Knix is a high-tech women's underwear start-up that perfectly pairs performance fabrics with stylish designs. Founded in 2012, the ladies underwear brand has quickly become an online retail success story, with women of all ages sharing the love for the ultra comfortable intimates brand.

Knix was started by real women, for real women. By listening to women’s needs and hearing what they love — and hate — about the current underwear selection on the market, Knix founder Joanna set out to create quality intimates that fit well, look good and are made for normal, everyday women can enjoy no matter what their shape or size. Knix also offers loungewear so you can relax in style and ultimate comfort.


Knix’s Build a Set option lets you select 3 sets of underwear, one bra and a pair of socks. You choose your colour and select your size. You’ll also get a cute athletic bag with your set.


Every year, Knix gives undies to women’s shelters to help give back to the community and help women in need. It lets you know you’re doing something good for yourself and someone else when you support Knix. Watch for Knix coupon codes that you can use to add a discount to your online shopping bag.
