cpaphat is an ultra-soft liner that cushions your scalp and protects hair from pulling, tangling, or breakage caused by CPAP straps and friction. Designed to be worn under most masks without affecting fir or seal, the lightweight fabric helps wick away sweat and moisture, keeping you cooler at night while also adding a soft barrier between your skin and headgear to reduce pressure, redness, and iritation. Comes in a pack of 2 cpaphats.
