First-Layer Warmth, Bulk-Free

The Women's Quarter-Zip Heated Baselayer Top is built for cold-weather activities where warmth starts with 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. A 2-zone heating system covers the upper and lower back, while the quarter-zip neck and raglan sleeves keep the fit flexible and easy to move in. Worn with the Heated Baselayer Bottoms, it becomes a complete heated base layer set that helps create warmth where you need it most.

2 Heating Zones (Lower Back, Upper Back)
