The MET Trenta MIPS a performance road helmet engineered to maximize ventilation and save you energy with every pedal stroke. Featuring the MIPS-C2 rotational management system, the MET Trenta MIPS is able to slide in the case of a crash, redirecting damaging rotational motion. MIPS is a brain protection systemengineered to add protection to the standard construction of helmets in case of certain impacts. Scientifically designed air vents harness the power of the Venturi effect, pushing out warm air within the helmet through specially positioned exhausts to ensure constant airflow. The tail of the helmet also features an aerodynamic design to effectively drive airflow.
