Eclipse Spherical Helmet
Please select a size.
- 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.

Technology

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.

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.

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.

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.

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

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.

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.

Size Chart
Bike Helmet Size Guide
How to measure your size – Wrap a measuring tape around your head, keeping the tape level from front to back. Note the measurement and reference the Size Guide. Note: Make sure the helmet fits with a little room when the fit system is loose, and sits low enough to protect your forehead without hindering your vision. Once you’ve got the right size, you can adjust the fit.

FOR HELMETS EQUIPPED WITH MIPS TECHNOLOGY, PLEASE REVIEW THE FOLLOWING WARNING: SOME MIPS® LOW-FRICTION LAYERS, ALONG WITH OTHER PARTS OF A HELMET, MIGHT CAUSE LACERATIONS TO THE WEARER’S HEAD/FACE IN SOME ACCIDENTS. THIS MIGHT OCCUR DUE TO THE HIGH PRESSURE ON THE SCALP FROM THE IMPACT OR AS A BY-PRODUCT OF THE LOW-FRICTION LAYER’S MOVEMENT IN CERTAIN ANGLED IMPACTS TO HELP REDUCE THE ROTATIONAL ENERGIES TO THE HEAD.
