Powered by M12™ REDLITHIUM™ battery technology, the Milwaukee® M12™ 3 In. 1 heated jacket combines technology and toughness to redefine layering on the jobsite. Pairing a heated hoodie with a heavy duty wind/water resistant outer shell provides ultimate warmth, versatility, and durability. The inner layer uses carbon fiber heating elements to create and distribute heat to the chest and back. Both pieces utilize GridIron™ 900 denier Ripstop polyester in high wear areas to outlast 12 oz cotton duck workwear by 3X against abrasion and tearing. Also featuring tarnish resistant metal zippers, and riveted, reinforced storage pockets the 3 In. 1 heated jacket is built to survive jobsite conditions in any weather.
