About Knixwear

Knixwear Underwear Review

Knixwear is a Canadian lingerie brand for women. The following Knixwear underwear review provides an in-depth look into the company and its products to ensure you make the right purchase decision.

Overview of Knixwear

Knixwear Underwear Review

Knixwear is a company that strives to make the challenging aspects of everyday life more graceful and stylish. They provide bras, underwear, and other sports attire for women of all sizes. 

Whether you’re looking for a sports bra, and everyday bra, or a maternity bra, Knixwear has you covered. They offer consultations on getting that perfect fit via email or in-person by appointment. Their selection of bras and underwear are advertised in a purposeful way, making it easier to find the perfect bra for almost any outfit. 

Joanna Griffiths began her journey into Knixwear by inventing underwear to prevent leakage for women. She continues to lead the brand from Toronto, Ontario.

Knix bras and underwear are designed for women who don’t want to worry about any leaks from working out, breastfeeding, bladder issues, etc. and don’t want to have any unnecessary discomfort in their lives. 

This Knixwear underwear review found benefits and downsides to the brand:


  • 10% off your first purchase
  • Products are easy to wash
  • 30 day returns for Knixwear bras, even if the bra has been worn or washed
  • Knixwear’s Instagram gallery gives an enhanced view of their products by allowing customers to share how their Knixwear bra and underwear look in reality


  • Knixwear bras and underwear value function and quality over appearance, minimizing their selection to mostly plain colours and a few designs
  • Knixwear bras take time to mold to your body shape, so your bra will be too tight for the first few wears
  • Shipping outside of North America takes substantially longer
  • Above average pricing

Knixwear focuses on the following core values:

  1. Finding the perfect bra and underwear size for each customer. Knixwear provides detailed instructions on how to measure yourself for a Knixwear bra and offers fitting appointments. 
  2. Making Knixwear bras and underwear as functional and as comfortable as possible. For women looking for a sports bra, a bra for breastfeeding, or a bra for comfort—Knixwear is determined to give their customers comfort and satisfaction.
  3. Ensuring their customers are completely satisfied. They offer exchanges and/or store credit within 30 days. 
  4. Empowering women of all ages and sizes. Knixwear bras offers up to a G cup, which is a rare and difficult-to-find size.

Knixwear bras and underwear showcase the brand’s determination to raise physical confidence among women.

Knixwear Sports Bra Review

This Knix Catalyst Sports Bra comes in violet, black, steel grey, and a limited edition pattern. It may seem expensive at $98, but the quality proves itself: the Catalyst outperformed over 800 bras it was tested against. Easy to wear, this Knix piece molds to your body, supporting your breasts and keeping things comfy. Knixwear bra reviews gave this sports bra a 5 star average, making it a stellar workout choice. 

Knixwear Evolution Bra Review

The Evolution Bra is a reversible wireless bra that comes in black, beige, grey, and a limited edition colour for $68. The bra’s lack of seams and 4-way stretch fabric allows it to fit the shape of your body. This piece provides all-around comfort, supportive without the need for padding. The Evolution Bra also has an average review of 5 stars, but with limited reviews to consult compared to the Catalyst.

Knixwear Leakproof Nursing Bra Review

Knix’s nursing bra comes in just 2 colours, black and beige. Its leak proof padding makes breastfeeding less of a hassle and the fabric is made extra stretchy for the intense body changes mothers must go through. It has five adjustable latches for just that purpose. For a decent price of $68 and with an average of 5 star Knixwear bra reviews, this leakproof bra is up for the challenge.

Knixwear Underwear Review

Knixwear designs underwear in thong, cheeky, bikini, high rise, high rise thong, and short styles. This Knixwear underwear review takes a look at some of the brand’s most popular designs.

Thigh Saver Short

The Thigh Saver Shorts are exactly as they sound—say goodbye to thigh chafing. These Knix underwear shorts come in black and beige for a fair price of $39. This underwear is seamless and made with a comfortably stretchy fabric. Thigh Saver Short may not come in a wide variety of colours and designs, but they save your thighs for a reasonable price.

