Is it comfortable for back sleepers? Side sleepers? Belly sleepers?

The Manta Pro Mask is the best sleep mask we’ve ever made and it was created to ensure your utmost comfort regardless of what type of sleeper you are. 

The whole mask is super lightweight so it sits gently on your face as you sleep on your back. For side and belly sleepers (which make up about 74% of the population), we used a C-shaped foam for unbeatable belly/side sleep comfort. Since there’s less material on the temple, your head would sit flat on your pillow. Furthermore, Pro’s eye cups feature a smart “air bubble” that expands to keep light out when needed and compresses flat when you lie on your side. This gives you complete blackout sans the bulkiness so you’re comfortable all night long.
