These Work.

I was suspicious this underwear would meet its claims - holding about 8 tampons worth?! But OMG! This underwear WORKS. On my heaviest days, I’ll wear these from morning until bedtime and have never had one leak. I was literally SHOCKED! Even better they feel completely dry all the time! The only thing I’d say is they seem to fit slightly smaller than KT’s regular oh-no proof underwear, so I’d recommend going up a size.

Astonished

I purchased these for my teen. She started her period at a young age so I feel like we've tried every pad under the sun to find something that was comfortable and "didn't look like a diaper". Our biggest concern were the night leaks/overflow but I have to say, Knix did the job! I didn't expect for them to do so well! I was astonished! No leaks, no overflow. My daughter was very happy which makes me happy.

Game-Changer

This underwear has completely changed my period routine. I’ve always worn pads, but they’re uncomfortable, make me itchy and I’m looking for something more sustainable. Enter KT’s Super ‘Oh-No’ Proof underwear. They’re perfect for anyone looking for sustainable period protection. You can’t tell you’re wearing period underwear either. Super comfy and super absorbent! I can wear them all day with no leaks. I will definitely be buying more!

Why did I wait so long?

I bought these for my daughter. So far, they have been great. She’s not afraid of accidents & I’m glad she won’t go through what I used to go through. Washes great too. I wish the price was a little more reasonable but they are an investment
