Powered by M12 Redlithium battery technology, Milwaukee M12 heated Axis jackets use carbon fiber heating elements to create and distribute heat to the chest, back, and shoulders. A one-touch LED controller allows users to select from three heat settings, delivering ideal heat for any environment. The new quick-heat function allows users to feel heat 3X faster than previous jackets and market competitors. Hybrid construction featuring the new Axis Ripstop polyester provides a lightweight, compressible design that can be used as an outer shell or a mid-layer jacket, and provides wind and water resistance to survive the elements.
