    Why take the risk of purchasing is no way to return or exchange? Wasted $38 for these

    Bought these for my teen and they are 1) so low waisted, who wants low rise on their cycle? 2) not so much a SHORT which she wanted for modesty and peace of mind on period but they are like a cheeky underwear 3)they ride up in the thighs when you walk. Of course they don’t allow refunds or exchanges so now I’m going to try to resell or find someone to share with. I seriously regret this purchase.

    A must for tween girls

    My girl is small so it’s hard to find period anything that fits. This fits her perfectly and provides great coverage. It is not bulky at all either. Will buy more.

    Go To Period Swim Short

    Love these swim shorts and mostly use them under board shorts. Never had a leak and never missed a day of water sports due to my period but I do plan well.

    Great coverage no leakage

    Absolutely great for my daughter. This is a no brainer for girls and women these days! Girls can feel secure and comfortable without worrying about tampons all summer long.
