Thread counts vary widely across navy sheet sets. Common counts shown in listings include 200, 300, 400, and 1000.
Listings commonly show two weaves: percale and sateen. Percale is described as crisp, breathable, and cool; sateen is described as smooth, silky, and lustrous.
Most navy sheet sets include a fitted sheet, a flat sheet, and pillowcase(s). Twin and Twin XL sets usually include one pillowcase; Full, Queen, and King sets typically include two pillowcases.
Percale weaves around a 200 thread count are described as crisp, breathable, and cool. Higher-count cotton sateen weaves are described as silky-smooth and lustrous.
