See the size chart on the Siven web site – note these are the actual sizes of the top itself so go up a size if you are at all doubtful or don’t want a tight fit.

Order from I have some in stock otherwise I will order when we need a few. The price may go up because of the exchange rate and fixed delivery charge.

Note zipped key pocket at the back, DVO logo on the front and the club name in full down the back.
I can also arrange to resell out-grown children’s tops. Let me know if you have one to sell or would like to buy.
