Our heated TOUGHSHELL jacket is powered by our powerful M12 REDLITHIUM batteries. Each heated jacket uses carbon fiber heating elements to create and distribute heat to your chest, back and front hand pockets. A one-touch LED controller heats up the battery heated jacket to three heat settings, creating a comfortable heat for any environment or weather. This MILWAUKEE heated jacket has a new quick-heat function that allows you to feel heat three times faster than our previous jackets and market competitors. Like all of our other products, our jackets are built strong to last long with TOUGHSHELL stretch polyester delivering five times longer jacket life than our previous softshell heated jackets. The durable material also provides wind and water resistance to survive the elements whether you are on the worksite or enjoying the outdoors.
