GO FAR, FEEL GOOD – SMARTWOOL EST. 1994: Born on the slopes of Colorado, Smartwool is driven by the belief that time outside is time well spent. We harness the natural performance of Merino wool to keep you comfortable, so you can go farther, feel better, and experience more—every step of the way. 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.
