Engineered for riders obsessed with speed, the Eclipse Pro is designed to win, blending our most advanced aerodynamics with category-leading protection and all-day comfort.
From breakaway victories at the Tour de France to record-setting wins at Leadville Trail 100, the Eclipse Pro is advanced engineering for riders obsessed with speed. The result of deep collaboration with the world's fastest pros, endlessly refined with CFD in the Giro lab and then proven in the windtunnel, the Eclipse Pro is 17% faster than the legendary Eclipse. With superior protection from Spherical Technology powered by Mips® and Aura II reinforcement, all-day cooling power and comfort from 15 Wind Tunnel vents and the DryCore sweat management system brow pad, and an ultra light weight that rivals the lightest full-vented road helmets, the Eclipse Pro is designed to win.
- 17% faster than previous Eclipse model.
- Designed using CFD to optimize aerodynamics.
- Validated by wind tunnel testing.
- 15 vents optimized for cooling and aerodynamics.
- Front center vent designed to split air to the forehead and over the brow for aerodynamic efficiency.

Technology
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.
15 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.
Ultra Low Weight
At a mere 280g (medium CPSC) this aero road helmet is lighter than many competitor’s fully-vented ‘climbing’ helmets.
Aura II Reinforcing Arch
The shatter-resistant and translucent Aura II Reinforcing Arch runs throughout the helmet; bolstering structural integrity and allowing massive vents for cooling.
DryCore™
The DryCore™ sweat management system utilizes an internal silicone bead to redirect moisture away from the rider's brow and eliminate the irritation of sweat dripping into the eyes.
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.

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.
