added visibility.

Ionic+® Padding

Pure silver is the ingredient that gives IONIC+® padding the power to provide permanent, natural odor protection to keep your helmet feeling fresh.
