About Knixwear

Knixwear advertises that by making the most comfortable wireless bras and seamless underwear available, they’re reinventing intimates for real life.

Specifically, the website tells us their garments utilize four-way stretch fabrics to mold to your shape, move with your body, and deliver comfort, in addition to moisture-wicking, anti-odor, and quick-dry performance so you can “conquer your day.”

Knixwear certainly seems to offer real intimates for real women, but does that necessarily mean that they’re right for you? What about their tanks, tees, loungewear, and accessories?

Buying underwear and bras is already frustrating enough. Here, we’ll help you make your purchasing process easier by providing the details you need to make an informed decision about Knixwear—starting with what they offer.

Knixwear’s Underwear Line

Dubbed “the world’s most comfortable underwear” by the company, each pair features seamless construction, a bonded technology that gets rid of bulky stitching, and the ability to avoid bunching, pinching, and rolling.

In fact, the company claims that their underwear is so seamless “that it has become a staple in the equestrian community — it’s invisible even under those super tight, white riding pants.”

Leakproof Underwear

Knixwear tells us that CEO Joanna experienced frequent stress caused by postpartum leaking, which is what inspired her to create the brand in the first place.

Made from top-of-the-line Italian textiles, their Leakproof line of underwear features a barely-there, built-in panty liner that promises to absorb 1-3 tsp of liquid (1-2 regular tampons worth), without a lot of bulk. They also feature a quick dry, moisture wicking gusset that’s said to dry two to three times faster than regular cotton, as well as carbon cotton to fight odor, across seven styles:

  • Athletic – A mid-rise option that provides medium coverage for the hip and rear end. Compared to the Everyday line, all Knixwear Athletic styles feature stretch tech fabric that will relax a bit more.
  • Athletic Leakproof Boyshort – Additional coverage in the hip and rear, and sit slightly higher than a Bikini.
  • Athletic Leakproof Thong – Another mid-rise option, but one that delivers minimal coverage in the rear.
  • Everyday Leakproof Bikini – The Everyday line hugs more than the Athletic line, and the Bikini style delivers medium coverage on the hip and rear.
  • Everyday Leakproof Boyshort – Extra coverage through the hip and rear, and sit slightly higher than Bikini.
  • Everyday Leakproof Highrise – Sits at your natural waist and offers medium coverage (similar to Bikini) in the rear.
  • Everyday Performance Bikini – Mid-rise and medium hip and rear coverage.

Athletic Underwear

Seamless, moisture-wicking performance underwear with stretch tech that’s designed to “maximize movement and comfort during your most intense workouts.” From a fit perspective, according to the Knixwear website, these will relax more than the Everyday line.

Each pair also comes with bonded construction for invisible panty lines, a quick dry gusset with carbon cotton for odor-fighting protection, and super-soft fabric. Styles include:

  • Bikini – Mid-rise and medium coverage through the hip and rear.
  • Boyshort - Extra coverage through the hip and rear. These sit a little higher than Bikini.
  • Thong – Also mid-rise, but with minimal coverage.
  • Cheeky – Light rear coverage and the lowest rise available.

Everyday Performance Underwear

Knixwear tells us that this line features “light-as-air fabric and give you that naked-but-better feel, while soft velvet flocking hug your curves.” The seamless, bonded construction means they’re invisible under clothes, and the line hugs more snugly than Athletic:

  • Bikini – Medium coverage and a mid-rise silhouette.
  • Boyshort – Extra coverage in the hip and rear with a slightly higher sit.
  • High Rise – Medium coverage in the rear, and sit at the waist.
  • Thong – Minimal coverage and a mid-rise silhouette.

Luxe Essentials Underwear

This Knixwear line boasts a super soft, moisture-wicking fabric, a comfortable velvety waistband, and mesh paneling down the side for comfortable sexiness. Sits at the natural waistline and provides medium rear end coverage.

Thigh Saver Essentials

Long leg underwear with the same seamless design, built-in gusset, moisture-wicking fabric, and thoughtful design to help avoid chafing as many other styles in the Knixwear lineup. Ideal for wearing under your favorite summer dress.

Knixwear Bras

All of Knixwear’s bras are underwire-free, provide support from an A to an E cup, and are said to feature “comfortable performance fabrics that evolve with your day.”

V-Neck Evolution Bra (Standard & Luxe)

Seamless, molded construction, thicker straps for extra support (straight or cross-back), and a v-neck silhouette that can hide under any top. Unlined and unpadded, so it molds to your natural shape.

The Luxe V-Neck version adds velvety detailing on the straps.

8-In-1 Evolution Bra (Padded & Unpadded)

Features reversible colors and two sets of detachable straps, allowing this bra to deliver eight different wearing options.

