Why you need this sleep mask Blocks all light to help you fall asleep faster and stay asleep longer — ideal for naps, overnight rest, and travel. Gentle on skin and hair to prevent irritation and facial creases while you sleep. Lightweight, portable, and durable so it works at home, on planes, and anywhere you need complete darkness and comfort. Key benefits True 100% light blocking: thick, contoured padding around the eyes creates a pitch-black environment that keeps out sunlight, streetlights, and electronic glow. Skin-friendly materials: premium, hypoallergenic mulberry silk, ultra-fine microfiber, and breathable cotton reduce friction, feel cool and soft, and suit sensitive skin. Comfortable, pressure-free fit: ergonomic shape conforms to facial contours, providing a snug seal without pressing on the eyes or temples. Adjustable and gentle strap: elastic or Velcro closure fits all head sizes and is designed to avoid pulling hair or irritating ears. Portable and multi-functional: lightweight and foldable for travel; suitable for sleeping, long-haul flights, daytime naps, meditation, and relaxation. Easy care and lasting performance: most masks are machine-washable while retaining softness, shape, and light-blocking ability; silk masks recommended for gentle hand-wash.
