    French leakproof underwear

    This was my second time ordering from knix they always do what they say they do and the new ones are no different. I haven’t tried any other because I know these work very well.

    Awesome underwear

    These fit like a glove and are soft as silk. I use them for bladder leakage and they work wonderfully for moderate leakage. I’m so glad I found knix!

    Comfortable fit but light

    I love these No-Show French Cuts. They're so comfortable yet they wear really light. Feels like I'm not even wearing underwear. I keep buying a couple packs at a time when there's a sale or I have a coupon so that I'll have enough supply soon to replace all my cheap cotton ones. Thank you KNIX!
