From the people

The Best!

These are the BEST women’s underwear you will find! They fit perfectly, are made of organic fabric, are expertly sewn, are cut generously, do not ride up, launder beautifully, and they don’t wear out! You must try them!

Best underwear ever

The quality is fantastic and the comfort is better than anything I have ever worn. I love my Thunderpants and am recommending them to all my friends.

The BEST full coverage underwear

I’m so glad I found these! Really the best full coverage underwear around. The cut is really flattering, and I can tell the fabric will hold up through many washes.
