The Wamsutta Dream Zone Sheet Set is constructed with 1000-thread-count PimaCott fabric, which is made from pure Pima Cotton grown in San Joaquin Valley, CA. The set features a traditional stripe design and is known for its softness, durability, and vibrant colors thanks to the long and dense Pima Cotton fibers. The pillowcases have a European envelope design to secure the pillow in place and cover the end neatly. It also has a Boxer Fit with wide elastic for a snug fit.
