One of the extraordinary features of the Manifest is the Spherical safety system, which eliminates the traditional plastic sliding surface on the inside of the helmet. With the Spherical Design, this sliding surface is seamlessly integrated between the two layers of EPS foam and offers you the benefits of the MIPS® system and the progressive inner shell without restricting comfort or ventilation. The Roc Loc® Trail Air adjustment system has also received a generous upgrade, ensuring a snug fit on rough terrain. It is even UV-resistant, while improving ventilation and allowing you to adjust the fit of your helmet quickly and easily. As you push your limits on the pedals, you'll quickly feel the benefits of the incredibly efficient ventilation system. The Manifest truly sets new standards in terms of style, design and performance.
