The MILWAUKEE(R) M12(TM) Women's Heated AXIS(TM) Vests are designed to protect from the cold and weather on the jobsite. Powered by M12(TM) REDLITHIUM(TM) Battery Technology, these heated vest kits use carbon fiber heating elements to create and distribute heat to the chest, back and shoulders. A single touch LED controller heats up the battery heated vest to three heat settings. This MILWAUKEE(R) heated vest has a new Quick-Heat funtion that creates and districutes heat three times faster than previous vests and market competitors. These women's vests are built with AXIS(TM) 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. | Milwaukee Tool M12 Heated AXIS Vest 2.0 in Black | Size Small
