At Collegien we are committed to positive social and environmental impact! Sustainably made from super soft long-staple Egyptian cotton, blended with a bit of man-made fibres for stretch-fit, each pair of socks combines comfort, colour and durability. We believe that our socks will become staples in people’s closets and can be passed down. We select only the best GIZA 45 LS Egyptian cotton, for its exceptional qualities. It is one of the rarest and most luxurious types of cotton available. Moreover, all the yarns we use have received the Oeko-Tex Standard 100 certification. Our garment-dyeing process confers extra softness and durability to our items, and complies with REACH standards for the protection of human health and the environment.
