The last thing you want as you're drifting off to sleep is a mattress protector that crinkles and crunches with the slightest movement. Safeguard your investment and sleep soundly with the GhostProtector, our cooling mattress protector with a completely waterproof barrier and allergen-eliminating technology. Most mattress protectors are made of plastic, with a reputation for overheating during the night. Not ours. The GhostProtector uses a soft knit fabric that wicks moisture away and provides quiet breathability so you stay cool, calm and collected.
