• COLD WEATHER BASE LAYER. We've updated this fan-favorite with new colors and a new fit to improve functionality while enhancing aesthetics. Add this cold weather base layer to your winter wardrobe and experience the difference on your next adventure.
• SLIM FIT. Designed to meet the demands of outdoor adventuring, this slim fit crewneck shows off a slimming silhouette while offering unrestricted movement through the arms and chest.
• CLASSIC THERMAL MERINO. Ideal for cold-weather activities where warmth and breathability are crucial, this midweight fabric used a Merino wool construction that helps move moisture away from skin to keep you warm and dry.
• WHY MERINO WOOL? Thinner and softer than regular wool, it's easy to wear next to skin. Each fiber transports sweat away as a vapor (we tested it ourselves) and regulates body temperature to keep you cool in summer and warm in winter.
• FUNCTIONAL FEATURES. Go far, feel good with thoughtful tech to keep you trekking comfortably — interlock knitting enhances breathability, thermoregulation and moisture-wicking while flatlock seams minimize chafing for greater comfort.
