The streamlined profile is achieved through the new Passive Aggressive Venting system, a discreet yet powerful system that automatically manages airflow and temperature while in-motion riding, hiking or standing static. The overall look is finished with a slight brim and subtle lines for Seamless Compatibility with Giro goggles. The Terra Mips® Helmet also features Mips® technology, lightweight construction and the dialed-in fit of the In Form 2 Fit system for a barely there feel.
