I've used better sleep masks
First off, let's get the "100% natural" claim out of the way - unless that's the brand name, it's false. It's got polyester straps and plastic pieces, plus some sort of fill which may or may not be silk. So while the silk may be a "natural" fabric, nothing else about this mask is "natural."<br /><br />That aside, it's soft and the fabric is smooth. I find the fit to be very tight, even on the loosest setting, but I assume the thin, inexpensive polyester elastic will relax over time. The double straps give more adjustment options if you need that, but I find myself adjusting them to fit on top of one another so they're actually fitting like a single strap. Maybe because that's what I'm used to?<br /><br />Where it really fails is in light blocking. The cut and style are very basic and old-school, which means plenty of light comes through around the nose. I agree with another reviewer that this is very much like the airline eye masks they hand out for free, with the exception of the silk covering (but the airlines use a very soft polyester, so the feel is the same).<br /><br />Overall, there's nothing to really recommend here. I'll keep using my Lewis N. Clark eye mask, which is both cheaper and much better at blocking light, while still being extremely comfortable.
