    Teen loves it

    I wasn't sure if my 17 year old was going to like them or not, she LOVES them- especially in the summer months. They make her feel less worried about having a leak in her cute summer rompers.

    Great fit and comfort

    I have bought several brands of period underwear and these are by far my favorite. They fit perfectly and are super comfortable. I will definitely be buying more.
