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.

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.
