If you know of anyone that has trouble getting to sleep on planes, or even at home, this highly rated sleep mask would be a great stocking stuffer.
It’s silk all the way around, doesn’t use velcro that can get caught in your hair, and keeps its plastic fastener in the back, rather than on the temples which can bother side sleepers. Just be sure to clip the $2 coupon to get it for $8 at checkout, so your wallet can rest easy.
