We just bought these for my 9 year old (size 10 hoping to get some extra use). You are so big! The waist has nice elastic and has a drawstring for extra adjustment, but the length! They almost fit me and I'm a 5ft 2ft woman! They look decently waterproof. We have a pair of lined Jan & Jul pants for my 4 year old and they have been great water pants so far.
