Knix Reviews

I bought five pairs of the period underwear less than a year ago, and despite washing cold/delicate and air drying them, in the last week they have started to fail, probably because they're GLUED at the seams, not stitched in any way. Two pairs have split from leg to waistband, which leads me to believe their lifespan is simply limited due to this defect. Annoying, but I was willing to give them a chance to fix it.

Then, when I talked to customer service about getting them replaced, they couldn't find my order and proceeded to get snarky and demanding about having the order number to do anything for me, culminating in this exchange:

Me: I've given you every possible bit of information I can. If your system purges guest orders I can't help that. Is there someone else I can speak to about this?

Guy from Chat: Our system retains all the information which is why I asked for all the information in the first place. I can ask one of my colleagues to look into this and get back to you in 24 hours

Nope! I told him to get stuffed and proceeded to message them on Facebook, of course, with no answer. And based on these other reviews, I'm not the only one.

It looks like that's just their standard business model.

I really hate wasting energy being this chapped about UNDERWEAR, but man, it's so frustrating to me to spend a bunch of extra money to try and make the most ethical purchase I can, only for this to go on. And it happens all the freakin' time with these greenwash-y companies. They clearly don't care that their panties are just going to end up in the landfill, despite waste reduction being their entire thing.

Length of Use: 6–12 months

They'll sell items with known issues, mark them as Final Sale, and use that as an excuse to not help you out for receiving a completely useless product. Understandably, Final Sale is just that, but that said you'd expect to receive an item that is usable.

Customer service is passive-aggressive and useless. Unbelievable how someone could work knowing they're ripping off customers.

Length of Use: 2+ years

Stupidly, I did not check reviews before buying from this company. I purchased three panties in size medium. I tried one on that was much too large. I gave that pair to someone it would fit and attempted a return of the other two. The site was uncooperative. The label they sent was useless because it would not print in a workable size. Customer service would not take my call, saying I would hear from them in 24 hours. Representatives were taking other calls.

Length of Use: Less than 3 months

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

All the money they spent on ads should have gone into actual experimentation and execution. These fancy panties are just a basic rip-off! The "leak-guard" panel is not even in the right place

So, do not waste your money, like I did! And especially do not waste your money on their "reusable" pads! What a joke!

I came upon a bra I bought from Knix last year. It sits in the bottom of my drawer because it is so shapeless and uncomfortable that I never wear it.

For me, it was expensive ($89). I had a Zoom session with a fit “expert” and bought 2 bras. I wear a 38/40 DDD. When I received the package, I followed the directions, washed it, wore it, washed it, wore it — it never loosened up.

Wearing it on the last hook I had nowhere to go. I had another Zoom with the “expert" and she agreed the Wing bra wasn’t for me but insisted the other one would loosen up and be perfect. It is not and never will be perfect. It gives me no shape — it flattens me out. I come out under my left arm and in the center. It is tight and uncomfortable.

I see the Knix commercials and every time I wonder why my bra doesn’t do all the things you promise. Washing it did not loosen it up or provide any shape at all.

I would be embarrassed to wear it. I will say the expert was great at convincing me to keep it because she wasn’t great at fitting me.

I contacted the company and because it was beyond the 30-day return policy, they offered me 15% off another bra. I was hoping for an exchange of a bra that would actually fit. I would NEVER buy a bra from Knix again.

Length of Use: 1–2 years

I had no problem with the fit or ordering experience.

I get Brazilian waxes once a month and have never had skin issues from it...until...I got these leakproof underwear! I wanted to use them to protect against bladder leaks and was anticipating getting the workout tights. They keep urine and sweat in for the most part, but caused such severe skin irritation due to the constant contact with my skin during the day that I had to stop wearing them. As Kathi B said below: the claims are untrue, and I could smell the odor of urine taking off my pants.

I see nothing else about this from other users. Glad I only purchased one pair to see how it went.

Run away! Do not buy anything from this company. I bought the best-rated undies they had for heavy night flow. Paid $200 plus. Failed miserably! Went straight through. I have pictures. Tried to get a refund, tried to work with customer service. Never responded. THEY LIED!

