used for my 1 year old daughters'' swim lessons @ the local YMCA. Helps keep her warm in the pool, which is usually 82 degrees. Lightweight, dries quickly after I put it in the swimsuit spin dryer @ the YMCA. Doesn''t become malodorous after use. My daughter appears to be comfortable in it and does not mind putting it on for swim lessons. 2T is slightly big for her small physique (20lbs & 32 inches tall), but I''m hoping to use it through the summer, fall & winter this year.
