Wall Street Duvet Cover Poplin Stripe Light Blue is a duvet cover from the Swedish brand Magniberg, made of poplin which consists of 100% Supima cotton. The fabric is woven from 300 threads which gives the poplin a crisp, dry and cool touch with a flat structure. The duvet cover has also been treated with mercerization to create an extra soft feel, but which also improves color absorption and wear resistance. As the name suggests, the duvet cover is part of Magniberg's Wall Street collection, which was inspired by the classic shirts of the 80s that were a common garment among the bankers in the financial district. Thanks to the quality of the fabric and the careful production process, this duvet cover is a sustainable choice that will last for years to come.
