So, I guess I’m breaking a vow to write this Knix Underwear review, but I promise it’ll be worth the read.
When I started my blog a little more than 6 years ago, I vowed I would never write about periods. I just wanted to focus on the fun things in life, and periods are always a buzzkill.
I don’t even have to elaborate. We’ve all gotten our period during a beach vacation or special event, and it’s less-than-awesome.
But, one of the goals of this site is to give families life hacks that make life with kids easier and stress-free (well, as stress-free as we can make it!)
One of my blogger friends, Julie Bigboy from Mom Rewritten, posted something on Facebook about doing research for period underwear reviews, and she had just tried Knix leakproof underwear.
I’ve been curious about period undies for several years, but I wasn’t sure if they were worth the price or not. I’m a total discount shopper and try to avoid paying full price for things if possible.
So, I started reading online reviews and Facebook comments to see which brand I should try. I saw a few comments about other brands’ products having chemicals, so I decided to try Knix period underwear.
I bought a couple of pairs just to try out for myself, and then I immediately bought more in the styles I like.
Because it’s been such a game-changer for me, I figured I probably should write this Knix period underwear review in case other women are curious. This is my unfiltered opinion.
My Issues with Feminine Hygiene Products
I’ve had horrible menstruation issues since I was a teen. Super heavy bleeding, fibroids, awful cramps, etc.
At some points in my life, I’ve had to use super tampons and super pads simultaneously, and there have been so many times where things have leaked and I’ve had to run home to change. It’s embarrassing and frustrating.
I mention this because I go through a lot of feminine hygiene products each cycle.
A few years ago, I decided to reduce the amount of chemicals I put on my body. One way I did that was by switching to more natural/organic tampons and disposable pads.
That was a great move at the time, and they worked well. My only issue with them was that the glue on the pads was so strong that it consistently ripped my regular underwear apart.
So, I had to throw away a lot of ruined underwear, which was a total waste of money.
All this rambling is just to show you my thought process and why I figured it might be worth trying out Knix leakproof underwear.
Honest Knix Underwear Review
Which Knix Underwear Products I Tried
There are several options when it comes to Knix women’s leak-proof underwear styles: Bikini, Boyshort, Thong, Cheeky, High Rise, and Dream Short.
In addition to these styles, you can also get them in Super Leakproof fabric and some in lacy fabric.
And they also have the following period panties sets you can buy: Heavy Flow Period Kit, Mixed Flow Period Kit, and Knix Starter Kits.
These are the ones I have personally tried and tested over the past few months.
Leakproof Bikini
These ones are medium absorbency and say they absorb 3 teaspoons of blood, sweat, or pee.
I’ve worn these on all days of my cycle, and they are mostly comfortable.
They are true to size, so don’t size down thinking you need to for leak protection. I made that mistake on my first order and had to size up for my next order.
These ones would actually be pretty awesome for pregnant mamas or ones who have a newborn at home because it would help with bladder issues as well as dealing with that first period after giving birth.

Leakproof Period Boyshorts
Boyshorts are my favorite style of underwear, so most of my period underwear is these boyshorts.
They have all the same features as the bikini style, but they provide a bit more coverage of my booty.
I wore them one time and immediately went online and bought a couple more. Super comfy and versatile.

The Dream Short
These are kind of like the boyshorts, but with even more coverage. They are sleep bottoms that can absorb 4 teaspoons of liquid.
Of course, they also have the patented leakproof technology.
I own 2 pairs of Dream Shorts and they have made sleeping while on a period so much more manageable.

What I Like about Knix Leakproof Underwear
Usually, when I get my period, it’s a mad rush to make sure I have all the supplies I need. And then my day revolves around changing my pads and tampons to stay nice and fresh.
Knix Period undies work so well that they take all that worry away because I know I’m all set, and I can go about my life stress-free.
I love how, on most days, Knix leakproof underwear makes me forget I’m even on my period.
They do an awesome job of absorbing odor. I never notice any smell (which I always do with disposable pads).
Plus, they are so much more comfortable to wear than tampons. They feel pretty much like regular underwear, except for a little stiffer panty liner area.
They come with a little lingerie bag that makes it really easy to keep them all together, so I always know where to find a clean pair.
And just as a side note: I really like that their website features real women of all shapes, sizes, and ethnicities, so I can see what the Knix panties look like on regular women.
What I Don’t Like about Knix Leakproof Underwear
I’m all about wearing full-coverage underwear (especially ones that eliminate visible panty lines!). I wear a lot of yoga pants during the week and don’t want them to show.
After a few hours, the Knix bikini underwear started giving me a wedgie, and I found that I was always tugging on them. I tried two different sizes and got the same results.
The Knix boyshorts fit a lot more like regular bikini underwear, which fit me better.
One thing I had to get used to was the feeling of putting on wet underwear the first time I had to pee when wearing the Knix leakproof underwear.
I only noticed that feeling a couple of times during my first cycle, wearing them, and haven’t noticed it since.
Knix Underwear Review FAQs
What is Knix Underwear made of?
Knix panties are designed with multiple layers of fabric, including a polyurethane film, which helps create a moisture barrier and enhances leak protection. However, this can make them feel a bit thicker than traditional underwear at first.
Will Knix Leakproof Underwear Work for Heavy Periods?
For the regular Leakproof underwear, I’d say no. After a life of super heavy flow, I think I’d need to change underwear every few hours, which defeats the purpose.
However, these would work well in addition to tampons. It would be like having backup coverage to help with any tampon leaks. It would provide a layer of protection (and give you some peace of mind).
I’m so glad that they recently launched their Super Leakproof underwear. These hold more liquid and would be perfect for heavier flows.
Does Knix Period Underwear Work Overnight?
Yes. I like to wear the Dreamshorts on my heaviest days and then the boyshorts on the other days. I’ve had zero leakage.
How Often Do You Change Period Panties?
It kind of depends on your flow. Some people recommend changing them every 4-6 hours during the day to stay fresh.
I usually change them a couple of times on my heaviest days, but wear them all day long on the other days. (I switch to the Dream Shorts when I put my kids to bed.)
Since Knix products are machine washable, it’s easy to cycle through clean pairs regularly. Just toss them into a mesh bag and use cold water with a mild detergent to preserve the absorbency and fabric quality.
Can Period Panties Replace Pads?
Absolutely. That’s pretty much what they are designed to do.
For women looking to avoid the waste of disposable pads, switching to absorbent underwear is a smart and sustainable option.
Are Period Panties Sanitary
Yes. Knix leak-proof underwear also has technology that wicks away moisture, which helps with personal hygiene.
How Many Pairs of Period Panties Do You Need?
You’ll want to wear 1-2 pairs of period panties during the day and another pair at night, depending on how often you do laundry.
Right now, I own 2 pairs of Dream Shorts and 5 pairs of regular Knix period panties. And I do laundry about every other day.
So, are Period Panties Worth It?
For me, Knix leakproof underwear has been a total game-changer when it comes to my period.
I’m no longer worried about having enough tampons on hand (in the right absorbency) or stressed about leakage.
They feel just like regular underwear and allow me to go about my normal day.
I also love that it’s less wasteful than disposable feminine hygiene products, so it’s better for the environment.
I don’t think I’ll ever go back after trying Knix period underwear.
