As a natural fiber, wool reacts differently each time it is knit. This is one of the things we love about it most. Additionally, our hats are knit on hand-operated vintage machines. They are not spit out cookie cutter by a software design and modern electric computer machine. As a result of this, each of our wool hats is like a fingerprint, carrying its own special look and character. After a few wears, the hat, like a quality leather shoe, will break in and form to your head.
