    Love the additional capacity...

    Like the regular leakproof but with more capacity for longer days or more strenuous activities.

    Where were these when I was a kid!

    Surprisingly very comfortable and not bulky at all. I haven’t 100% tested the leakproof adequacy, stuck in my old ways. However very pleased, hoping they wash well and last for cycles to come.

    These are perfect

    We have 2 teen daughters in dance and always worried when they’re on their period. But no mishaps when they’re wearing these and they’re cute.

    Super leakproof no show bikini

    I have used all strengths and all cuts of Knix leakproof undies. I especially love the bikini! I won’t be without them ever! I absolutely love these products and will not buy anything else. Even super leakproof is beautiful and sexy! Bless you, Knix!
