No worries about leaks

I used the underwear on my heaviest flow day for a full work day and was never worried about leaks.

DEFINITELY WORKS

I been using knix underwear for a couple of years now for my periods and I honestly love them but I always wanted to be able to not have to use other period production with the underwear. BUT with these I can and it honestly made my last period so easy and I didn’t have to worry! My periods are usually heavy too
