I got these for my six year old, they fit him with a little room to spare.  I was looking for something more substantial than the magic glove or the mittens that come with character sets for young kids.  Though they obviously aren't waterproof, I can see they will carry him through a season of snowball throwing without soaking through.  I tried them on myself and found them to be very comfortable and warm.  Naturally the convenience of convertible style and a reasonable price caught my attention.  I would recommend this product, you may want to buy more than one pair.
