We all sleep better when it's dark.
The top side of this comfortable sleep mask is turquoise blue Batman cotton fabric, the back side is your choice of soft black fleece, soft navy blue cotton knit (like a t-shirt) or smooth black satin. Inside is a dark layer to block light. The soft, wide elastic is black, shiny on one side. Pattern placement will vary, the smaller sized masks will be as shown in the photo with Batman, but without the yellow Batman logo (it's just too big to fit right on a small mask).
