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.
