    Perfect fit, lightweight fabric that is soft and comfortable; you can barely feel them yet at the same time feel secure with the leakproof protection.

    As advertised.

    If you have a larger belly like me, these are the perfect underwear. They cover the bulge and you don't feel like your hanging over the top. They keep me dry and comfortable as well. They are truly no-show. You can wear them under any garment and know that the panty line won't show.

    I do like them, but not as much as other others in different material or style

    These are great underwear functionally however they seem to be a lot smaller in the waist than the rest of the underwear. I ordered my regular size, but they are a bit more snug in my waist than normal. The rest of it seems to be fine. I’d go back to a different style. I usually buy high high waisted which these are in my regular size. It’s just that they are more snug.

    Best underwear ever!

    This is the most comfortable pair of underwear I have ever owned. The best part is that they are truly light leakproof and I am doing my part by saving the environment and money on pads!!

    Thank you knit
