MIPS Protection – helmet safety – brain protection system

MIPS is a brain protection system — engineered to add protection to ,helmets,. The MIPS Brain Protection System (BPS) is found inside the ,helmet,, generally between the comfort padding and the EPS (a high-quality foam used to reduce energy). For certain impacts, the MIPS BPS can reduce harmful forces transmitted to the brain.
