About Knix
Knix is a Canadian intimates brand selling leakproof period and bladder-leak underwear, wireless bras, shapewear, swim, sleep and activewear, plus teen and men's lines; founder Joanna Griffiths says she invented leakproof underwear.
For Canadian orders, the number that matters is $100 CAD: spend that after discounts, before shipping and taxes, and standard shipping is free.
Knix sorts its leakproof underwear by absorbency, from an Essential tier with no absorbency through Light, Moderate and Heavy up to Ultra, and an online quiz helps shoppers pick between them. Styles run from high-rise and French-cut briefs to thongs, boxers, boyshorts, Thigh Saver shorts and the Dream Short series. The bra range takes in maternity, nursing and surgical recovery bras, and there's a separate maternity and postpartum section.
The teen line covers period underwear, sleepwear, swimwear and activewear, while the men's underwear uses pouches in three absorbency levels. Recent drops include an ACOTAR™ x Knix collaboration. Beyond its online shop, Knix runs stores in Toronto, Vancouver, Ottawa, Calgary, Edmonton, Winnipeg and Mississauga, plus one in New York, and members of its free Club Knix program earn points toward rewards.
Does Knix offer free shipping?
Yes. Canadian orders over $100 CAD ship free, counted after discounts and before shipping and taxes.
How long does Knix shipping take?
Orders are packed within 1-2 business days, up to 4 in peak periods; Friday orders after 1PM ship Monday, and NWT, Nunavut and Yukon pay a $20 delivery fee.
What is Knix's return policy?
You get 30 days, with return shipping paid by Knix through its portal; bras, shapewear and Thigh Savers can come back even after wear and washing.

How to use a Knix discount code
- Knix codes, the Club Knix birthday code included, are pasted at checkout.
- Many of its savings need no code at all, because multi-buy pricing such as 15% off three or more pairs of underwear and 20% off five or more is tied to quantity.
- Several Club Knix rewards can go on one order, and Rewards Shop products can sit alongside a separate code such as a referral code.
- Watch how deep a discount runs, though: anything cut by more than 30% becomes final sale, so you lose the usual return.
More ways to save at Knix
- Club Knix is free and pays back in points, early access to drops and sales, and a birthday code for a free Light Leakproof No Show Bikini, valid 30 days.
- A higher yearly-spend tier adds free standard shipping on all orders.
- The referral program pairs well with Rewards Shop items, since the two can be combined.
- Bra shoppers can buy two to save 10%, and the Last Call section runs up to 60% off, though markdowns that deep are final sale.
Knix questions, answered
Can Knix underwear be returned after wearing?
Underwear and pads go back for an exchange or store credit only. The exception is a first leakproof pair, which can be worn and washed for 30 days and refunded at the item price.
Can Knix discount codes be combined?
Several Club Knix rewards can be used on one order, and Rewards Shop products combine with a separate discount code such as a referral code.
Are Knix sale items returnable?
Items discounted more than 30% are final sale, so check the markdown before buying from Last Call.
Does Knix ship to the US?
Knix ships to the US, with US orders priced in USD. Other international orders under $150 USD pay $25 USD and take 10-25 business days.
When do Club Knix points expire?
Points expire after 12 months without a purchase, so one order within that time keeps them active.
