Introducing our luxury level jersey knit sheet sets made of 100% Supima cotton. Supima is the acronym for superior pima cotton. Pima cotton is the best cotton grown in the United States and Supima is the best of that harvest. The cotton fibers are longer, softer, and stronger than regular cotton.We make these sheets just a little heavier than our regular sheets to showcase how special they feel and we have only added a touch of color to accent the most sophisticated room decor.
