Milwaukee M12 heated jacket. Designed for optimal heat retention and fit. Integrates 5 carbon fiber heating elements and advanced fabric-layering technology to distribute and maintain heat across core body areas. For added versatility, 2 heat zones (back and chest, lower pockets) can be adjusted independently to provide the right amount of heat. Rugged wind and water resistant shell keeps weather out while insulation and a thermal fleece lining hold heat close to the body and reduce the number of layers needed. On and off the jobsite, jacket provides up to 6 hours of continuous heat per battery charge to withstand the harshest outdoor conditions. Utilizes M12 REDLITHIUM battery technology. M12 battery holder is stored in a sleek back pocket that can expand to fit M12 XC batteries and all M18 batteries with additional M18 USB (universal serial bus) charger accessory. Also includes a fuel gauge to check battery life and built-in USB port for charging portable electronic devices. Jacket is washer and dryer safe. Includes jacket, M12 REDLITHIUM battery, charger, and battery holder. Replacement battery available.