Knixwear also offers this in a padded version that features ultra-thin, reversible, breathable cups for “an extra layer of modesty, without volume.”

Longevity Bra

A medium-impact sports bra that Knixwear says can be worn on its own, or under any other workout gear. Features a long-line cut and a form-fitting, reinforced underbust for extra lift and support, moisture-wicking performance fabric, and unique back detailing. The cups will provide some measure of compression.

Knixwear Tanks & Tees

Evolution Tank

This pullover style tank is designed to act as a sleek base layer. It comes with a built-in bra that’s bonded and wire-free, with thin, removable cups to add shape and coverage without bulk, along with a secure, comfortable fit.

Fits up to a DD cup and can be worn on its own, or invisible under whatever else you choose.

Don’t Sweat It T-Shirt

A garment that uses Knixwear’s Fresh Fix Technology in the underarm panels to help block sweat, absorb moisture, and eliminate odor. The fitted silhouette helps maintain comfort and allows you to wear the garment under clothing, while the four-way stretch design won’t make you feel restricted.

Knixwear’s Knixteen Line

According to the website, Knixwear’s teen line features the same leak-fighting and period protection as their standard underwear line, including a seamless design, super soft Lycra Sports fabric, carbon cotton for odor elimination, and ‘Oh-No’ Proof Technology that uses a thin built-in panty liner to absorb up to 1-3 tsp of moisture (1-2 tampons worth).

These also feature moisture lock sides to keep leaks in, are lightweight and fashionable, and are easy to clean, so the company emphasizes they’re ideal for anywhere.

The biggest difference is that Knixteen styles boast “a different size set and silhouettes to match a growing body.” Available in Boyshort and Bikini styles.

How Much Do Knixwear Products Cost & Where Can You Buy?

Individually, Knixwear’s intimates are priced at:

  • Bras: $45 - $60
  • Underwear & Shorts: $20 - $38
  • Knixteen: $17
  • Tanks & Tees: $48 - $65
  • Loungewear & Accessories: $10 - $69

However, in many instances, you can save by bundling items or building complete sets. At $18/mo, the company’s Club Knixwear subscription program also delivers a new pair of underwear to your door once per month and allows you to skip a delivery or unsubscribe at any time.

Online US orders are charged a flat $8 S&H fee, while Canadian orders will be charged $10, plus tax.

In addition to directly through the manufacturer’s site, Knixwear’s intimates are sold through Amazon and TheGrommet.com, as well as dozens of in-store retailers throughout the US and Canada.

Money saving tip: If you’re an Amazon Prime customer, this could potentially help you save money on S&H charges.

Clothing (Bras, Loungewear, and Tanks) comes with a 30-day refund policy, less S&H charges, although according to the company's FAQ, they'll need to be unworn, with the tags still attached.

Underwear, whether worn or unworn, are not eligible for refunds or exchanges for hygienic reasons. Accessories are not eligible for refunds.

Customer support can be reached at info@knixwear.com.

What Can We Learn From Knixwear Online Customer Reviews?

On Amazon, Knixwear’s Moisture Wicking underwear had more than 30 combined reviews and an average rating of about four stars. Common compliments related to comfort and the soft, seamless fabric, while complaints frequently referenced less-than-stellar comfort or fit, and inaccurate sizing.

On TheGrommet.com, Knixwear’s Reversible 8-in-1 Bra had a total of 110 reviews and a 3.2-star average rating, with many of the same compliments and complaints.

Lingerie Detective provided an in-depth review regarding their experience with the Evolution Bra, and noted that they were pretty happy with it, overall. They liked that it centered their breasts, held them securely in place (even without an underwire) and lifted them away from their body, without causing any tissue folding. They also emphasized that the band and straps were super comfortable.

However, she pointed out that since the bra features two sewn loops at the strap, it’s technically not 100 percent seamless. Regardless, she recommended it as a great bra for everyday wear, including low-impact sports, sleeping in, and hanging around the house.

As a company, Toronto-based Knixwear launched their Evolution Bra via a 2015 Kickstarter campaign, where it on to raise more than $1.1 million—followed by an Indiegogo campaign that raised another $1.6 million.

The company was founded in 2012 by CEO Joanna Griffiths, who previously worked as Director of Business Development for Bre.ad (acquired by Yahoo!), Promotions Manager for CBC Television, and Media Relations Manager for the Toronto International Film Festival.

Knixwear held a B rating with the Better Business Bureau, as of 2/1/18, although their main page with reviews and complaint details wasn’t available during our research.

