Swimming diaper cover/diaper.

Can be used with or without a diaper during swimming activities due to the padded liner inside. We loved this one as it has velcro & tie closures. He has grown out of it so onto bigger design. ☆☆☆Tag reads Medium but for reference my son is a 25lb 1.5 years old wearing 12 months so I suggest that it is between 3 & 12 months for use.
