The Manifest Spherical Helmet premieres Giro's revolutionary Spherical Technology for enhanced safety on the trail. Powered by MIPS, Spherical Technology utilizes a similar slip-plane design as MIPS for greater impact absorption at angular crashes, except Spherical opts for two layers of foam with a slip-plane between the two, instead of a plastic liner. This redirects impact energy by rotating the exterior liner independently from the interior liner, and it enables greater ventilation for a cooler time on the trail as well as a safer one. Giro geared the Manifest for sweaty riding in hot weather with nineteen Wind Tunnel vents, all amplified thanks to Aura's reinforcement around the arch. XT2 padding provides a comfortable fit, and the lining wicks sweat, dries quickly, and reduces any unwanted odors. Giro also redesigned the Roc Loc Trail Air Fit System for enhanced durability and dynamic strength. The visor adjusts to accommodate eyewear and goggles, and Giro included grippers to make sure either stay in place.
