    Do not order up in size if you are in between or you will regret it.

    Great quality

    My son has lived in these so far this summer and won't wear any of his other swim trunks. With frequent pool visits and washed they are holding up great!

    Great trunks

    These are perfect for boys. The liner is like shorts and they are very comfortable.
