Merino Wool is a natural fiber that's incredibly soft, moisture-wicking, and will keep you warm in the winter and breezy-cool in the summer. Bombas took this super yarn and blended it with a little bit of polyester and spandex to help perfect the fit of every pair, and create the built-in arch support so many feet now know and love.
