The Eclipse Spherical is an outstanding aero road helmet that combines the best technologies of Giro in a lightweight, compact form, ideal for use on the road bike or gravel bike. The slim outer shell actively directs airflow to maximize drag reduction at different wind angles. In addition, 14 Wind Tunnel vents provide incredible cooling performance.Inside, MIPS Spherical technology provides enhanced safety. The outer EPS helmet shell rotates a few millimeters around the inner helmet shell in the event of an impact to minimize the rotational forces generated by the impact. The progressive inner and outer shells with different EPS foam densities also contribute to comprehensive protection. The patented Roc Loc 5 Air system improves comfort and fit. The soft Ionic+ padding provides exceptional sweat absorption and has an antimicrobial effect.MIPS SphericalMIPS Spherical is the evolution of the Multi-Directional Impact Protection system. Manufactured in Giro's signature design, the two layers of EPP foam in two degrees of hardness act as a kind of joint that can move a few millimeters in each direction, effectively reducing rotational energy at certain impact angles.
