At SmartWool, they make smarter, more capable products so you can stay out longer. Merino is the highest performing fiber known to outdoor athletes, and SmartWool has taken it to a whole new level. They start with the body in motion. How it moves. How it sweats. How it cools. Then they put Merino where it matters most - next to your skin. And then they make it even smarter - adding a body enhancing fit, mapped ventilation and innovative fabric technologies. Mix it all together and you've got incredibly comfortable socks, apparel, and accessories for all season performance.
