"Not a paid endorsement. Zero odor from owner of very sweaty stinky feet. Had them on 12-13 hours a day. Tried every name brand high dollar sock. They're now in the rag pile. Worth every penny. I'm out in winter in Michigan."

Fabric Content
Our socks are knit using a merino wool and bison down yarn, and the blend of that yarn itself is the 80% merino and 20% bison listed on our website. To create a sock that is durable, maintains its shape, and can withstand regular washing and wearing without matting, additional fibers—such as nylon and spandex—must be incorporated. Without these fibers, the socks would not stay up on the leg, provide the proper fit, or offer the longevity our customers expect. We’ve done extensive research on this and work with some of the best hosiery manufacturers in the United States to ensure the highest quality product.
Care recommendations
Care recommendations
For best results, wash your socks in cold water and hang them to dry. While we recommend air-drying, tests have shown that machine washing and drying will not damage the socks.
