Women's 2-Zone Qtr Zip Heated Baselayer Top

The Women's 2-Zone Quarter-Zip Heated Baselayer Top is built for cold-weather that needs warmth from the first layer. It is a lightweight heated baselayer made for active cold-weather routines where warmth needs to stay close to the body without adding bulk to ensure it works quietly under a jacket, vest, or shell, bringing flexible core comfort to skiing, winter hiking, walking, jogging, and long days outdoors.
