The Eclipse Spherical Helmet is Giro's lightest and most sophisticated aerodynamic helmet to date that doesn't skimp on comfort or protection. Building on the extreme foundations laid out by the Vanquish, the Eclipse is Giro's fastest helmet to date offering, yet still offers incredible cooling efficicency thanks to 14 wind tunnel inspired vents and internal channelling that forces air through the helmet. While the all-new Spherical protection system powered by MIPS allows multi-layered impact protection and the Eclipses liner to rotate around the shell. When combined with full Lower Hardbody Coverage for the brain and top of your spine, riders are offered the most comprehensive head protection available currently available. Of course, without Giro's class-leading, plush Roc Loc 5 Air fit system, the Spherical Helmet wouldn't be able to offer such a secure, yet comfortable fit to ensure rider comfort regardless of the weather, event or terrain! The Giro Eclipse Spherical Helmet takes performance to extreme levels saving riders precious Watts, and in the case of an accident, their lives. This is peak performance and comfort.
