Base layers

Your active lifestyle should not be stopped by the cold weather. Our men’s base layers are here to help. From tops to bottoms, casual to athletic, Smartwool’s men’s merino wool base layers support whatever activity you participate in with extreme comfort & warmth. Our thermal merino base layer thermal is lightweight & made to maximize thermoregulation & breathability in high-intensity activities, all while providing a classic, stylish look. We take great pride in creating warm, comfortable clothing for outdoor activities & our quarter-zip merino wool base layer is proof of that. Made with our Merino Sport yarn, this jacket combines the power & benefits of Merino wool with durability & the fast dry times of polyester, making it perfect for performance. We keep this same spirit of ingenuity & performance with our mens base layer bottoms. Our joggers for instance, are made with 100% Merino wool, ensuring comfort. The waistband is also covered in Merino wool, which reduces chaffing & itchiness. Making them perfect to wear for jogging or any athletic activity. Looking for something to throw on top of these base layers? Be sure to check out our men’s wool jackets for those days where it’s so cold that a base layer just isn’t enough. Not cold enough for a jacket? Try some of our wool sweaters and hoodies that are stylish, yet can keep up with you no matter the activity.
