Eclipse Pro: Designed to win - Learn more
Eclipse Pro
Designed To Win
From the Tour de France, with Wout Van Aert’s breakaway victory on the Champs Elysées and Pauline Ferrand-Prévot’s GC triumph atop the Col de Madeline, to the Leadville MTB 100 and Kate Courtney’s record-setting win, the Eclipse Pro is our most 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 wind tunnel, the Eclipse Pro is 17% faster than the legendary Eclipse. With superior protection from Spherical Technology powered by Mips® combined with all-day cooling power and comfort from 15 Wind Tunnel vents, plus an ultra low 280g weight that rivals the lightest full-vented road helmets, the Eclipse Pro is designed to win.

[ 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.
