Our Luxury Sleep Mask offers superior comfort and a great sleeping experience. Crafted from 100% bamboo with a soft sateen finish, it helps to block out light and provide total darkness, ensuring restful sleep and improved alertness the next day. These sleep masks provide all of the great benefits of our OUIDA bamboo sheets - eco-friendly, hypoallergenic, and moisture-wicking. They are perfect for those who suffer from allergies or have sensitive skin, as they resist dust mites, bacteria, and other allergens.
