    Fantastic for a first-time period underwear user!

    They fit awesome, I wasn't worried about looking like I was wearing a bulky pair of panties, and they absorb EVERYTHING. I have a very heavy flow and these worked like a charm on day one of my period. Definitely going to be buying more in the future! Goodbye, pads!
