The Makita CJ105DZ is a battery-operated heated winter jacket designed for demanding outdoor work environments. This technical jacket features five strategically placed carbon fiber heating elements located on the chest, back, and lower back, providing consistent warmth in cold weather conditions. Powered by Makita 10.8 V (12 V max) lithium-ion batteries compatible with 1.5 Ah, 2.0 Ah, and 4.0 Ah models, the jacket offers flexible heating duration options. The intuitive touch controller located on the left chest allows for easy operation with three heating levels: high setting provides about 3.5 hours of warmth, medium setting lasts for 5.5 hours, and low setting delivers up to 14 hours of continuous heating with a BL1041B battery. Constructed from durable polyester material with wind and light rain protection, this jacket maintains its functionality in various weather conditions. The polar fleece lining ensures thermal insulation even when the heating system is not activated. Practical design elements include five pockets for storage convenience, with a special battery compartment in the left rear side pocket. The jacket features a stand-up collar and closes with a two-way front zipper for adjustable ventilation. Available in black, the CJ105DZ weighs 1.1 kg without the battery adapter and power source. The included 12 V max (10.8 V) CXT battery adapter allows seamless integration with Makita power tool batteries. For cleaning, the jacket is machine washable on a gentle cycle with warm water up to 30°C after removing the battery adapter. This heated workwear solution combines technical heating performance with practical outdoor jacket functionality, making it suitable for construction, maintenance, and other cold environment professions that require reliable thermal comfort during extended work periods.
