    Leakproof Boxers

    My daughter loves these. She finds them comfortable, feels confident they will not leak and will even wear them at a friends house at a sleep over. Glad there's an additional option for leak proof sleepwear.

    We have multiple pairs and will buy more when another colour arrives that she likes.
