Tired of buying a sheet set and not use the flat sheet that you also paid for? Nautica is introducing an open stock fitted sheet. Here you can customize your purchase to buy only the items needed for that perfect night's sleep. The fitted sheet includes a 4 way fully elastic all around to keep in place, which fits mattress up to 18" (up to 15" for twin size). Love your pattern of choice? Nautica also has made it available in other product types including pillowcase pairs, sheet sets and even a duvet cover, all sold separately. The fitted sheet is constructed of 100% cotton and made with a percale weave for a crisp feel. Fitted sheets are machine washable for easy care.
