The Smartwool Women's Classic Thermal Merino Base Layer 1/4 Zip Shirt is a midweight thermal base layer designed to provide dependable warmth and comfort during cold weather adventures. Crafted from 100% ZQ Merino wool, it naturally manages moisture, regulates body temperature, and resists odors to keep her comfortable through long days on the slopes, trails, or running routes. The updated slim fit follows the body's contours while raglan sleeves and shoulder panels enhance mobility for unrestricted movement. Flatlock seams and a wraparound back body seam help minimize chafing, making this layer comfortable beneath jackets and backpacks. Finished with a convenient 1/4 zip for quick ventilation, this base layer is built to perform through every winter activity.
