Once saturated with water the Challenger vest's natural cooling properties are activated simply by opening your jacket's ventilation features and exposing the charged vest to passing airflow. Once activated, the Challenger cooling vest helps riders maintain a comfortable body temperature and, ultimately, stay in control. The Challenger can be zipped directly into select REV'IT! jackets for a clean, integrated fit effectively amplifying a jacket's existing airflow for up to six hours.
Note: Vest does not connect to all REV'IT! jackets.
