The word Supima comes from Pima (derived from the indigenous American tribe) and superior. Less than one percent of the cotton annually produced in the world qualifies as Supima. It’s exclusively grown in the southwestern United States. The extra-long fiber length makes Supima incredibly soft. The long, dense fibers of Supima absorb and retain dye better than most other cotton ensuring vibrant, long lasting color. Super-durable and stronger than traditional cotton, Supima is less likely to pill or shrink.