The only negative aspect would be that since the underwear covers the thighs, they may only be wearable with dresses and high-waisted pants. When it comes to Thigh Saver Short, they will function as a buffer for your thighs so long as you wear them with enough coverage. With multiple 5 star Knixwear underwear reviews, the Thigh Saver Short is a popular product in its category.

Essential Thong

Knixwear’s Essential Thong is one of the most diverse products found on their website. With a variety of designs and colours, the Essential Thong is a must have. For a fair price of $23, this is by far one of Knixwear’s most reasonable underwear offers.

Stylish and functional, the Essential Thong has it all. It is quick to dry after a sweaty workout, seamless, and extremely soft. No panty lines, no sweat marks, no problem. The stretchy softness of this Knixwear underwear line is simply essential for any athletic ensemble. With consistent 5 star Knixwear reviews, the Essential Thong is thriving. 

Leakproof Boyshort

A Knixwear underwear review found that the Leakproof Boyshort is a very popular product in its category. With even more designs and colours than the Essential Thong, this Knixwear underwear is both stylish and helps prevent leakage. For a generous price of $27, this extremely absorbent Leakproof Boyshort is sure to help any woman with bladder issues and periods carry on with their day, without having to worry about the state of their underwear.

This piece is seamless and can contain up to 3 tbsp of liquid without leaking. The built-in liner is very thin, making it almost indistinguishable from non-leak proof Knix underwear. With over a thousand 5 star reviews, Knixwear’s Leakproof Boyshort is a bestseller.

Knixwear’s Leakproof collection is also available in thong, cheeky, bikini, high rise, high rise thong, and short styles.

Actually, I found this to be the most uncomfortable bra I had EVER worn. It felt like wearing a plastic bag. Secondly, for a company that advertises that it’s Canadian, it is manufactured in China.

Asked by Patricia L Doyle (2 years ago) Reply

Just bought two of the thigh saver underwear, the shorter and longer lengths. Both are uncomfortable to wear as the waistbands roll down and gradually the whole things slips down. It requires constant yanking up. Money wasted as I can’t wear these items.

Asked by Cindy (2 years ago) Reply

I bought 3 pairs xl and 3 pairs 2x high rise underwear. The website says they fit snug at first. I usually wear Hanes cotton xl, so I wasn’t sure if the xl would be large enough. The xl are soooo big, the leg holes hang off my butt, and I can pull the underwear up under my bra. I am 5’8”. I washed them when they arrived and I am wearing the first pair for 7 hours??? The gusset does not cover my rear end. I have to pull them up at the back and push the gusset in between my cheeks so I don’t leak when I lay on my back??? You should offer a gusset 11 or 12 inches. A long Kotex is 10 inches. How is this product guaranteed leak proof?

Asked by Susan Carlesso (2 years ago) Reply

My leakproof underwear are falling apart! The crotch seam came opened up at first, and now the whole edging has come away from the crotch panel! These are not dried in the dryer, but hung up to dry! Is this common? XL is what I wear, and it is comfortable and looks very nice under my slacks, but are these defective?

Asked by Karla J Sheeley (2 years ago) Reply

Not attractive, and hideously uncomfortable underwear. What a waste of my money given I ordered 8 pairs, only opened and broke the seal on one of the packages and yet they will not accept return on others. Why do they waste the packaging and resources for packaging to seal them if they still will not accept a package that has not been tampered with. Bad for the environment with their clown size carbon footprint. As far as answers for their policy, they have none.

Answered by Marly Kendrick (1 year ago) Reply

Yes! I wanted to exchange my unopened packs of underwear for a different cut. I used their sizing guide and measured myself and trusted their tools and the underwear still didn’t fit so now when I want to exchange them for a different cut or size….No dice! $128 down the drain.

Answered by lindsay (1 year ago) Reply

the underwear stretches out A LOT. they will fit REALLY SMALL when you get them. to break them in wear them to bed for a few nights. once they fit nicely DON”T WEAR THEM TO BED as they will keep stretching out then be too big. I don’t know why they don’t explain how their material works better on their website…

Answered by Terri S Fisher (1 year ago) Reply

HORRIBLE company!!!!! I just had to throw away $96 in underwear because they were too small and wouldn’t let me exchange for larger size!

