I have several of these suits in different sizes with my kids in use and am completely satisfied. The suit must fit snugly so that the water inside in it can warm up to body temperature and thus isolate. Especially for normal to lean children one finds difficult matching suits and the price is amazing! The size 2 (2 years) fits perfectly in an average-sized child and even next summer. The suits are stretchy and very comfortable to wear. Easy to put in a dry state. If the suit is wet or damp the child, it is tedious ... Super for cool days on the beach or in the outdoor pool :-)
