    I wish I had this when I was younger

    What a great buy. I love that I can feel confident, that it won't leak, and that it's better than using other hygiene products for my period days. I honestly don't know how many days I have left with this cycle of life, but it really helps to know I get to be comfortable during perimenopause and help Earth a little with less pollution.

    Leakproof No-Show panties

    Great product! I tried Everdries and returned the rest because they were uncomfortable and the fabric was flimsy. That's when I came back to Knix. Since I needed more protection from bladder leaks than Idid before, this time I ordered the super Leakproof ones and they do the job!

    Best period underwear

    I was very happy with my period underwear. They are comfortable and do not show under my clothes. The protection level is very high as well.

    Nighttime coverage

    My daughter had seen this product so I ordered a pair for her to try. She already wears and loves her other Knix period underwear. She thinks this new pair is amazing for night time!

    I like it.

    It is comfortable and works well so far. Compared to my pants size medium, I learned to order these small as these are more stretchy and it stays on better this way for me.

    Love it!

    I have mild incontinence after having my son and these underwear mean no more pads! They are comfortable and fit great, I can't wait to buy more.
