Disclaimer: In this post, I will talk openly and honestly about my period and the existence of periods in general. If this bothers you in some way, I’m sorry that you won’t really enjoy this post, but I feel this is an important topic that women often feel unable to discuss. Periods are a real thing that half of the population has to deal with, so let’s just talk about it. Thanks for reading!

I’ve been hearing about THINX period underwear for a long time. I’ve seen their ads, read about other bloggers wearing them, and finally, a couple friends of mine tried them and swore they were life-changing. So on my way home from my sister’s bachelorette weekend after I’d discussed these underwear (and so many other things) with a bunch of amazing women, I finally ordered myself a pair. From my phone, no less, because I couldn’t wait to get home and order them.

“(Three friends)
+ (some gnarly period accidents)
+ (100 million girls missing school just b/c of their periods)
+ (3.5 years of R&D)
+ (like, 30 badass team members)
= the THINX you know and love and bleed into today.”

What do you mean “period underwear?”

THINX is this company that has created underwear that can replace tampons, pads, cups, whatever. You literally just #freebleed, or if you have really heavy days, they can back up your tampon or cup. Naturally, I think everyone is a little skeptical at first, but let me just say: they work.

“THINX is made up of four bits of tech that makes ‘em anti-microbial, moisture-wicking, absorbent, and leak-resistant.

The top layer fights bacteria and absorbs any liquid into the über thin layer right beneath it, so you always stay dry (and fly, obvi).

And no, they don’t feel like diapers, and it’s not like sitting in your own blood. Boom.”

All of the above is true. The magical technology THINX uses for these underwear absorbs the menstruation without you ever feeling icky down there. I wore mine in the middle of my period, which is a pretty moderate day for me, and it was seriously the best feeling. No worrying about changing a tampon so I don’t get Toxic Shock Syndrome or whatever, no accidents that ruin my favorite underwear or clothing, and I didn’t feel uncomfortable like I do when I wear a pad. I just… like… lived my life. While on my period. I’m not sure that this has every happened since I first started my period when I was 11.

I purchased the Hiphugger style, which will hold up to 2 regular tampons’ worth of blood. That is plenty for me, because I have an IUD and my periods are pretty moderate anyway, but you could easily wear a tampon first, and then use the underwear as backup. One of my friends who tried these said that’s what she did the first time she used them, but quickly realized she didn’t really need to do that. These things just work.

I think I will buy the Hi-waist style next, and maybe the Sport ones for when I workout. They now have workout clothes, too, and even a pair of running shorts that work like the underwear do! And yes, they even have a thong.

The price might seem a little high for a typical pair of underwear. But these aren’t typical. Like, at all. I hate math but let’s do a little bit.

A box of 18 tampons costs about $4 at Target. If I use 3 tampons a day for 5 days, that is only enough to get me through one usual period. If we use that scenario, I am going to need 216 tampons this year. So every month, for a year, I have to buy a box of at least 18 tampons. I could get a box of 50 for about $10, but that’s still only enough for about 2.5 months. At Sam’s Club, you can get a box of 96 for $12. Still not enough, though.

No matter what you do, I’m spending at least $40 a year on tampons. And that’s not even including the price of pads or liners, if I want those, too. Not to mention, a lot of tampons have weird synthetic ingredients that we are literally putting straight into our bodies. So there’s that.

One pair of THINX underwear costs between $29 and $39. And you can use it all year.

So, what about washing them?

First, you rinse them out in cold water. Then you just wash like you would any other delicate, but don’t use bleach or fabric softener. They recommend you use a mesh laundry bag made for delicates, too. Then, you let them hang dry.

That’s it.

Then you can wear them again the next day. Or if you have multiple pairs, you would obviously just wear a clean pair. Since I just have the one pair right now, I’ve been hand-washing them at night and then letting them dry for the next day.

What else?