I'm so disappointed...I cannot wear the bras I bought anymore. They have completely lost their shape and are too loose. I washed them in the super delicate cycle in cold water and hung them to dry. I bought one last August and two more last winter. I'm used to bras lasting at least a year. At the price I paid for the bras I cannot afford to replace them every six months. It's unfortunate because they are so comfortable.

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

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

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

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!

I bought 2 pairs of essential highrise seamless underwear online and was very disappointed with the fit. I am size 4, so followed your guideline and got size Small underwear. The underwear rides up, seams can be seen through clothing and they are very uncomfortable! At $50 to have 2 pairs shipped I was extremely disappointed and would not buy this product again.

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

I purchased 2 pairs of Knixwear Thigh Savers. Following the size guidelines, I ordered the XXL. Each individual item comes in its own sealed package. I tried on one pair but found it to be extremely big. I immediately contacted the company but was informed that they will not accept return on the UNOPENED Thigh Saver. They told me that they couldn't be sure that I hadn't opened it. Shortly after, I went to their Toronto showroom for a fitting, taking the UNOPENED Thigh Saver. Again, I was told that even though they could see that the package hadn't been opened their policy does not allow returns on Thigh Savers. UNBELIEVABLE. By the way, I was fitted with the Large size and they constantly fall down. I am very disappointed and will not buy anything else from them. BUYER BEWARE. Having said all of this, I have to say that the staff was very nice and helpful.

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

Comfort is great and I was so excited. Unfortunately, I got only 3 wears out of 2 of them, and my 3rd pair fell apart (came unglued) after the first wear.

So unless you can afford disposable underwear, keep looking.

I was very excited to get the Knix maternity leak-proof bra, however, I was very disappointed. First of all, it was not leak-proof, which I was expecting but still misleading. Second, it was too small, even though I was average on the sizing chart for the size 7. Finally, the cups inside the bra are not sewn in which makes them fold constantly and is super uncomfortable and unhealthy when you’re breastfeeding. Who has time with a newborn (or twins in my case) to sew a bra? I finally got so fed up I ripped a hole in both cups to remove the cup and unfold it. Overall not a good experience.

Length of Use: 3–6 months

Bought 3 pairs of boyshort regular underwear, size M, and was so disappointed that the waistband continually rolls and won't lay flat. I kept flattening the waistband all day. The material and wear were fine, but the rolling waistband was so annoying I can't wear them.

Not a good design for overweight women, which is ironic given that most of the models shown on the website are heavyset. That was one of the alluring things of the website, that they use regular size women with stretch marks, like many of us. But the boyshorts don't sit well during wearing.

I actually bleed outside of the liner area... it's like whoever designed this only bled straight down, or was not a woman at all. When you are sitting, walking, doing exercise, sleeping, your body movements change, and so will the blood exiting. I'm sitting often, so the blood pools, just above where they put the absorbent liner area. It's very frustrating, I have to put in a liner on top of the period panties so my period doesn't miss the mark.

They are okay for sleeping, but that's pretty much it. I wouldn't wear this outside for any reason.

Length of Use: 6–12 months

I bought leakproof underwear about 6 months ago, so it only has 6 wears and it’s already ripping at the seams. I’ve bought much cheaper underwear that’s lasted much longer. I don’t even put these in the dryer so I don’t know why it’s ripping. Plus, the absorbency is not that great and I got the ones that were supposed to be for heavy flows. I can only wear them on my light days or else I’ll bleed through. Thinx is much better.

I bought a bundle with a bunch of different types and loved them at first. My period is very heavy so I liked them as backup paired with a pad or Tampon for extra protection.

I've always made sure to wash them based on their instructions and they now do not fit properly. Beyond that, the absorbency is not as good as it originally was.

I would also like to add that the absorption part should be higher and further back.

Length of Use: 1–2 years

Ordered 4 Medium boy shorts. Huge in the leg, rendering protection useless. Wear a Medium in every other brand. More like a hipster than a boy short. Too much money wasted. Can't get anyone in customer service to do a return. Can't write a review. Can't even access my account.

I'll be honest. I'm a FAT woman. Periods are difficult for me because pads bunch up and then rip off while pulling down my underwear, so you can imagine what fun that is. I also have HEAVY periods. I used to swear by tampons but because I'm so fat now, they are extremely difficult for me to insert. I was so excited to find an alternative to bulky, bunchy sticky, messy pads and impossible for fat-me to insert tampons.

