At the heart and soul of every SmartWool product is the amazing fiber we use: nature’s finest Merino wool. Used properly, we think it’s the best fiber available for outdoor apparel — manages moisture better than cotton, smarter than synthetics and more comfortable in any weather condition. In our hands, it becomes extraordinary. We’re wool geeks, there’s no way around it. For over 17 years we’ve been combining the latest in innovative design, technology and construction with the best wool nature has to offer, and it’s this expertise and experience combined with our passion for mountain sports that makes our products so unique.
