Huub swimming , tri wetsuit for kids it says size 10 for 10year old kids i would say it would fit 10-11 lovely suit - not worn top of the range suit thermal lined the reason we are not keeping it - my boy is pretty skinny and the legs on the suit a a touch big for him - So i would say it will fit a lad with good solid legs ! selling for 1/2 the price we paid for it .
