WHAT IS SUPIMA® OR PIMA® COTTON?

Supima cotton is the key ingredient in the Casper sheets.

Supima is one of the longest cotton fibers in the world. It’s 35% longer and 45% stronger than regular cottons, which means the fiber is even softer and more lustrous wash after wash. It’s a big part of what makes the Casper sheets naturally soft.

You can trace the cotton directly to the source. Supima is a trademarked name for textiles woven from 100% American Pima cotton and is only grown in Texas and California. The Supima cotton used in Casper sheets comes from a farm in California’s Central Valley.
