Benefits of Mulberry Silk: Silk absorbs less moisture which helps to keep your skin more hydrated during your sleep. As silk has a soft texture, it allows the hair to slide rather than tangle and knot which reduces the damage that can be caused over time. Silk is known for its hypoallergenic properties due to it being a natural fibre free of any added chemicals. Gentle, easy-to-adjust headband won’t tangle hair or snag pillow. The adjuster stays at the back of your head, not at your temples, which can be uncomfortable for side-sleepers. Fits comfortably with ear plugs and even with a CPAP facial mask. Fully adjustable strap from 15.8 inches to 39 inches, suitable for women/men/kids. A sleeping mask will assist in falling asleep quicker and also promotes a better quality, deeper sleep.  Ideal for insomnia, migraine headaches and dry-eye sufferers, as the breathable, natural fibres of hypoallergenic silk allows healthy oxygen in while keeping dry air out. Get the benefits of total blackout, whether at home, in a hotel or on the plane (where bright led light and dry air can be especially harsh). The perfect travel accessories to help keep you feeling rested and refreshed. Care instructions: Hand wash or delicate/silk cycle with a mild detergent and air dry or dry clean.
