I have a son thats 12 and is 80lbs 4ft 8in tall and I would like to try and find some wadders for him. I am not trying to buy anything new as we all know how fast kids grow but he has taken a interest in fly fishing and during the summer could wet wade. Now that is colder he won't be able to do that so I would like to keep him fishing with me. I think a womans small would work to. So anyone have some or know where some cheap ones are???
