    Decent but prefer others ones I bought

    The ribbed fabric is not as comfortable as others I purchased. While a decent product, nott favorite. I did not like the matching bra at all.

    So comfy!!

    These are my favourite leakproof undies so far! They’re super soft and comfy and you don’t feel like you’re wearing a mega pad all day. Highly recommend for lighter days or paired with a period cup or something.

    Super comfy, love these for sleeping

    Ultra flattering and super comfy. I love wearing these for sleeping even when I don’t have my period. The leakproof pad is soft and not bulky. Add the matching tee!

    Great

    Love these underwear. Soft and comfortable to wear.

    I wore them traveling and they triggered the sensor when I went through security’s When I went for additional screening, the highlighted region was the leakproof material on the underwear.

    I will be ordering more of these underwear, but won’t wear them if I’m going through airport security.
