One distinguishing feature of the Flou sheet collection is the excellent quality of the fabrics - all are natural, luxurious and shrink-proof. The stability and brightness of the colors are extraordinary, even after numerous washes. There is a interesting choice: from the highly-resistant 100% pure American combed cotton (yarn density 32 warp x 32 weft per sq.cm.), the wonderful sheen of the 100% Egyptian cotton satin (yarn density 75 warp x 36 weft per sq.cm.), or Egyptian linen from untreated cultivations and exclusive Indian silk.
