About Knix
Knix creates underwear, bras, and swimsuits for women at every stage of life. They're famous for their leakproof period underwear that actually works. We like shopping at Knix because their products are comfortable and they last through many washes. You'll find activewear and starter kits on their site, too. Their bras don't have uncomfortable underwire but still give you support for daily wear, exercise, and lounging. Knix makes managing periods easier with reusable pads and first period kits that take the stress out of unexpected leaks.
Need help with your underwear order or want to know more about using a Knix promo code? Head to Knix.com and check the Customer Care section at the bottom of their page. You can also use their chat feature or email them at [email protected].

Frequently asked questions about Knix
Bundle up for better deals on underwear
Stock up on leakproof underwear for the whole week and watch your savings grow. We love this discount because the more you buy, the more you’ll save. It makes sense to purchase this way because most periods last five to seven days, so it’s perfect to have one for each day of your flow.
Our recommendation is to take advantage of their bundle pricing:
Buy 4 pairs and get 15% off
Buy 7 pairs and get 25% off
In our opinion, buying the seven-pair bundle gives you the best value per pair while setting you up with enough underwear for daily wear when it's that time of the month.
