Among the Manifest’s extraordinary features is Spherical Technology which utilizes a ball-and-socket design that’s powered by MIPS® to redirect impact forces. Developed in Giro’s test lab in partnership with MIPS®, Spherical Technology allows the outer liner to rotate around the inner liner during a crash, and eliminates contact with a hard plastic slip-plane against skin. Another major benefit of Spherical Technology is progressive layering—dual-density foam liners designed to address high- and low-speed impacts for more comprehensive energy management.
As you push your limits on the pedals, you’ll appreciate this helmet’s wide-open airflow. The AURA reinforcing arch bolsters structural integrity while allowing air to flow freely into a series of massive Wind Tunnel™ vents and internal channeling. Comfort and sweat absorption are enhanced by quick-drying antimicrobial XT2 padding. You’ll notice this cooling power when you’re hammering in the heat and it’s backed up by our test results (Manifest runs significantly cooler than other trail helmets and rivals our class-leading Aether™ road helmet). Fit and positioning adjustments are achieved with a redesigned Roc Loc® Trail Air fit system that offers dynamic strength and UV-resistance while improving ventilation and comfort. And it almost goes without saying—the Manifest’s sophisticated style and compact design raise the bar for performance and style.
