Your Makita 12V max CXT™ battery can help you keep warm in cold, harsh job site conditions. The 12V max CXT™ Cordless Heated Jacket has a power source that accepts Makita 12V CXT™ batteries for up to 14 hours of heat (with BL1041 battery, sold separately). You can also keep your portable electronic devices charged-up with the convenient on-board USB power port. The Heated Jacket has three heat settings to adjust to changing weather conditions. It has four pockets including a zippered chest pocket that is ideal for a cell phone or other accessories, as well as left and right side pockets and a sleeve pocket. The battery pocket is on the rear-left side, so it's out of your way but within reach for quick and easy access. The soft fleece-lined collar is tailored for increased user comfort, even when fully zipped-up. The knitted storm cuffs and drawstring waist provide a better fit to help keep the cold weather outside. It's part of the expanding 12V max CXT™ series, combining performance with superior ergonomics in a compact size.
