Light weight, soft, smooth. Can trap heat so relax and cool down before use. Adjustable strap fits all, but can sit low on ears causing discomfort. Blocks most light but shifting around can cause gaps around the nose.

I use a sleep mask every night for sleep and this is the best one I've found besides the ones sold by Burt's Bees years ago. It is very soft and the nose baffle enables total darkness. I like the one strap so my hair gets less messed up in the morning.
