The Makita CJ105DZM is a battery-heated work jacket designed for professional use in cold environments. This heated jacket provides up to 14 hours of warmth on the lowest setting with a single 12V Max 4.0 Ah CXT battery. Three preset heat levels can be selected via chest-mounted controls with LED indicators. The heating system features five strategically placed heating elements—two on the chest and three on the back—for optimal heat distribution. Made from windproof and water-repellent polyester fabric with fleece lining, this jacket offers protection in harsh weather conditions while maintaining comfort. The included CXT battery adapter has an additional USB port for charging mobile devices. Convenient storage options include two side pockets, a chest pocket, and an inner pocket, all secured with zippers. The battery connection is conveniently located on the side of the jacket, and the front zipper can be opened from both the top and bottom for easy access. Technical specifications include a 10.8 V operating voltage, three heat levels (high, medium, low), and a machine-washable design that is dryer compatible. Operating times vary by heat level: approximately 14 hours on low, 5.5 hours on medium, and 3.5 hours on high with BL1040/41B batteries. The jacket is available in black and features a men's cut, suitable for work environments that require reliable heat protection during extended outdoor stays.
