    MIPS Technology

    MIPS Technology

    MIPS: Multi-Directional Impact Protection System

    The MIPS Brain Protection System is a helmet integrated, low friction layer designed to reduce rotational motion transferred to the brain from angled impacts to the head.

    Injury statistics show that when you fall and hit your head, it’s most common to fall at an angle, compared to a linear fall. Falling at an angle creates rotational motion and science has shown that our brains are very sensitive to rotational forces. MIPS allows the head to move inside the helmet which can reduce the harmful rotational motion otherwise transferred to the brain.

    Fitting dimensions for the Oakley ARO5 MIPS are as follows:

    52cm - 56cm
    54cm - 58cm