I bought some Knix overnight dreamshorts. At first, I LOVED them. They were SO comfortable. "Is this real life?", I thought. Periods weren't supposed to be comfortable. These were great! Sure, not one night would go by that I wouldn't leak out the back, side, or front — but that's something I was used to.

Now comes the fun part. The instructions say they can be just thrown into the washer. Hell, they say they can be put into the dryer too! What a dream! Well, that's all it was. I wash them and dry them. Take them out of the dryer and they STINK. Like I just opened up the 2-week-old garbage can and took a big whiff. I decided, "ok, I will now handwash them and THEN throw them into the washer and hang them to dry". That solved the smell issue. But nowhere as easy as they made it out to be.

Second issue: After about 3–4 wears, the seam right in the butt would rip. I've thrown out 4 pairs as of now that ripped right down this seam. I know I'm large, but come on. The seams are GLUED. So the glue eventually wears down, and tada! Anyone for a bloody full moon?

All in all, I love this idea. I just wish they were better quality, as these ones really suck.

I love the bras. They are sooooo comfortable. BUT, there is one problem that nobody seems to talk about, and that is between the breast perspiration. I am not a big "sweat'er," however, these bras are not made for summer wear.

You don't have to be exercising to experience this problem; the weather just has to be warm. It is very uncomfortable and can cause a rash and be VERY itchy. I even tried deodorant; yes, on, under, and between my breasts. It helped a bit but not enough.

I contacted the company and they did not seem surprised nor did they have a "fix." Unfortunately, this is a deal-breaker for me.

But I am amazed that none of the reviews I read on their site talked about this issue.

I purchased the 8 in 1 sports bra in a size 5 as suggested by the company sizing chart. The product shipped super quick and got here within 2-3 business days. I had to add an adjuster on the band, not a big deal, but the cup was small. I filled in to exchange it for a size up (6), and a message popped up to say there was no need to return the last one and to donate it or give to a friend.

Again I got it in a couple of days, this time the cups fit but the band did not. I contacted Knix and the woman who responded to me explained the sizes are not sequential, therefore a 6 is smaller than a 5 in the band. She said a 7 had larger cups but had a band 1.5” shorter than the 5 and an 8 had the same size cups as the 7, but a larger band. So again, I put in an exchange request, this time for an 8 as suggested to me, and I was told to donate the size 6.

I received the new one in 3 business days. The band is perfect, but the cup is just a smidge too big. Other than a 7, I have no other size option...so I will keep the 8.

All in all, pretty disappointed in their size range. The chart is very inaccurate, and for ease of order, the sizes SHOULD be sequential. The bra itself is soft and supportive, but the band rolls up. Before ordering I would highly suggest you do ACTUAL measurements before ordering and not just go by your current bra size as the chart doesn’t seem to match up. I received it quick, good customer service. I would say it would be a good experience for someone with a smaller build so the band won’t roll, but overall I would not recommend given the inconvenience of back and forth sizing and inaccurate size charting.

Order was very fast. The panties are so comfy.

However, I have incontinence big time. I wear disposable pads every day. They are overpriced, but I thought in long run it would pay off to not buy disposable pads. They don't work for heavy incontinence. I am still buying pads. I bought 7 pairs. I will try the bra when these are paid off. I hope they are comfy as panties.

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.

I purchased 4 pairs of leakproof underwear prior to my most recent period and I was very happy overall with how well they work! The super leakproof high-rise are my favorite, as I stayed comfortable and dry throughout the night, with no leaks onto my sheets. The leakproof cheeky work perfectly for medium to lighter days. After a few wears, they fit perfectly and do not create noticeable panty lines under leggings.

The one disappointment I had was with the heavy leakproof thong. The absorbent material is mostly in front/above where it needs to be, leaving only a small section of absorbent material where you need it! Within an hour of wearing it, the thong leaked out the back, over the side, and stained my pants.

Besides the thong, the other pairs kept me dry and stain-free, and they are easy to wash and dry. I will definitely be ordering more pairs, just not of the thong!
