COLD WEATHER BASE LAYER. Increase your comfort level with this 100% Merino wool crew. Add one of our best base layers for cold weather to your winter wardrobe and experience the difference the next time you go skiing, hiking, climbing, or biking.
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.
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 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 — a back body seam wraps to the front for a body-enhancing fit while a flatlock seam construction minimizes chafing.
GO FAR. FEEL GOOD. From wool socks to base layers for men, women and kids, we aim to provide the highest quality apparel for your outdoor adventures with a commitment to environmental sustainability, racial equity and inclusivity.
It's the little things that make up the big ones. And we really need to sweat the details to make sure that we're taking care of the big picture. To us at Smartwool, the big picture is simple to identify — defeat climate change and make sure everyone has access to the outdoors. But it's the small choices we make every day that will make sure we get there. For us, it doesn't just start with our product, but with our community and our planet. That's why all of our Merino wool products — from hiking, running, and ski / snowboard socks to base layers, mid layers, outdoor apparel and more — come with our guarantee to remain committed to environmental sustainability, racial equity and inclusivity, plus frequent artist collabs to stay on the forefront of high quality, sustainable fashion. Once you experience our Merino wool, you'll realize that a better future is possible. Go far. Feel good.
