COREBAY 3D Ergonomic Total Blackout Sleep Mask – Side Sleeper-Friendly, Pressure-Free Eye Cups, Soft Breathable Memory Foam with Adjustable Ear-Friendly Strap（Black）

Tired of waking up from light leakage or facial pressure while sleeping? Our 3D Ergonomic Total Blackout Sleep Mask is designed to solve every sleep discomfort, especially for side sleepers.​ Crafted with an upgraded ergonomic structure, it features a precision-cut nose bridge and 3D face-contouring design that fits snugly against your face—no gaps, no light seepage. Whether you’re dozing off at night or taking a midday nap, it blocks 100% of light to eliminate distractions, helping you slip into longer, deeper sleep without pressing on your eyes or facial skin.​ For side sleepers, the ultra-thin, flexible side panels are a game-changer: they hug your cheeks gently, minimizing pressure on your temples even when you shift positions. It works just as well for back and stomach sleepers, keeping light out from every angle so you can sleep undisturbed.​ The wider 3D eye cups are another highlight—they leave plenty of space for free blinking, unlike flat silk masks that press on eyelids or smudge eyelashes. No more waking up with creased skin or messed-up makeup; it offers zero eye pressure for all-night comfort.​ Made with slow-rebound memory foam and air-hole fabric, it’s soft, lightweight, and highly breathable. Your skin stays cool and fresh all night—no stuffiness, no overheating. The upgraded symmetrical elastic strap is fully adjustable: it stays in place without tangling your hair, and there are no annoying buckle loops to irritate your ears or temples. It won’t twist or slip off, even if you move around a lot, making it suitable for men, women, and kids.​ Before first use, simply hand wash with water below 40℃ for better softness. Skip bleach and ironing, and adjust the headband position to match your comfort and eye level—customize it to your perfect fit.​ Say goodbye to restless nights and hello to uninterrupted sleep. This isn’t just a sleep mask; it’s your ticket to deeper, more comfortable rest, no matter how you sleep.
