    Love them

    I have bladder leakage and have to wear pantyhose liners every day. Sometimes it’s just not enough. The Knix underwear gives me the confidence to know that I don’t have to worry. About that anymore. I love them.

    Best leakproof on the market

    I have tried other brands and find knix the most comfortable and truly no-show. I buy a few different absorbencies just in case(i.e. coughing from a cold requires heavier) . The colors are fun and the fabric feels wonderful on the skin.

    Best underwear ever!!

    I bought the moderate absorption for light bladder leaks. They are so comfortable and sneezing or coughing don’t worry me anymore. !

    Works well for leak proof and doesn’t show underwear lines

    I like these underwear for medium leak protection. The thin fabric on the sides allows for minimal underwear, lines under dress pants.

    Terrible Fit

    You need a specific body type for these to fit.

    I’m a tall person with a long torso, and yet these are hiiiiiigh waisted. If you have a shorter torso, these might just reach your boobs.

    The gusset is also too wide, and they end up cutting into the inside of my legs. If your thighs touch, these won’t be comfortable.

    So unless you’re a tall model with a thigh gap, I highly recommend the ‘boyshort’ version instead of this style.

    (I also still have to wear pads with these, but that’s a minor issue compared to the fit).
