We use certified Egyptian Cotton for our 500 thread count sheets and duvet covers. Egyptian Cotton is extra fine long staple fiber, this allows us to weave a super smooth sateen fabric that is softer, stronger and more luxurious than ordinary cotton sheets and duvet covers. Our Egyptian Cotton 500 thread count sheets and duvet covers will give years of superior comfort and durability. This collection also comes with matching duvet sets that will complement any bed!
