    Great quality, discreet protection

    These are high quality and I like not filling up the landfill with all the disposable pads. I don't always trust the ads that are served up in games, but this one's a winner.

    The fit is great and they are very comfortable. They keep minor leaks from clothing.

    J’adore ces sous-vêtements!

    Je suis très contente de mon achat. C’est exactement ce que cherchais. Ces culottes sont super-confortables. Enfin, plus de protège-dessous irritants. Ils se lavent comme un charme et sèchent rapidement.

    C’est exactement ce que je cherchais! Merci.

    Leakproof

    Light Leakproof worked like I hoped they would! Yes, the cost is a little high, but I thought I would waste my money on the cheaper brands! Glad I bought from Knix!
