    Light and comfortable

    I personally find the higher absorbency thongs to be a bit more uncomfortable, but this one is light and thin enough to feel like regular underwear. Very comfy and still provides that little bit of absorbency for backup or lighter days.

    My new favorite thong

    This is a great light leak proof thong. Perfect for wearing under tight clothes and dresses that you don't want panties lines, with the added bonus of protecting your clothes on your light days

    Confortable, pretty and practical

    My first try with protection underwear. Very pretty, comfortable and not bulky at all. Less absorbent than I initially tought, but a good protection for low flow days!
