Milwaukee® M12™ High Visibility Heated Jacket: Powered by M12™ REDLITHIUM™ Battery Technology, Milwaukee® M12™ Heated Jackets integrate (3) carbon fiber heating elements and advanced fabric-layering technology to distribute and maintain heat across core body areas. A 300-denier, wind and water resistant shell keeps weather out while improved insulation and a thermal fleece lining hold heat in to maximize warmth and reduce the number of layers needed. Featuring 3M™ Scotchlite™ reflective striping and a zip-on hood for added jobsite versatility, the Jacket meets ANSI/ISEA 107-2010 Class 3 certification.
