All of our 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 perfecf material for luxury socks and once you've tried our super soft premium socks, you won't go back! We also know that being ethical is important, which is why we're proud to say our manufacturer is ISO 14001:2015 accredited and only obtains its yarn from suppliers who are OEKO-Tex trademarked (i.e. suppliers who do not use any chemicals which are harmful to humans, the environment or animals in their yarn). We also do not use any plastic in our products. Our socks consist of 80% premium Egyptian cotton and 20% mixed fibres (14% polyester/polyamide, 3% spandex and 3% elastic). Men's UK 6.5 - 11.
