What our customers say

  • ★★★★★

    This is the first time I've bought this kind of underwear and today is the first time I've worn them — honestly, they're perfect. You feel light, you don't feel any protection the way you do with regular pads, and I think they look good. Really, I'm very happy. I've ordered two more.

    Game-changing

    Extremely comfortable and very absorbent, even with a very heavy flow. I don't even need to change overnight! A revolution.

    I love them

    No bulky diaper feeling, especially when you move — you can't hear the fabric! You feel confident going out, or overnight.

    Excellent product

    Great product! I really recommend it to any woman who wants to feel at ease in her body.

    Really pleasant to wear and they work!! Sizing is spot on.

    Pretty, but…

    Pretty pair. I took an S but I find it runs smaller than the others. Shame.
