Splash About Baby Wrap Thermal Wetsuit Size: L (18 months - 30 months) This is a thermal wetsuit. My child didn't like the Velcro, so it was only used once a week for two months. It was worn over swim diapers. There are some fold wrinkles. There are also some pills on the piping if you look closely. It is clean with no noticeable stains. We have a dog, so there is a possibility of hair adhering to it. Thank you.
