Among the Manifest's extraordinary features is Spherical Technology, a ball-and-socket design powered by MIPS® brain protection system. Spherical Technology allows the outer liner to rotate around the inner liner during a crash, eliminating contact with a hard-plastic slip-plane and working to further reduce rotational forces. In addition to industry-leading head protection, the Manifest offers wide-open airflow. This is thanks to the AURA reinforcing arch, which bolsters structural integrity while allowing maximum airflow through the massive vents. Combine a comfortable, secure fit with plush, antimicrobial XT2 padding for exceptional sweat absorption and you have the perfect all-day, all-trail, mountain biking helmet.
