    I am in Heaven

    So very happy to have found these leakproof underwear. I am 72, active with golf and workouts.

    Ordered my first 5 pairs size Large which worked out perfectly, just ordered another set of 5. I am 5’7” and weigh 150lbs. Hope this will help other women.

    Many thanks for a great product!

    Knix Underware

    I love everything about the underware. They are everything that is said about them. They do run a little small by one size so I would recommend order the next size up.

    I love my new Knix underwear.

    I love the underwear and the way it fits, but I just wish you had the padding in the rear end of the underwear on the French cut panties.
