We've gone through several wet-suit "shorties" for our daughter, now 15. Several we received from other "kid boats" who's
children had outgrown them and several we passed on ourselves. They do wear quickly, however, so two or three cycles is about all one can expect. They are important however, particularly gloves and booties, as there are some mean and nasties in tropical
water and
kids tend to be a little less careful than adults.
I also suggest you carry a squeeze bottle filled with ammonia in your medicine chest to treat stings from jelly-fish (sea nettles) and fire
coral and the like as well as alcohol, peroxide and lots of neosporin together with water-proof "new-skin" You'll need them.