Besides making game-changing underwear, THINX uses a “buy one-fund one” model with its sales to globally provide reusable menstruation products and education to millions of girls. They also work to eliminate the shame associated with periods in these countries. I mean, let’s be honest, I felt the need to give a disclaimer about this post and I live in the United States. So there’s some shame going on here, too. I think it is so important and inspiring that THINX made it their mission to help the women of the world in this way.

On top of that, reusable menstruation products help lower our carbon footprint. Where do you think tampons and pads go when you dispose of them? Not to Period Heaven, I’ll tell you that. Using these underwear will help reduce or eliminate our need for other types of disposable items. And, if you’re like me and using a cup just doesn’t seem like something for you, these underwear might be the way to go. Help the environment, help others, help yourself. It doesn’t get much better than that.

“We’re providing girls worldwide with safe spaces to learn about their bodies, enhance their financial literacy and explore their entrepreneurial potential, all while changing the global narrative around menstruation.”

My aunt also brought up a really awesome point one day as we were discussing and being mesmerized by the existence of such a product. My aunt works in Special Education and sometimes works with students who are severely mentally impaired. They might be an adult physically, but mentally are much younger; therefore, these students might not be mentally able to “take care” of their periods. She said this type of underwear could completely change these students’ lives. How incredible is that?

I know of several similar companies like this one, and more keep popping up, but this is just the one I decided to try. I’d love to know if anyone else has tried these or some from another company and what you think. I think by opening up this dialogue, we can more comfortably discuss something that effects so many of us on this planet.

    Kayla, amazing post (as always)! When I read your posts, I seriously feel like you’re sitting right next to me just hanging out & talking.


    OBVIOUSLY, you know I love THINX, but I want everyone else to know how freaking wonderful they are!!!! The other day, I wore mine the entire day & rode my bike for 6 miles with my church people in the evening. I LITERALLY FORGOT I WAS ON MY PERIOD & thought “Crap, I wonder if I’m going to bleed through these period panties.” After I got back home around 8:30, I checked & nothing. These miracle underwear (made by God, angels?) had absorbed everything. No leaks. Nothing. ALL DAY PEOPLE + a million degree bike ride.


    Put a pair on before Rails & Ales last Saturday (around 3pm) & FORGOT AGAIN that I had them on & didn’t take them off until I showered again SUNDAY around 5:00pm. (Sorry friends if this is gross– but I just NEED you to understand the wonderful-ness of these panties.) Once again, no leaks or anything….. HOW?

    I would also like to add that I have three pair of the “hiphuggers” – I will have a pair on, have a pair in the wash & have a pair air drying. Perfect cycle for your cycle (ha).

    Every single girl in the world needs these. Every. Single. Girl.

    Sammi Jo! Thank you SO MUCH for sharing all of this! I’m going to have to post it on the thread on Facebook or something to share with everyone. Seriously, INCREDIBLE. The bike ride is the most impressive to me. Like HOW?! I like your system with the three pairs in rotation. I need to shop for some more…like is it weird that I just want to wear them all the time?

    And yep. Every. Single. Girl. ❤️

    YEPPPPPP. These are a Godsend, people. Add 3 pairs of hiphuggers to your cart, enter your card info, close you eyes and go for it. (Or do like Sammi and create 3 different accounts to use 3 different $10 off discount codes…) Yes, they are expensive but they are 100% worth it and will change your period forever. I have 4 pair now (one was an exchange because I ordered the wrong size and they replaced it + let me keep the other pair) I have 2 hiphuggers and 2 sport. The sport are nice but kinda give me wedgies which is not ideal on my period so I just sleep in them and wear the hiphuggers all day at work. (Word of advice: I think the sport run large and would recommend sizing down. I ordered a small because thats what my hiphuggers are but they were super loose on my butt… but they replaced fo free so I wasn’t mad.)

    Anyways, everyone just buy these. Just do it. You will totally stop caring that you are even on your period and you can proceed with your life without worrying about changing your pad/tampon/whatever.
