Protection that keeps up

Kids get more daring as they grow older, so they need a helmet to match. Big Dipper Kids' features Multi-directional Impact Protection System (MIPS) technology—developed by brain surgeons and scientists to reduce rotational forces on the brain caused by angled impacts to the head—for extra protection on every new stunt attempt.

MIPS (Multi-directional Impact Protection System) was developed by brain surgeons and scientists to help reduce rotational forces on the brain caused by angled impacts to the head.
