End your day on a luxurious note by slipping into a deep slumber with the Slip Silk Sleep Mask. Designed to accompany the Slip Silk pillowcase, the mask is made from the same patented SlipSilk™ durable mulberry silk. The mask offers breathable temperature control, shields your eyes from external stimulation by completely blocking out light and movement, and provides your delicate eye area with protection from creasing and wrinkle-causing friction. Featuring a 100% silk filler, outer/inner layer and silk coated elastic band, this durable mask is perfect either for overnight use, as a travel buddy or for those afternoon naps. Slip Silk Sleep Masks are created under stringent regulations with certified non-toxic dyes.
