MIPS SPHERICAL - ESSENTIALLY AN INVISIBLE LOW-FRICTION LAYER SANDWICHED WITHIN TWO LAYERS OF EPS FOAM, THE RESULT IS A REDUCTION OF ROTATIONAL FORCES AND THE ELIMINATION OF THE PLASTIC SLIP PLANE OF THE ORIGINAL MIPS DESIGN. REDIRECTS IMPACT ENERGY BY ALLOWING THE HELMET'S EXTERIOR LINER TO ROTATE INDEPENDENTLY OF THE INTERIOR LINER IN AN ANGLED IMPACT.
