The Temperature Regulating Sheet Set.
Using a fabric developed for NASA to help astronauts adapt to extreme
temperature fluctuations, these sheets prevent overheating or eliminate
chills to create an optimal sleeping climate. Imbedded in the sheets are
millions of invisible microcapsules that absorb excess heat when you
are hot and release the stored heat when you are cold, ensuring a
comfortable bed temperature and humidity. Unlike an electric blanket,
the microcapsules adjust independently to an individual's climate,
allowing two sleepers with different temperature preferences to remain
comfortable throughout the night. The 300-thread count blended cotton
fabric is impeccably soft and machine washable. Includes one fitted
sheet and one flat sheet, and pillowcases. White, Linen, Stone,
Cornsilk, Rose, Green, and Lake Blue.
