Powered by M12 REDLITHIUM battery technology, Milwaukee M12 heated quiet shell jackets use carbon fiber heating elements to create and distribute heat to the chest, back and front hand pockets. A one-touch LED controller allows users to select from three heat settings, delivering perfect heat for any environment. The new quick-heat function allows users to feel heat 3X faster than previous jackets and market competitors. Featuring the new Realtree Edge pattern for use in wooded environments, quiet shell stretch polyester reduces noise from movement and provides wind and water resistance to survive the elements.
