Why Supima
Supima — short for Superior Pima — is among the rarest cotton in the world. Grown exclusively in the United States, it accounts for less than 1% of global cotton production. Its extra-long staple fibers produce a fabric that is exceptionally soft, remarkably strong, and resistant to pilling over time. It is the cotton of choice for the finest bed linens in the world's leading hotels. It is what UpsideLuxe is made from.
