How it works

THINX definitely eliminates the need for panty liners, and will make a great back up to your tampon or menstrual cup. Some do choose to wear THINX on its own, but no one knows your flow better than you, so you’ll be the best judge of what works!

How it works

Well, every pair of THINX has a top layer that wicks all liquid into the über thin absorption layer right beneath it, so that you feel super dry. This way, you can wear 'em all day long (i.e., no, you don't have to change them during the day, no, they don't feel like diapers, and no, it's not like sitting in your own blood). Boom.

How it works

"I start wearing my THINX when I think I'm getting close to starting… My first day or so is pretty light, so I'll wear them on those days with nothing else. Then once it gets heavier, I wear a tampon and THINX, but that's usually only a couple days, then for the last few days that are light, I do just THINX again."
