"Why compromise? If there’s one thing to have the best of, it should be your mountain bike helmet. Meet Giro’s new Manifest MIPS, the most premium trail riding helmet available, with MIPS® Spherical design, best-in-class ventilation, and luxurious comfort."
"Among the Manifest’s extraordinary features is MIPS Spherical design which eliminates the traditional plastic slip plane from the interior surface of the helmet. With MIPS Spherical, the slip plane is seamlessly integrated between two layers of EPS foam, giving you the benefit of MIPS and progressive layering without obstruction to comfort or cooling power. The Roc Loc Trail Air System has also received a generous upgrade, offering high-impact resistance, dynamic strength, and even UV-resistance while enhancing ventilation and allowing you to easily adjust fit and positioning. As you push your limits on the pedals, the incredible ventilation (besting all other trail helmets we’ve tested and rivaling our class-leading Aether™ road helmet) makes a big difference when you’re deep into a full day’s ride. And it almost goes without saying—the Manifest’s sophisticated style and compact design raise the bar for performance and style."
