Powered by M12™ REDLITHIUM™ Battery Technology, Milwaukee® M12™ Heated Hoodies use carbon fibre 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 quick-heat function allows users to feel heat faster than previous generations of M12™ Heated Hoodies. 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. Product includes an M12™ Power Source.
