Description
xDiscover cooler, crisper nights with the Mueller UltraTemp King Size Sheets Set. Crafted with breathable, moisture-wicking fibers, this six-piece collection helps move heat and sweat away from your skin, promoting a refreshing, more balanced sleep from the moment you slip under the covers.
UltraTemp Technology delivers thermoregulating, quick-drying performance. The lightweight knit breathes easier than heavy, tightly woven cotton and feels irresistibly soft against the skin—the kind of comfort that makes you linger between awake and dreamland. The set includes a fitted sheet, a flat sheet, and four pillowcases, all designed to stay smooth and comfortable after every wash.
