Product Details
The Smartwool Men's Classic Thermal Merino Base Layer 1/4 Zip Shirt is built for warmth, comfort, and performance during cold-weather adventures. Crafted from 100% responsibly sourced Merino wool, it naturally manages sweat, resists odor, and regulates body temperature to keep you comfortable in changing conditions. A slim fit follows the body's contours for a streamlined feel, while flatlock seams and offset shoulder panels reduce chafing during movement. The 1/4 zip design allows for easy ventilation and layering versatility, making it ideal for skiing, hiking, running, or any winter activity. As one of Smartwool's warmest base layers, this top combines function with classic style, ensuring reliable performance from first chair to last step on the trail.
