Supima

Supima is the top 1% of all cotton globally—only 1 in 100 cotton plants worldwide meet Supima's strict standards. It's grown exclusively in the United States (California, Arizona, Texas) because it requires specific climate, soil, and irrigation conditions unavailable elsewhere. Most retailers use cheaper standard cotton because Supima's limited U.S. supply and rigid quality requirements make it significantly more expensive. Threadmill's commitment to 100% American-grown Supima is why these sheets deliver exceptional luxury durability that lasts a decade.

Supima® uses extra-long staple fibers, making the sheets smoother, more durable, and less prone to pilling

Absolutely. It's naturally breathable and regulates temperature beautifully across seasons.
