The Giro Eclipse Spherical Helmet has been created to offer refined aerodynamic performance matched with agressively cool airflow and the best in head-protecting technology. For road and gravel racing and training it's the ultimate pick.
Thanks to its smooth, streamlined design, the Eclipse Spherical Helmet delivers low-drag performance for fast riding. But of course it's not just about speed, it also gives you a mix of technology to keep you safer in the event of a crash.  
This mix of technologies includes Spherical Technology™, power by MIPS® brain protection systems, and Giro's own Progressive Layering™ construction. At it's heart the in-mould design features a shock-dissipating EPS foam liner, protecting your head in an impact. And here the Progressive Layering™ also focuses on providing separate inner and outer layers to manage high and low-speed impacts.
To the outside, the polycarbonate shell offers a durable and tough layer to resist knocks and bumps and this coverage extends fully to the bottom for maximum coverage. 
Spherical Technology powered by MIPS® (Multi-Directional Impact Protection System) 
As you'd expect, all Giro helmets are designed to not only meet but also exceed stringent safety standards. The ball and socket Spherical Technology, powered by MIPS, allows the outer liner to rotate around the inner liner during a crash, ensuring you enjoy an extra level of brain-protecting technology, designed to redirect energy and provide more protection in certain impacts.
This system also eliminates contact of plastic and slip planes with your skin, boosting your overall riding comfort.
Airflow Optimised
When you're pushing out the watts, you'll soon be feeling the heat and building a sweat. But here the 14 Wind Tunnel™ vents deliver the airflow you need to stay cooler when a more intense pace starts to bite. Once the air is inside it's channelled over your head to boost comfort while sweaty air is expelled out the back. 
This cool airflow is complemented by the Ionic+™ anti-microbial padding. With its resistance to bacteria, this padding keeps you feeling fresh and prevents that itchy feeling that comes with less premium padding. 
Roc Loc® Air 5 System
Setting the standard for ease of adjustment, stability and comfort, the Roc Loc® Air 5 System ensures you always get the right fit of your helmet. It allows for precise adjustment, with both fore-aft tilt and single-hand dial adjustment. 
It also allows for uncompromised airflow to your head. The design allows a smooth passage of cooling air through the vents and along the inner air channels.  And it’s lighter than comparable systems too, making it the ultimate in skull-hugging luxury.
