    Moderate absorbency leaked

    I purchased these for my daughter. I had previously purchased in store, then again online. The sales associate recommended moderate absorbency because it was her first one. They leaked. At first I thought maybe she worn them for too long. But after making her wear it for only two or three hours it still leaked.

    I suggested to start your teen out with heavy

    absorbency. This made my child feel more comfortable and confident during her cycle.

    Love them!

    These cute underwear are so comfortable and of such good quality. They last and look just as good two years down the line from when they have just been bought. The Knix company is run by Canadians and the company has such good ethics and customer service, truly helping their customers when they need anything. Thank you Knix!
