Women's 3-Zone Heated Baselayer Bottoms

Built for lightweight warmth and cold-weather layering, the women's Heated Baselayer Bottoms are a heated baselayer for the lower body, made for skiing, hiking, outdoor work, brisk walks or jogs, and everyday cold-weather wear — worn under pants or outer layers, or on their own as standalone leggings. This bottom uses a liner-free construction to reduce bulk and create a softer, more flexible next-to-skin feel. A 3-zone heating system covers the knees and core, while the streamlined fit makes them easy to layer under pants without getting in the way of movement. Worn with the 1/4 Zip Heated Baselayer Top, they complete a heated base layer set that helps create warmth where you need it most. Highlights 3 heating zones located at the left & right knees and core Soft brushed stretch fabric that feels smooth against the skin Wide high-rise waistband for a secure, supportive fit Flatlock seam construction reduces friction and chafing Ergonomic paneling follows the body's natural shape for a streamlined fit Reflective logo print at the back waistband for low-light visibility Feature Details 3-zone heating across the knees and core delivering targeted warmth to areas that stay cold during extended outdoor activity. Soft brushed stretch fabric that feels smooth against the skin, bringing comfortable warmth without unnecessary bulk. A wide high-rise waistband creates a secure, supportive fit that stays comfortable through extended wear. Flatlock seam construction reduces friction and chafing, making the baselayer easier to wear for long periods. Ergonomic paneling follows the body's natural shape for a streamlined, supportive fit that moves comfortably under outer layers. A reflective logo print at the back waistband adds subtle visibility when worn as an outer layer in low-light conditions.
