We got our sock machines set up in May of 2019, and hit the ground running. We knew our customers wanted a sock for every occasion, with heights and cushion levels for all activities. By combining our historic textile knowledge, and using what we learned after redesigning our classic sock styles, we were able to envision a brand new sock collection that could truly meet your needs.
We dialed in our yarn selection, using a combination of merino/nylon as the main body of the socks. These yarns deliver a high merino wool content, with the extra durability of nylon.
We have packed in huge quantities of wool next to your skin, using the synthetics only as needed to improve fit and durability.
Stretch nylon yarns are light enough to keep the merino content high while giving shape and fit to the sock. Lightweight plating also adds durability to high wear zones on the heel and toe.
Great warm socks. After wearing boots all day I come home and slip these on. They are so warm and comfortable.

Well constructed socks. I would buy them again. They keep my feet warm.
After years is Cold Weather Army training, I know a good sock when I see it. Bought a pair for my son-in-law, who participates is all sorts of winter activities in Maine. "Best sock I have ever owned, " he told me. I guess this old dog has some tricks to share with the young generation.
