Second pair I've bought! It did not fail me this time either. I did not feel gross wearing them at work and honestly hate having to put on a pad to wash them. These are awesome. They shipped them the same day I bought them and I will be buying a third pair whenever I can!

I have nothing but good things to say. now I have several versions form Heralogie and cannot decide which I like best. The bikini is sexy but for tight pants would recommend a full panty which will not show

These underwear are amazing! I have a heavy flow and these are truly magical. I wore them just as is and did not have to think about staining or changing a pad/tampon. If you are interested in sustainable period care, get them now!!!

I've been looking for period undies for a while, and these are so worth it! These look the same and seem to work the same as the most popular period underwear brand. The price on these are a huge bonus, I hate how other brands increase price based on absorbency. I love the inclusivity, too!