How Does Knixwear Compare to Other Intimates Companies Like Thinx, True and Co, and Thirdlove?

Did we encounter any seamless intimates company that offered an identical lineup of bras, panties, and other garments and accessories to Knixwear? No. However, this doesn’t mean they’re your only option when it comes to individual designs.

For example, Thinx’s line consists solely of anti-microbial, moisture-wicking, absorbent, and leak-resistant ‘period panties,’ although they offer a greater variety of styles, including hiphugger, hi-waist, and sport, in addition to some styles with cotton fabric.

Price-wise, Thinx’s lineup falls between $24 and $30 per pair, putting them relatively on par with Knixwear’s offerings. However, Thinx also offers a 60-day refund policy.

True and Co offers bras and panties like Knixwear, although in a much greater variety of designs, styles, and materials (no leakproof options), including their True Body seamless collection. Prices range between $44 and $64 for bras, and $16-$32 for undies.

Differentiating themselves, though, True and Co also sells lingerie and men’s underwear.

Like Knixwear, Thirdlove sells their own line of bras (t-shirt, full coverage, racerback, plunge, strapless, etc.), underwear (thongs, bikinis, and cheekies), and loungewear. However, like True and Co, Thirdlove also offers a greater number of styles and materials.

Prices typically fall at the upper end of the spectrum compared to the above competitors, with bras typically between $68 and $76, and between $12 and $15 for each pair of underwear (or, three for $27 in many instances). Thirdlove’s unique Try Before You Buy program also allows you to return their intimates if they don’t meet your needs, even after being worn.

How can you choose which of these options will best meet your needs, before handing over your hard-earned money? Let’s carry this thought over to the final section as we wrap things up.

Our Final Thoughts About Knixwear

We didn’t try any of the Knixwear lineups ourselves, but based on what we learned during our research and from online reviews, they seem to feature a unique seamless design that’s comfortable for most consumers, a broad range of styles, competitive pricing, and a 30-day refund policy.

However, unlike close competitors True and Co and Thirdlove, Knixwear doesn’t allow returns on underwear that’s been worn or had the tags removed. In reality, this means that as soon as you try their underwear, you own it.

  • Frustrated at first

    • Edmonton, Canada,
    • Oct 15, 2018
    • Verified Reviewer

    I bought the evolution non-padded bra from a neighbor who ordered the wrong size for herself, and the size would fit me according to the Knix website. At first, I was very frustrated as the bra was too tight and their sizing system made me very angry. I stuck it out, and by the third time I wore it, the bra molded to my shape (even with washing it between each wearing), and I am now happy with the bra and fit. No issues, very comfortable. I do not find materials cheap like some of the other reviewers; I think it is a very good quality material. I am overall very happy with Knix Evolution...although I am not throwing out all my other bras as there are many other quality bras out there that I love, and Knix is only one of them.

    Bottom Line: Yes, I would recommend this to a friend

    I ordered the Evolution bra and I love it. I am plus sized and hate underwires. I find this bra very comfortable, and it stands up to repeated washing. I just ordered three more.

  • Promising but not for larger women

    • Ottawa, Ontario, Canada,
    • Oct 3, 2018
    • Verified Reviewer

    I love everything about the bras...amazing fabric, seamless, the potential to be super comfortable. Sadly for larger women, even the 8 and 8+ sizes they offer aren’t suitable. My other bras are 40DDD, which should fit based on their sizing guide. The Knix bras also moosh into a mono-boob and cause flesh-bunching on the back and under the arms.

    I had very high hopes for this bra, as most conventional underwire bras (even professionally fitted ones) cause pressure points and, when the wire pokes out of the fabric, OUCH! They aren’t for long-term wear. Hopefully, with feedback and a bit more hands-on research with larger women, Knix can bring relief to the single most critical market for bras - larger women with larger breasts.

    It’s all there, it just needs fine tuning.

    Bottom Line: No, I would not recommend this to a friend

  • Sweat-proof t-shirt

    • Toronto, Ontario, Canada,
    • Sep 13, 2018
    • Verified Reviewer

    I ordered this a few months ago and it took a while to come as they oversold. That wasn't a big deal for me. I have used it many times now, and my biggest complaint is that the neckline is too high so you can see it under my dresses at the front and the back. I don't like that look. Also, it traps odor and doesn't wash away. I know it's meant to trap sweat, but I find it gives me a strong smell of BO that I didn't have before. The fact that it doesn't wash away is a problem. I recommended this to two friends who also noted this problem. I have stopped wearing this t-shirt as I would rather wear black and mask the sweat spots than smell really bad!

