At the heart and soul of every SmartWool product is the amazing fiber we use: nature’s finest Merino wool. Used properly, we think Merino wool is the best fiber available for outdoor apparel — it manages moisture better than cotton, is smarter than synthetics and is more comfortable in any weather condition. In our hands, it becomes extraordinary.
Merino wool is the most dependable fiber when the only thing you can count on is a change in the weather. It’s year-round, breathable, and naturally resists odor. Plus, Merino wool doesn’t itch like traditional wool. Now that’s one amazing fiber.
