CoolMax sheets boast a high quality hand and provide excellent moisture management for a superior comfort level. The 200 thread count material absorbs perspiration through the fabric, where it quickly evaporates, allowing the sleeper to feel cooler and more comfortable throughout the night. Fits mattresses up to 18" deep. Set includes 1 fitted sheet, 1 flat sheet and a pair of standard or king pillow cases (twin 1 case).
