In addition to powering the expanding line-up of 18-Volt cordless tools and accessories, Makita 18-Volt batteries can help you keep warm in cold, harsh job site conditions. The 18-Volt LXT Cordless Heated Jacket has a power source that accepts Makita 18-Volt LXT and 18-Volt Compact Lithium-Ion batteries for up to 37.5-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 Jacket has 3 heat settings to adjust to changing weather conditions and 5 core heat zones (left chest, right chest, back, and both pockets) for optimum heat distribution. With 5 pockets, including a zippered chest pocket, left and right side pockets, a sleeve pocket, and battery pocket, your cell phone or other accessories are always within reach. 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 fluorescent heated jacket has silver reflective tape accents, polyester shell for increased wind and water resistance, and a soft fleece-lined collar 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. This heated jacket meets ANSI107 Class 3 requirements for use in work environments.
