Stop Trashing Your Period Challenge 🗑️

Can you go your entire cycle without using plastic?

Almost 6 billion tampons are bought annually in the United States alone. Add in pads, wrappers and other packaging, that is a lot of disposable period products filling up landfills. And while single-use plastics like straws and water bottles are being swapped for sustainable alternatives, we at Kt think it’s also time to break up with disposable period products… forever! 

Switching to period underwear during your cycle is an easy way to cut out single-use menstrual plastics like tampon applicators, pads, wrappers and other packaging. 

Sounds great, right? We absolutely agree. 


Kt, along with our big sister brand Knix, challenges YOU to try and go your entire cycle without using a single disposable plastic product. Using a mixture of ‘Oh-No’ Proof Underwear, Super ‘Oh-No’ Proof Underwear, and reusable pads, if needed. Shop period kits now.

We’re asking you to share your journey and encourage everyone you know to make the switch - for yourself, for the planet and for your wallet.
