We want to be transparent. In an effort to create the best quality product and keep our Cool Supima® sheets at a friendly price, we chose 100 percent Supima® cotton to make our sheets. While not organic, Supima® is one of the strongest and softest materials in the world. And we're not the only ones who think Supima® is great - the American Image Awards honoured Supima® as the Premium Fiber Brand of the Year in 2015.
