Most people agree that cotton is a marvelous fabric for use in almost anything, from shirts to sheets. When you shop for high quality cotton items of any kind – including bed linens, you will often keep seeing two terms over and over again: Supima and pima. Both relate to cotton, which leads to an obvious question. What is the difference between Supima and pima cotton sheets?

There are a number of differences between the two, but the most important thing to understand is that the term Supima is a branding vehicle, it is not a type of cotton. Supima cotton is made up only of pima cotton fibers that have met some exceedingly exacting standards. In fact, the name actually says it all.

No doubt at some point, maybe at school, you have seen dreamy looking images of fluffy cotton plants growing in a far-off field some place. And although from a distance all cotton plants look fairly similar, they are actually quite different from one another.

Pima cotton is one of a family of cotton plants known as extra-long staple cottons. Another very well-known member of the family is Egyptian cotton.

However, although it originated in Peru, most of the world’s supply of pima cotton is now grown in the US, and it is named after the Pima Indians, a migratory tribe who brought it with them when they arrived in what is now the Southwestern United States. You will now find pima cotton fields dotted across Texas, Arizona, California, and New Mexico.

Extra-long staple cottons are considered superior to other cottons because their fibers are longer. Longer fibers result in a cotton fabric that is softer, stronger, and more durable. Inside each fluffy cotton bud, extra-long staple cotton has individual fibers that measure at least one and three eighths of an inch in length, a measurement that is 50% longer than other cottons.

Pima cotton sheets in general are an excellent bedding choice that is strong, long lasting, easy to care for and will wash easily. The fact that you can tumble dry pima sheets without shrinkage is a big care plus as well.

The choice between pima sheets and Supima branded sheets often comes down to personal preference and budget. If buying US made goods is important to you then the Supima label guarantees you that you are. It also serves as an assurance that the fibers used to weave the fabric were some of the best available.

The Supima mark is a very prestigious one in fabric industry so the association simply does not allow inferior fibers to make the cut. That being said, pima cotton itself is an excellent choice, simply perhaps because of the cotton’s natural properties that are then transferred to the fabric created. So, if you find that pima sheets without the Supima brand mark are a better fit for your budget or are more readily available then you can still be assured you will be buying great sheets.
