Great product

My daughter loves the feel of these panties. She wants nothing to do with pads so they are perfect. No leaks and they last the entire school day.

So Comfortable!

I always hated wearing pads, they just felt so yucky and wet. I never wanted to use tampons either. I saw these, and at first I thought that they were too expensive, but once I got them I realized they were worth every penny. They are so comfortable, and so thin yet still super absorbent! They felt dry and clean all the time while wearing these. I definitely recommend them!

Better than the original.

My daughter didn't want to try these but I bought some just to see what they felt like, turns out she LOVES them more than the originals. The fabric is so soft and they absorb so much. They fit her tween body just right and are true to size. I wish I had these when I was a tween.

Comfortable protection

I am a larger woman, so the leakage protection did not protect me far enough back, however the middle area was well-protected and had no leaks for an 8-hour medium flow day

Love it!!!

Love my new Cotton Modal Super Leak underwear. I couldn’t believe how effective they are. I was able to wear them from 6-8 hours on my heavy days. I bought this

For my self, and I’m 41! I love everything about it! And I need more.