    Bottom Line: No, I would not recommend this to a friend

    Don't waste your time or money

    • Arizona,
    • Aug 26, 2018
    • Verified Reviewer

    I ordered a bra in my size, and it would not even come close to going around my body. I called in and they said to keep it (for what?), and they would send next size up. That came, and with an extender could squeeze into it, but the front bulged out, even those this next size up was a double D cup and I am a C, which was not the problem in the first place.

    I now own two useless bras that I can probably use to hang bird feeders from?

  • I love their thigh savers and bra

    • Toronto, Ontario, Canada,
    • Aug 22, 2018
    • Verified Reviewer

    I actually love Knixwear despite all the negative reviews on here. Their thigh savers have been amazing under my dresses in the summer. The bra I purchased is just as awesome! I would say to order a size up in bras if you fall in the middle of two sizes though. I get it can be frustrating when it comes to returns, but it does state on the website.

    Love turned to disappointment and lachrymose

    • Wilton, CT,
    • Aug 18, 2018
    • Verified Reviewer

    I at first I was so thrilled with my 6 new Knixwear bras! From the packaging to the soft material. I invested almost $300 in what I was sure was my long-awaited, comfortable, long lasting bra collection.

    But sad to report that after only 3 months of wear, I only enjoy wearing 1 sole bra - the Longevity bra, but only in blue.

    The Longevity bra in grey - the material is non-breathable and contributed to my developing a fungal rash in my cleavage from sitting sweat.

    The "Evolution" padded bras - not only did the pads inside float and warp, they are now too loose to provide any comfort let alone support.

    The Racerback bra had the same issues as the Evolution bra.

    I wrote to Knix and included photos highlighting all of the rapid decline. They at first wanted to resize me. But I had already been through 3 sizes, so I requested a refund.

    They refunded me for 2 of 6 - better than nothing. A big waste of excitement, time, and money.

    Bottom Line: No, I would not recommend this to a friend

    No returns accepted

    • Sarasota, FL,
    • Aug 12, 2018
    • Verified Reviewer

    I ordered two bras and both offered insufficient support for a big bust. When I attempted to return them via the online return system, I was not allowed to request a refund, only a credit. This is not what I read when I ordered these bras or I would not have placed the order. There is no human you can talk to, no phone number, no response to a message on facebook. Sham or not? I say SHAM!

    Bottom Line: No, I would not recommend this to a friend

    Promised return, would not honor

    • Chicago, IL,
    • Aug 11, 2018
    • Verified Reviewer

    I tried a Knixwear bra for the first time online. Size 5 was too big around the ribs so I exchanged for Size 4. It was too small in the front. I wanted to return but they would only give site credit, not a refund. I would not have tried the bra without a return guarantee as I did not know how it fit. Bait and switch.

    Bottom Line: No, I would not recommend this to a friend

    Impossible to get a decent fit, and impossible to get refund

    • La Quinta, CA,
    • Aug 11, 2018
    • Verified Reviewer

    I ordered three tops and based on my size, I should wear a Small. I'm 5'3" 110 pounds. They were so tight, they hurt.

    I tried for a refund, but no, I could only do an exchange. Okay, I'll try different products and go for a size medium. A couple of the items seem to fit, and I will be able to use them, but they aren't particularly comfortable...but not unusable either. But one item, which was on clearance, was so large that I could be six feet tall and it would still be too long in the trunk. The sizing of this item is in the extreme, the opposite of all the other items. It too is a Medium, but I probably need an Extra Small. Of course, since it was on sale, it's not refundable, and it doesn't even qualify for an exchange. So, I have this thing that is not sized in relation to any of their other products, and I can't exchange it, and it's like throwing money away.

    The products themselves are quite cheap and not very comfortable. The prices seem way out of line with the quality. I gave them two chances and tried a variety of their products in the process. Save your money. These products are sized randomly, and impossible to get a good fit without several tries. And if you happen to take advantage of a price reduction take a match to your money, it will save you time and effort.

    Bottom Line: No, I would not recommend this to a friend

    Not worth the hype

    • Denver, CO,
    • Aug 7, 2018
    • Verified Reviewer

    I got a 15% off coupon that wasn’t taking 15% off. I contacted them to find out not all items qualify for the 15% off order. I personally think that when companies do this, they are jerks. Then I ordered the three mystery pairs of undies and I got three slate green. OK, so when they offer that deal, they have a color they want to get rid of, and you are just going to get one color.

    Then I put them on. I thought, oh, these fit nice. Not pinching anywhere, feel really smooth and flat against the skin. I went to put my pants on, and they rolled down. So on top of them just not giving a crap about the consumer, their product is not that great for what you pay.

    Bottom Line: No, I would not recommend this to a friend
