Our Milwaukee M12 Women's Heated AXIS Vest delivers HEAT BUILT FOR LIGHTWEIGHT DURABILITY. Powered by our M12 REDLITHIUM Battery Technology, this lightweight and durable vest features an advanced heat technology system utilizing carbon fiber heating elements and Quick-Heat functionality, distributing heat 3X faster than market competitors to the chest and back. A hidden battery pass-thru pocket construction allows for front or back battery placement, increasing comfort and versatility. Five exterior pockets ensure your essentials are always within reach. With re-engineered AXIS Ripstop polyester fabric, our vest prevents tears from spreading while keeping heat in and not adding bulk. The compressible, wind and water-resistant design can be used as an outer shell or mid-layer vest depending on the situation.
