In addition to powering the expanding line-up of 18V cordless tools and accessories, Makita 18V batteries can help you keep warm in cold, harsh job site conditions. The 18V LXT Cordless Heated Vest has a power source that accepts Makita 18V LXT and 18V Compact Lithium-Ion batteries for up to 28 hours of heat (with BL1850 battery, sold separately). You can also keep your portable electronic devices charged-up with the convenient on-board USB power port. The Heated Vest 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. Size 3XL.
