It’s a very nice product, but it is not for kids as young as 3, as stated. My kids are 3 and 4, and these are too large and leave big gaps at the sides of their face and let water in.
These are the first goggles I've bought that don't leak. Ok, once, but that was because I wasn't careful when I put them on.
Effective glasses, UV protection. They make a good impression, just the straps are too short.
