The Jack & Jones Dongo Socks come in a pack of 10 and feature a simple casual or business look. They are part of the Eco program "Better Cotton Initiative" (BCI). The environmentally friendly production of a high-quality fabric made from 72% cotton, 26% polyester, and 2% elastane characterizes these durable socks. The material can withstand machine washing at 40 °C, but the socks should not be bleached or dry cleaned.
