Poor quality Chinese fake. Head hole absurdly small- the medium size can’t even remotely fit over head (and i wear children’s bicycle helmets as my head is exceptionally small).

This was used in combination with a wet suit while swimming off the west coast of Scotland. It worked very well, helping to avoid the awful "brain freeze" that accompanies being in cold water and allowing longer time in the sea.
