Contoured Sleep Mask for Side Sleepers – Zero Pressure Fit, Light Blocking Eye Shade for Sleeping & Travel – Blue, Small Size

Very comfortable - this mask has a low profile so even if you sleep on your side it doesn't shift out of position that much (just a little, so it stays in place mostly). Deep eye cups so you don't feel it pressing against your eyes. It's also very light-weight so it's not very noticable - and it really does block out the light. When this wears out I'll definitely buy another Nidra.

Great with lash extensions

Mask quality is fine, but the edges all around are sharp, they scrape and cut into your face. Also, the sides of the nose piece are so tight they push in on your nose, very uncomfortable. I have a small face so it would be worse for a larger one.

Not a perfect fit, but very dark. I find it difficult to comfortably sleep on my side with this mask. If I sleep on my back, the mask is great.

Really nice. Plenty of space in the eye cup for blinking / eyes open. NO light leakage under the nose piece. (And I mean none - this is a big deal.) Adjustable elastic band was comfy, once adjusted. They are a bit "solid," in that they are firm foam, not a piece of fabric. So, that is something to keep in mind - if you're expecting a soft silk sleep mask, this is not it. If you want something that will block light while letting your eyes do what they do, this is for you.

I love my new Nidra Sleep Mask! I had never had a mask before, and spent a long time sorting through ads to find this one. I have a small head, and the small medium size is perfectly snug but comfortable. It offers plenty of free space for eyes and eyelashes, and shuts out all the early morning light in my bright bedroom. It also does not leave grooves in my skin even though I often wake up sleeping almost on my face. I would recommend this mask to anyone looking for a great night's sleep!

I like the sculptured nose cutout which the Bucky I have been using for years does not have. The large size would probably have been better for me (5'3", 128 pounds).

The material is cheap and the elastic head band is very thin and stretches out quickly. It does keep out the light when it is placed correctly but slides off while sleeping. I have only had it for about three days and ended up purchasing a different mask out of frustration.
