Knitted on a rare, old-fashioned knitting machine using un-dyed, organic cotton, the Low Gauge Stripes are uniquely solid and thick due to this special, low gauge knitting machine used in their construction. Don't let there slim shape fool you, these fit nicely as the knit has a lot of stretch while resisting sag. There is a time for bright white socks, and there is a time for a look that is more au naturale. These socks are here for you in such times. With the highest content of unbleached cotton (93%) in our entire line of socks, they are sure to please those folks with an aversion to wool or acrylic.
