Every product I have bought from Knix has either leaked far too easily on me or was a very poor fit. However, they are constructed well. Are absolutely not my go to for period panties. 

Such a fan of Knix bras! These bras are wireless, which is sooo good for your overall breast health and it makes them super light and comfortable to wear. Holds up the girls really well, with excellent supporting straps that are adjustable on some styles! Feels like I have nothing on throughout the day when I wear these! 

I am a big fan of Knix. Their products are high quality and I prefer their period underwear to all others I’ve tried. The two potential improvements are that 1) sizing can be different between items and 2) over time the “linerless lining” eventually seems to peel off. However, that is just being nit-picky, because I truly love their underwear. The dream short is a winner! 

Just got a whole set of their period underwear. They're comfy and do what they were advertised to do, I'm a fan!

Less bulky boyshort period panties and better, higher quality leggings.

I love these panties. I have both regular and period ones. I don’t love the boy short period panties because they’re a little bulky. I prefer the Thinx version. Still, all around, great underwear that is really comfortable. Was not impressed with their leggings.

Smaller band sizes and larger cup sizes for bras!

These are my go to daily underwear and period underwear. Pretty good quality, there period underwear holds a good amount of liquid. 

Great company! They have the best customer service!!! I am large breasted so I find it hard to order bras online. Unfortunately I took one star away as I couldn’t find the perfect fit in the bra I was purchasing. It was either too big or too small. I will definitely try other styles as they may fit differently. Fast shipping too! I received my package within 2 days

Bra: I wanted to love these bras. I got fitted in store, the quality is really good, however they always feel like they are riding up.
My friends swear by them. I am very petite, I think they may be more geared for regular sized/large breasted folks.
Period panties: incredible. Love love love them . Totally worth it

I have tried a couple of different period panties but I love Knix's cotton line the most! They are comfy and not too bulky and easy to clean. Love the size inclusivity and they have core and fun colors.

I've also tried one of the cotton pairs. They fitted a little smaller so I would say size up. The cotton pair is also lovely and soft, but ultimately I didn't like them as much as the seamless pair b/c of the VPL.

High five to Knix on the leakproof seamless underwear! Buttery soft, feels like a warm hug around my butt when I wear these, which is what I want during that time of the month. These have 0 VPLs and fit perfectly. Sometimes, I find with seamless stuff that the adhesive along the seams wears away after a few washes and the seams come apart... but not these! 1.5 years in and they still look new. 

Knix is the one and only period underwear you need. No flashy ads, basic ass packaging and they're Canadian. They don't need to use gimmicks to sell you on their product, it's just that good. No complaints.

Make it so you don't have to spend a fortune every couple months. 

Undies stretch out after a couple months. 

Its a good basic for any menstruating person.

I have several version in different fabrics and for different flow levels. They are comfortable and have so far been very reliable for menstrual care. I feel like the sizes run a little small, and (of course) they don't feel very breathable, so I definitely don't like to wear them the rest of the month. But it feels really nice to not worry about leaks and ruining clothing each month.

I love this brand. I own a handful of their styles of period underwear (bikini, thong, and dream short). They both serve their purpose and feel like nice underwear — lots of aesthetically pleasing colors & patterns. I know everyone's period is different, but I love the dream short in particular so that I don't have to sleep with a tampon in or pad. 

It's a bit annoying to work into your life. I like to wash it within 24-48 hours of wearing it, but it is a bit of work - during the time I'm not very productive. It's definitely not as easy as the disposable stuff, but happy to be doing good for the earth. 

I got the bike shorts. I love that they have pockets and look like regular shorts. Next time, I would probably try just the underwear to change my look during that time of the month. I got black so they were easy to clean in the wash. I have a heavy flow and usually would get leaks, but happy to report that this works really well! 

The leak proof nursing bra is 1000% worth it. Buy this as a gift or buy a gift card for a maternity gift! 

I bought five pairs to wear after my baby was born for PP bleeding. I really like the fit but the liners do not disperse the blood well and the crotch is super narrow. I also am disappointed to hear they contain PFAs. The leakproof nursing bra is pretty genius, but the fit is weird. I love my biker shorts, but they do run small.

If I had read the reviews before I made my purchase I wouldn’t be writing this now I paid to much for a bra that DO NOT serve it’s Purpose and when I contacted Customer Service they did’n response back 

Their products are pretty good, especially the quality, which is above average. The only issue I found is that they don't fit like their photos. Fortunately , they have multiple models, and more or less, I can get an idea, but still, there are some big differences I dislike. I'm satisfied except for this little caveat 

Love their period underwear and the fact that they come in different styles and absorbencies. Nice to have as backup on heavier days or to wear alone on light days.
