Powered by M12™ REDLITHIUM™ Battery Technology, these heated vest kits use carbon fiber heating elements to create and distribute heat to the chest and back. A single touch LED controller heats up the battery heated vest to three heat settings. New Quick-Heat function creates and distributes heat three times faster than previous vests and market competitors. These vests are built with AXIS™ Ripstop Polyester providing a lightweight, compressible design that can be used as an outer shell or a mid-layer vest, and protecting from wind and water. Includes: M12™ Heated AXIS™ Vest (303-20), M12™ REDLITHIUM™ CP1.5 Battery Pack, M12™ battery holder.
