Finding a quality sleep mask is a real challenge. Often the only masks available in stores are cheep "travel masks" or girly, sequined ones found at an accessory shop. Both of which are low-quality, and barely adequate at keeping out light. On a recent hunt to replace my current mask, I found Lights Out masks on Amazon. What a treat! Finally, a high-quality, adult-sized sleep mask, that does the job right. My husband and I both use one, and have found our sleep quality drastically improved.
Three things that make these masks stand out from all the others:
1. Soft, foamy fabric for comfort.
2. A concave shape inside that does not directly touch your eyes, allowing for natural REM when you sleep.
3. A velcro-adjustable strap, which allows for a perfect, customized fit.
Lights Out sleep masks come in blue and black
Update On Oct 16, 2009: We have owned these for nearly 2 years, and still wear them every night. The blue mask has faded slightly, but otherwise both masks are in great condition. I am very VERY happy with this purchase!
