Milwaukee® M12™ Heated Women’s Jacket: Powered by M12™ REDLITHIUM™ Battery Technology, the redesigned Milwaukee® M12™ Heated Women’s Jacket features an optimal women’s cut and new heating zone locations. The jacket integrates (4) carbon fiber heating elements and advanced fabric-layering technology to distribute and maintain heat across the back, collar, and pockets. Wind and water resistant, the versatile soft shell construction keeps weather out while high-loft insulation and a brushed thermal lining hold heat in to maximize warmth and reduce the number of layers needed in cold weather conditions.
