Providing premium comfort and ventilation, the Giro Manifest Spherical is a best-in-class trail-riding helmet. Using Spherical technology alongside MIPS, the outer liner rotates around the inner liner during a crash and avoids contact with a hard plastic slip-plane. Keeping you cool are 19 Wind Tunnel vents, which thanks to the AURA reinforcing arch, bolsters helmet strength and promotes air flow. The Roc Loc Trail Air Fit System offers an adjustable fit and the antimicrobial XT2 padding keeps the helmet fresh and you comfortable.
