These ORGANIC COTTON 100% RIBBED SOCKS are made of only cotton, with no backing yarn like nylon. The socks are knitted with fine 3 x 1 rib knits to ensure a good fit, and will not slip down without feeling uncomfortably tight. There is no backing thread, so they are gentle and comfortable to wear. Available in three colours.
Natural Black: “Gobaishi” dyeing is a natural dyeing process made from gall, which is produced in rhus javanica. It contains a lot of tannins which gives it a deep gray colour that is different from black. It has antibacterial properties that meet JIS standards so it can wrap around your feet comfortably.
Gentle machine wash in a laundry net, dry inside out.
