Three shell sizes to more accurately fit a variety of head sizes and rider ages, improving overall safety

PATENTED BRAIN PROTECTION SYSTEM

MIPS stands for Multi-directional Impact Protection System, a revolutionary technology that allows the helmet to slide relative to the head, adding more protection against the rotational violence to the brain caused by angular impacts.
