So what is Infinity Cotton? It’s a proprietary blend of 85% extra-long staple Egyptian cotton and 15% extra-long staple Indian cotton. Less than 20% of all the cotton grown in the world is long staple and only a very small percentage of that is considered extra-long staple. Typically it’s reserved for only high end apparel garments. We’re using it to make our Infinity Cotton duvet cover set. Sateen duvets have a unique woven construction that puts more of the actual yarns on the surface of the duvet cover. That special construction gives sateen that lustrous look and feel. Our proprietary construction puts twice as many yarns on the surface to give you an even SOFTER hand feel. You’ve never experienced a sleep experience as luxurious as this. The set includes 1 duvet cover and 2 shams.
