Powered by M12™ REDLITHIUM™ battery technology, Milwaukee® M12™ heated hoodies use carbon fiber heating elements to create and distribute heat to the chest and back. A one-touch LED controller allows users to select from three heat settings, delivering ideal heat for any environment. The new quick-heat function allows users to feel heat 3X faster than previous hoodies and market competitors. Combining a durable cotton/polyester exterior with a waffle weave thermal lining, the hoodie provides a versatile 3-season solution to keep heat in and allow users to shed bulky layers.
