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. Combining a durable cotton/polyester exterior with a waffle weave thermal lining, the hoodie provides a versatile three-season solution to keep heat in and allow users to shed bulky layers.
