    Saved me

    I recently ran a 10k race wearing a pair of these. I had just gotten my period and was wearing a tampon, but let's just say, there were some issues during the race, and I knew the tampon was not holding up. I was worried about what I was going to find when I finished the race, but this pair of underwear did its job and saved me from embarrassment and a mess. I am so grateful and amazed by how well they held up. I'm buying more right now. These are the best purchase!
