Giro Manifest Spherical MTB Helmet - 2024


Why compromise? For the riders that demand the best equipment, meet Giro’s new Manifest Spherical helmet. With Spherical Technology, best-in-class ventilation, full coverage and luxurious comfort, Manifest is the most premium trail riding helmet available.

Among the Manifest’s extraordinary features is Spherical Technology which utilizes a ball-and-socket design 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.

MIPS® Spherical
A reimagined version of the MIPS® Brain Protection System that eliminates the plastic slip plane of the original MIPS design.

Roc Loc® Trail Air
The revolutionary Roc Loc® Air Fit System has the same outstanding features as the Roc Loc® 5, but in addition to that, it dramatically increases airflow and ventilation inside the helmet. This fit system offers dynamic strength and UV-resistance while improving ventilation and comfort.

In-Mold Construction
In-Mold Construction fuses a tough polycarbonate outer shell with the helmet's impact-absorbing foam liner. The fusion process allows for better ventilation systems, making in-mold helmets lighter and cooler than traditional helmets.

Wind Tunnel Ventilation
Giro's helmets are developed utilizing their proprietary Wind Tunnel™ ventilation system. This elaborate design combines active vents in the helmet’s shell with exhaust channels inside the helmet that thrust fresh, cool air over and around the rider’s head while forcing heat and stale air out. It’s the most effective cooling system available, and a difference you can feel every time you ride.
