The Wamsutta Dream Zone Sheet Set is crafted with verified pure Pima Cotton from the San Joaquin Valley in California. It boasts a luxurious 1000 thread count and a timeless stripe pattern. Pima Cotton's long and dense fibers make it exceptionally soft, durable, and vibrant compared to standard cotton. The pillowcases feature a European envelope design to securely hold the pillow in place and neatly cover the end, while the Boxer Fit ensures a secure and comfortable fit with its extra wide elastic.
