    Mom loves them

    My Mom loves Knix. She is able to wear with protection from leakage without all the bulk of depends. Her cloths look nicer and she is able to cross her legs.

    She feels more feminine.

    New style for me

    I love the feminine look of this style. Im a big fan of Knix but this was my first purchase of this style. I love it. My advise? Get adventurous and try something new.

    Not at all what I expected

    Feels like a diaper— not at all like period underwear purchased in the past. Didn’t realize I couldn’t return unopened merchandise. Will be donating.

    No coverage in front and prone to leaks.

    While the back coverage and feel of the fabric is excellent the liner doesnt come high enough in front, even though I went a size up. It leaks in the front for heavy days,flooding episodes

    These are at the right time

    I really appreciate the full coverage. The only complaint is you need to wash before wearing. It make the material more pliable
