These are the smooth, luxuriously soft sheets made from 100% Pima cotton grown and harvested in the United States. The Pima cotton used in these 300 threadcount sheets is grown and harvested in California, where the state’s rich soil yields impeccably soft yet durable extra-long staple fibers that each measure over 1 3/8". The superior fineness of Pima's staple allows more fibers to be spun into a yarn of a given thread count, resulting in a softer hand, a flowing drape, and more brilliant color acceptance. Pima also lends greater durability to fabrics made from it, making these sheets more resilient than lesser ones that combine coarser upland cotton or Pima/upland blends. Made in the heart of the original Cotton Belt, the sheets have classic hem stitching sewn with 10 stitches per inch. Includes one fitted sheet, one flat sheet, and two pillowcases.
