Persona Socks are made from Egyptian cotton, which is softer than regular cotton, more durable and kinder to your skin - what's not to like?! Egyptian cotton is the perfect material for luxury socks and once you've tried these super soft premium socks, you won't go back! All socks are ISO 14001:2005 accredited, using yarns from suppliers who are OEKO-Tex trademarked (i.e. no chemicals which are harmful to humans, the environment or animals in their yarn).
