The Earth Therapeutics Ergonomic Sleep Mask is a contoured, light-blocking sleep mask designed to promote deep, restful sleep for frequent travelers, light sleepers, and anyone sensitive to nighttime brightness. Thoughtfully engineered with a specially contoured eye area, the mask curves away from the eyes and lashes rather than pressing against them, allowing for pressure-free relaxation and comfortable wear—even when used with overnight eye treatments. The interior surface that rests against the skin features a smooth 100% silk lining, selected for its naturally soft, gentle feel and its premium, skin-friendly touch. Inside, a lightweight polyester fill provides cushioning and structure, helping the mask maintain its ergonomic shape while delivering a snug, comfortable fit that supports a blackout effect. Extra-cushioned edges are designed to fit closely around the eyes and nose, enveloping the eye area in calm, comfortable darkness without irritation. The outer shell is crafted from a Lycra® fabric blend (80% polyamide, 20% polyurethane), chosen for its pliant feel and streamlined profile, while an adjustable elastic strap made from 100% nylon allows for a customizable fit that sits smoothly without bunching or disturbing the ears. Care instructions: Hand wash in lukewarm water with mild soap and allow to air dry naturally. Do not machine wash or tumble dry. Not tested on animals. Paper packaging is made from 100% FSC®-certified materials, and the window is made from recyclable PET.