Asked by Heather (1 year ago) Reply

I was very excited to purchase a bra from you after reading an article and seeing your ads however I have changed my mind as I was very disappointed to see that once again a so called “Canadian” company has its products produced in China. Ughh. Shame. Shame. I am making a conscious effort to avoid anything not made in Canada. )

Asked by Florence W. Millett (1 year ago) Reply

I do not see your size chart! I wear a size 16 dress, 38” waist, and 41” hips.
I wear size 10 Hanes underpants. What is your size for me?

Answered by Terri S Fisher (1 year ago) Reply

Girl…..DO NOT ORDER!!!!!! I even went up a size (from their size chart) just to be safe and they are WAY too small! They won’t exchange or refund on underwear! I just threw away $96 in underwear!!!! Stay FAR away from this shady company!!!!

Knix packaging
Asked by Sasha (1 year ago) Reply

Love the sustainable packaging my Knix order came in. Who does Knix use for their packaging solution?

Best bra ever!
Asked by Nicole P (1 year ago) Reply

I ordered 2 wing-contour bras and when they arrived I quickly changed into one. I can’t believe how comfortable and how flattering it is! My breasts lifted where they should, felt like I gained a cup size. No side boob, I can move my arms better. I can’t wait for them to fit me perfectly. Don’t be discouraged by the tighter fit feeling. The website clearly states the more wash and wear the more it contours to your body. I showed all of the women at work and they were all impressed, emailed the link give $15 get $15. Thank you!

Does knix support 36GG?

refused to refund my birthday money while saying they have no suitable bra for me
Asked by Belinda (1 year ago) Reply

I received a knix gift certificate for my birthday. First attempt with KNIX was my own money. I followed their sizing and bra way way too tight and there were not enough band hooks. I returned for a refund on my credit card. Was happy with the refund process that time. My second try was using my birthday gift card I bought the next size up and a different style. Still a lousy fit that allows my breasts to travel all over the place, even just working a desk. the cups (if you can even call them that) are way to small despite what their sizing suggests and they didn’t get bigger with 2 weeks of wear. They said they don’t have a bra product that fits me at the moment. I also bought a pair of underwear. The underwear fit is very big and far too tall. As a previous review said I can pull them all the way up to my bra with fabric to spare. I’m only 5ft tall. I paid part credit card/part gift certificate. They will only refund what went on my credit card. $12. The rest of my birthday gift is toast. I’ve tried two styles and two sizes plus underwear. I don’t recommend this company’s products.

Asked by davette (1 year ago) Reply

I bought one of your panties. The absorbant section was so short that they are worthess. It looks like you do not accept returns evem if they are not worn. Money down the drain and I will be shopping esewhefe next time.

Knix bras commercial
Asked by Joanne (1 year ago) Reply

Why does your commercial say I don’t have the time or patience for wire bras anymore ? It just doesn’t make sense
Silly comment in my option

Asked by Patricia Gibbs (1 year ago) Reply

As an MRI Technologist I am inquiring if there is any metal in the product, which can heat up during MRI exams and cause burns.

No exchanges!!!
Asked by Terri S Fisher (1 year ago) Reply

It would be awesome if you made it aware upon ordering that no refund or exchange was available when purchasing underwear! I realize that after going through the WHOLE website and reading ALL of the “questions asked ” that it is addressed but NOWHERE when ordering! I have $96 in underwear that I have to throw away!!! I love the product but they are just too small. Would live to exchange for larger size. Horrible business!!!!!

No exchanges!!!
Asked by Terri S Fisher (1 year ago) Reply

DO NOT ORDER unless you are absolutely sure of size! You can’t exchange or get refund on any underwear! NOWHERE upon ordering does it say this! I have $96 in underwear to throw away!😥

Asked by Debra L DeSanto (1 year ago) Reply

I cannot purchase any item made in China. What about the USA!!!

Underwear is not pee-proof
Asked by Kate Murray (12 months ago) Reply

I am sorely disappointed in this product. The underwear is not at all pee-proof. Avoid this brand and find another. Do not waste your money here.
