Among the Manifest's extraordinary features is Spherical Technology, which utilizes a ball-and-socket design powered by MIPS, the market-leading brain protection system that helps to reduce rotational forces. Spherical Technology allows the outer liner to rotate around the inner liner during a crash and also eliminates contact with a hard-plastic slip-plane. In addition to leading head protection, the Manifest offers wide-open airflow thanks to the AURA reinforcing arch, which bolsters structural integrity while allowing air to flow into the massive Wind Tunnel vents. You'll also get a comfortable, secure fit with the easy fit and positioning adjustments built in to the Roc Loc Trail Air fit system and plush, antimicrobial XT2 padding for exceptional sweat absorption. - Spherical Technology's Ball-and-Socket design, powered by MIPS, helps redirect impact forces away from the brain by allowing the outer liner to rotate around the inner liner during a crash.

The Switchblade MIPS is an ASTM downhill certified full-face helmet with a removable chinbar so you can easily switch to rowdy when it's time to descend.

The chinbar is easy to remove - just push the buttons under the chinbar, rotate up, and take off—and it's just as easy to reinstall. Another boast-worthy feature on the Switchblade MIPS is the Roc Loc Air DH fit system, which has a bumper around the dial to prevent accidental adjustments if your helmet contacts your backpack or neck brace—all while keeping you cool.
