I didn’t think underwear could make such a difference.
Honestly the comfiest underwear I’ve ever worn. The bamboo fabric feels amazing.
Super soft, breathable, and it actually stays in place. I’m switching over completely.
I got 8 for cheaper than a pack of 3, and they're 10x better!
They fit really well, even after a few washes. Great quality.
