Breton striped socks in versatile all season colors can be dressed up for work or dressed down with denim. The Breton stripe is named for the classic striped garments worn by mariners from Bretagne, France. The yarn and layout (fit) for the Breton stripe is the same as our rugby stripes and is one of our most popular for a good reason - they are the perfect medium weight - not too thin, not too thick. The spandex and lycra both help the sock stay up and hold to the leg and fit a variety of foot sizes really well.
