'.strtoupper('t')he goal of giros mips equipped helmets is to reduce rotational forces'. '.strtoupper('w')hat is mips?mips is a brain protection systemrotational motion can cause brain injuriesthe low friction layer allows a sliding movement of 10ndash15 mm, in all directions, reducing rotational motion to the brain during impactmips adds protection roc locreg air fit system this revolutionary fit system adds a new dimension to helmet performance by enhancing cooling, as well as fit comfort and stability'.
