About Knix

Knix has established itself as a pioneer in functional apparel, focusing primarily on innovative leakproof technology. The brand is dedicated to creating products that make you feel comfortable and confident throughout your daily life. 

They have successfully challenged industry norms by openly discussing body positivity, self-acceptance, and eliminating stigmas surrounding women’s health issues. This approach extends across their product line, which includes a wide range of highly-rated intimates. 

You can explore everything from supportive wireless bras and comfortable sleepwear to their signature period and leakproof underwear. Knix is often celebrated for its inclusive sizing and commitment to making apparel for every stage of a woman’s life.

How to Redeem Knix Coupon Codes

  1. Select the Knix clothing you want to buy and add them to your shopping cart. 
  2. Click the "Checkout" button to go to the order summary page. 
  3. Find the box labeled "Discount code or gift card" on the right side of the screen. Enter your promotional code in that box. 
  4. Click the "Apply" button to use the discount before you finish your payment. 
  5. Check that the total amount in your order summary shows the new price with your savings.

Knix Returns and Exchanges Policy

Knix offers a satisfaction window that allows you to return or exchange most products within 30 days of the delivery date. To be eligible, the merchandise must be in brand-new, unworn condition with all original packaging and tags fully attached. Please note that original shipping charges are non-refundable should you choose to process a return for a refund.

When shopping the sale sections, it is critical to observe the posted discount percentage, as this dictates return eligibility. Any merchandise marked down by 30% or more is considered final sale and cannot be returned for a refund, exchange, or store credit. Items discounted at less than 30% are still eligible for an exchange or store credit, but not for a monetary refund.

If you are new to their period underwear, you can take advantage of a fantastic risk-free trial. This policy allows you to try one pair of leakproof underwear from your initial order for up to 30 days. If the size or fit is incorrect, Knix will gladly send you an alternate pair or issue a full refund for that specific item. If your order contained multiple pairs, remember to only open, wash, and wear one; all other unopened packages are only eligible for exchange or store credit.

I'm surprised to read all these…

I'm surprised to read all these negative reviews. I've been very happy with both the products and the customer service. Of course, I'm dealing with the Canadian company but it's hard to imagine why the US company would be so different.

Liberating

The period panties are incredibly comfortable and life changingly convenient. They have been completely reliable for me and no hassle to care for. I’ve tried several brands and this one has been best for me by far. It’s hard to think of any criticism. The fabric isn’t the coolest if you work out in them in the summertime, but they’re still fine and most importantly they work. I have many of their underwear and while none have completely worn out yet, after a few years the side and waist seams have started to split a bit in places. I’ve gotten plenty of use out of them but hate to toss any as I am attached to some of the limited edition patterns! I wish their bras had worked out for me similarly, but I could not find the right fit. I felt bad that I tried a few bras and none of them worked out. Their system was very easy to work with to resolve the misfit bra issue.
