Powered by our 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. Our quick-heat function allows our 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.
