About Knixwear

Published on: Feb 6, 2018

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.

    I have five Knixwear bras. It took me a while to realize I was ordering a size too small as I am 34C and ordered a 4. Even with that, they are incredibly comfortable. I now have two size 6's and am loving them.

    Each time I've had a problem with a size they have immediately sent me a replacement and told me to keep the first one and give it to a women's shelter so it's not wasted. I have never wanted my money back as even when the size was off, they are so much more comfy than my expensive underwire bras.

    Their service is excellent. I am very impressed. I have been buying their bras and panties since they started and don't see myself changing to anyone else.

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

    I sent three email requesting them to address a price issue and never heard back from them. Bad customer service. To add more, at 180 words at least, I’ll say call call call back your customers. Stop hiding and post your phone number for people to call you.

  • Inaccurate sizing

    • Alberta, Canada,
    • Dec 7, 2018
    • Verified Reviewer

    I ordered the evolution bra. The material is very thin and flimsy, but it’s soft and does feel comfortable on. The issue is it fits MUCH too small. According to their size chart, I’m a 32DDD which puts me at a size 6.

    I can barely squish into the bra. When I’ve finally packed myself in, I’m left with spillage into my armpits, over the top of the bra and left with a weird uni-boob with nipples that show through a t-shirt because the material is so thin.

    They don’t do refunds, only exchanges. I’m really not keen at all to size up as I highly doubt one size up will fit any better, and after this experience, I don’t want to bother with the underwear or any other products.

    Very misleading and misrepresented, and sizes are completely off.

    Spend your money elsewhere!

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

  • Purchased bras and leak proof underwear

    • British Columbia, Canada,
    • Dec 7, 2018
    • Verified Reviewer

    Everything fit small.

    I had to put all of the bras on backwards, spin them around, and contort myself to get into the straps.

    I was spilling out of the sides of the Catalyst bra, and the straps were maxed out, so there is no way they would have crisscrossed on the back. The pads in the Padded 8-in-1 Evolution bras are insufficient for modesty and float inside the material like a cheap bikini top. The squished the top of my breasts and gave me a deformed uni-boob.

    The leak-proof panties were a monumental fail. Three styles leaked in about an hour on a light day. Do not use them as primary protection. Perhaps they would work as a backup for a Diva Cup?

    Consider getting a size larger for everything you buy.

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

  • Can't get money back, only store credit

    • California,
    • Dec 5, 2018
    • Verified Reviewer

    I thought I'd try out Knixwear's products so I bought a bra and panty and a tank. After I received the box, I saw that I couldn't return the panty even if I didn't try it on. That was annoying, but okay.

    I tried the bra and the tank and absolutely hate how they shape my body. It flattened my chest and squished it out the sides.

    I tried to do a return, but I can only get store credit.

    I don't want store credit - getting a different color isn't going to make me like their products! When I wrote to customer service, they reiterated I could only get store credit.

    What a waste of money!

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

    As of right now, I will not be shopping or recommending Knixwear to anyone due to the extreme lack of customer service! I have been trying since Black Friday to contact someone due to an error in my order. Not only have I not been able to talk to anyone, I have also missed out on the sale and am not even sure if I will be getting my order. I simply wanted to fix the error, the lack of customer service baffles me. Extremely frustrated and disappointed with Knixwear customer service.

  • Underwear now too small

    • Boise, ID,
    • Nov 29, 2018
    • Verified Reviewer

    I ordered 5 pairs of black large Knixteen underwear several months ago. They are amazing. When I went to reorder, I was sent similar, but definitely different underwear. The back of the old ones had an X, the back of the new ones have a KT instead. The new ones are much tighter. The new Large is too small for me, and I am a thin woman. I asked customer service but they never would answer why the new underwear is different. That is a ton of money in the trash, as they DO NOT refund or exchange underwear.

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

    You call this service?

    • Vancouver, British Columbia, Canada,

    First off, both phone numbers on their website DON'T WORK. I purchased a bra on October 24th. Just looking at it and measuring it against my other bra, I knew it would not fit. I went on their website to find out how to return it. Nothing, although it tells me to go to a certain page on their website. Then for some totally inexplicable reason, I received another perky little message from them stating that the bra I had just ordered would be arriving in the next few days. Huh?? I want to SEND back a bra, not purchase another that doesn’t fit! Next, I ordered a t-shirt and a top. I paid for these two items. So now, I’m stuck with a bra sitting here on my desk, another bra which I refused when the post person delivered it, and an order for over $120 which I have not received yet.

    What’s with this company? I just want either my money back for four items or money back for two items and the other two items delivered.

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

    Not for bigger cups

    • Florida,
    • Nov 3, 2018
    • Verified Reviewer

    I bought the evolution padded and unpadded bra in size 8 first and then 7. I'm a 38DD. At first, I loved them. Over time and use, they made my breasts look horrible. They both warped on the edges close to the armpits, which makes them stick out and the pads are also warped. I cannot use tight-fitting shirts because of this. My breasts also do not feel supported at all. A total waste of money.

    $85.00 and they don't even put it together you get to do that. I'm going back to Natori - less money and it's all put together. Plus it takes a long time to receive the item. Now I am asked to post at least 180 characters so I will say this is likely a company that won't last long.
