The Raffy Sweat Socks from Rototo are made from a soft cotton pile and are modeled after vintage sweatshirts. Each sock is knitted from a cream coloured Raffy yarn which is an uneven yarn produced by blending 25% cotton waste in long staple cotton. To maintain the unique uneven feel, the yarn is slowly spun at Japanese factories with a spinning method that has not been changed for over fifty years. The 'R' for Rototo is inlaid on the side in navy with cut boss knitting to resemble a felt patch on a sweatshirt.
