Originating in the South Western United States, Pima cotton is most closely comparable to Egyptian cotton, with which it shares long-fibered tensile strength and an amazingly soft feel. Pima cotton was first produced in Peru, but has been named after the Pima tribe of Native Americans who began cultivation of the plant in the US. The desirability of Egyptian cotton led to attempts by the US to grow it in the Southwest, but the resulting crop varied slightly from its Egyptian cousin. The superb absorbency of the material does mean that stains are easily formed, and the fabric should be treated with stain guard whenever possible.
