Our wool goods are made from USA-grown Merino, traveling from Oregon to the Carolinas for processing and knitting. Our Repreve recycled poly is manufactured right here in North Carolina from locally collected post-consumer water bottles. DeFeet socks come with a 5-year warranty. If you are not satisfied with your product, we will replace it.
