Nidra Contoured Sleep Mask for Men Women – Zero Pressure Fit, Light Blocking Eye Shade for Side Sleeping & Travel – Black, Small Size

I have been using this on planes to sleep and it effectively blocks out light and is easy on the eyes as it does not press on them at all.

They have changed the design from 3 years ago so the elastic is adjustable but now goes over or behind the ear. A side sleeper like me will find that uncomfortable.

Ya usaba un cubre ojos sencillo pero el diseño de este producto es aún mejor. Vale cada peso invertido. Cuando olvido ponérmelo, no duermo igual. Recomiendo 100%

Basic elastic band around the head causes pressure over the top of my ears. Hard foam does not fit well across nose. Sleeping on side displaces mask and lets in light. After a single wash in a wash bag, it starts to fall apart.

I have a small head so I ordered the small size and it fits great. It blocks out the ambient light and fits comfortably when side sleeping. Material is soft and flexible to ensure a good fit.
