I don't like the traditional snorkel masks and thought for the price point I'd try this out. There was no information I could find on sizing, but I'm a woman and the S/M size worked well. The mask did not allow water in on the sides and did block the water coming into the top of the mask when submerged. I didn't experience fogging. Overall I think the mask provides good visibility. However, at one point the curve of the mask and the way the light was hitting it created a small reflection which was at the corner of my eye and a little distracting. Super pleased overall with this mask though.

Just keep in mind that blocking the water also means no new air is coming into the mask. It will start to get hot/suck on your face if you're continuously trying to breathe in air at that point. I did take the mask off a couple of times to breathe easier. I was warned some people have experienced a little light-headedness with this type of mask.

The snorkel gear seems good but it’s not kid’s size, the mask and tube is the same as adult size I have.
