Knix reviews and discussion

I tried one of their sports bras that was advertised as being a good fit for DD+ cups. It was not. It felt like I wasn't wearing a bra at all, and not in a good way. There was no support whatsoever, making it impossible to do anything active. The saving grace is that the return and refund process was super easy.

I have purchased both bras and leak proof undies from this site. I would give the bras a 2, but the undies a 5. I found the wireless bra 3 pack I ordered, which included 1 strapless, to be very uncomfortable. The underwear thought I ordered a 3 pack loved them and ordered more. My favorite is the cotton leak proof. It holds considerable amounts of liquid without leaving any odor. I will definitely be ordering more of the undies.

I've been buying knix underwear for years now. I love their essential undies and they are the only ones I buy currently. They are seamless, great for exercising and come in a variety of cute colours and patterns. They are not cheap, but you can often bundle them or find sales that make them slightly more affordable. They also hold up way longer than any other underwear brand I've bought before. I own a couple of their bras as well, the pullover bra and the essential bra. I am small chested and unfortunately have found the other options do not fit me well. The quality of the fabrics though is up there with their underwear!

I bought two pairs of period underwear from Knix but I also tried different brands. Something is missing in the quality when compared to other period underwear brands. They're quite hard to wash and the fitting is too tight in the belly area which makes me uncomfortable when I'm on my period. I choose to wear them on lighter days.

I like Knix's brand of period underwear. I have three pairs that I use as backup when using a menstrual disc or on my lighter days. Comfortable to wear and comes in cute colors!

LOVE the high-waisted thong. It's like all I can wear now. I've transitioned to leakproof underwear and no longer use tampons (very very rarely) for my health and the health of the planet, and I love that Knix tests their materials for PFAs (forever plastics). The ongoing lawsuit is a bit worrisome, but for now I trust their transparency.

Great alternative to thinx. Looks cute and fits well, works just fine.

I ordered a few different styles of undies during their Black Friday sale, and while the fabric seems nice and high quality, the sizing is way off. I am usually small/medium (6/8) depending on where I shop, so I ordered a medium to be safe and they are so tight on me. I’m just really confused on their sizing. The bikini panties and things are Not very flattering or comfortable to wear unless I’m in jeans that can hide how tight they are on my skin. Really bummed about this one.

I love this brand. They make up my entire closet of undergarments.

Leakproof underwear has become a game changer for me, and I feel super secure wearing Knix’, especially their high waisted underwear. Their loungewear is also great. I once bought a good to go cropped crew neck that I loved so much that I bought it in two additional colours! My current favourite products are their cotton modal high rise everyday underwear. However, they very rarely update the colours; and never have the same fun designs they have in their leakproof or everyday underwear, which is disappointing. Their products are expensive, so I normally wait for sales. While their underwear size range is decent; their bra and apparel size range is not, which sucks.

I purchased a full week package in black as my first foray into period underwear and was very impressed! They are comfortable, well made and I frequently forget I am wearing period underwear. I've since tried other companies version of period underwear and they've been too padded and tight around the leg holes. Knix gets it right!!

I own a 3 pack of the leak proof briefs. They fit true to size, definitely do not leak, and are comfortable. They are a game changer.

Great fit and fun colors! I do however wish the absorbent material went higher up in the front and back of their bikini as it just doesn't have enough coverage for me. Despite this, I do wear the leakproof bikini just around the start and end of my period just in case and it works quite well. I also own the Catalyst Sports Bra in black and quite like it! It does ride up a bit and cause some spill over on the sides but I think that's just because I have a weird bra size (32H) that is hard to find a fit for. I think the sports bra would work much better for those with a medium cup size.

I have both period underwear and thongs. These are amazing! I’ve saved so much money on pantyliners, tampons, and pads since buying Knix underwear. They’re extremely comfortable. I even like wearing them when I’m not on my period. They’re absorbent but not messy at all. I’ve never noticed an odor after using them, super easy to clean. Great quality product. They now make more than just underwear. They have swimwear and athletic wear. This brand is very inclusive and has a variety of products and sizes to fit any body.

I'm so grateful to have found Knix. Their period underwear is so comfortable, seamless, not bulky and works great. I haven't had to buy any pantyliners anymore. Their swimsuits are also super cute and flattering. I love all the prints they have for their products!

these underwear are perfect for when i just want to feel like im free-bleeding without making a mess. they wok so well for sleeping in and i love how comfortable they are

I always recommend Knix period underwear to friends so that they can have a zero-waste period. I have their super absorbent and medium absorbent underwear and they help get me through my period.

I like that they are somewhat size inclusive but found the products didn’t work well for me. Products break down in the wash, and seams separate. I have a large chest, and have a hard time finding a bra. I got a few from Knix and after some sizing back and forth found my size. They were amazing about returns. I found the bras somewhat comfortable but still wanted to take it off by the end of the day. I found them to become less supportive over time, and still dig in in certain places. The straps also can pop off due to strap design. The material of the underwear feels nice but doesn’t breath well.

I really like these for underwear to use on my period. I have it in black and they're really comfy and effective.

I was pleasantly surprised by the underwear I purchased from Knix. I bought them from KT (their teen line), but I think the quality is the same as long as you size up a bit. They're a good replacement for pads, but I would be mindful of their capacity. Also, they're not reusable since you should wash them right away- it's a bit impressive/scary how much blood they hold.
