Powered by MILWAUKEE M12 REDLITHIUM Battery Technology, the MILWAUKEE M12 Heated Hoodie provides HEAT BUILT FOR COMPLETE COMFORT. Using a one-touch LED controller, the advanced carbon fiber heating elements create and distribute heat to the chest and back. The Quick-Heat function allows users to select from three heat settings and feel heat 3X faster than market competitors. A hidden battery pass-thru pocket construction allows for front or back battery placement, increasing comfort and flexibility depending on the situation. Combining a durable cotton/polyester fleece and comfortable jersey lining, this hoodie provides a versatile three-season solution to keep heat in and not add bulk.
