Thinx has one of the best names in the business when it comes to period panties. They have a “One Woman” campaign (in conjunction with Harper’s Bazaar Magazine) which describes the lives of five extraordinary woman, who are all in male-dominated jobs, who rely on Thinx during their periods.

These woman have no time for tampons and pads, and use Thinx panties as the best solution for their periods – such as in the case with Grace Robertson, a champion firefighter, Fatima Sharfi, an accomplished pilot, Kiko Matthews, the fastest woman to solo-row across the Atlantic Ocean, Oona Tempest, sushi head chef and restaurant owner, and Tia Norfleet, the first African American NASCAR-licensed driver.

How Thinx Started

Thinx was created back in 2011 BY Radha Agrawal, Miki Agrawal, and Antonia Saint Dunbar. In 2018 a range for teenagers and tweens was created called BTWN, and in 2019, Thinx Air was released to the public, which is a version of their underwear that is quick drying.

Accolations

TIME Magazine named Thinx panties one of 2015’s best inventions! In 2017, Fast Company Magazine named Thinx one of the most innovative companies of the year!

How Thinx Works

Thinx is super absorbent, holding up to 4 tampons’ worth of menstrual blood. It wicks moisture, as its breathable cotton takes away all the wetness, and dries fast. It controls odor, neutralizing smells keeping everything fresh all day, and is leak-free, preventing any kind of stains.

Frequently Asked Questions (FAQ)

Do Thinx really work?

Thinx really does work! They are one of the game changers in the business.
They put a lot of effort into their period panties making sure that they’re leak proof, and stain proof.
Although there are many other period panties out there, few can claim to hold up to as many tampons worth of menstrual fluid as Thinx can – up to 4 regular tampons for certain styles.

Can Thinx replace pads?

Thinx is the ultimate solution when you’re sick and tired of having to use uncomfortable tampons and sticky sanitary pads that don’t always fit comfortably, sometimes even shifting.
Thinx is actually better than pads as they are a better alternative to menstrual care for the environment.
Over a lifetime you will also save so much by not using pads anymore.

How long can I wear Thinx?

You can wear Thinx between 8-12 hours. It all depends how heavy your flow is. But, that’s why Thinx is so convenient!
It has such a big range of different styles depending on how light or heavy your flow is!
If your period is really heavy, you’re going to want super absorbent styles. If your flow is extremely light, you can wear their Thong.

How do you clean Thinx?

Thinx is simple to clean! First rinse them in cool water.
Then place them in a special lingerie bag or enclosed pillow case in the washing machine. Wash them only with other delicates, at a cool temperature.
If you don’t have a washing machine, rinse them in cool water first, then gently apply washing liquid, wash carefully and hang to dry.

Does Thinx feel wet?

Thinx creators made sure that all Thinx period panties have a moisture wicking layer, so that they don’t feel wet.
They also have a layer that is absorbent, so that they don’t leak and cause unnecessary embarrassment for anyone!
The material is lightweight, so it never feels bulky, or like you’re sitting in a puddle of water. They really are great!

Why do my Thinx smell?

If your pair of Thinx smells, it could possibly just be that you’re having an extra heavy flow, and have gone past the 12-hour mark without changing them.
Also, if you sweat a lot, or have been working out with them and haven’t changed them for a few hours, they may smell.
Always make sure to shower every day when having a menstrual cycle.

Does Thinx smell?

Thinx’ special technology in their wicking layer absorbs all traces of menstrual fluid. It has an application of non-migratory silver to control odor, as well as the spread of any form of bacteria.
“Non-migratory” only responds to bacteria specifically on the fabric, and not on your skin.
This way your vaginal microbiome will remain fresh and balanced.

Do Thinx work for urine?

Thinx has a sister brand called Speax. Speax is designed specifically for incontinence. It’s bladder leak protection on the go!
Speax holds up to 8 teaspoons in liquid! They keep you dry, and are odor resistant.
They come in 5 classic styles – Hi-Waist, Hiphugger, French Cut, Bikini, and Thong. They also come in a range of really stunning colors and patterns!

Can I wear Thinx for 24 hours?

No, Thinx period panties are to be worn for a maximum of 12 hours. After 12 hours you need to take them off and simply put on a new pair.
If you are at home, immediately rinse them. If you are elsewhere, simply pop them in a packet and put it in your bag to be washed later.
No panties should ever be worn for 24 hours, neither should a menstrual cup, tampon or sanitary pad. (300 characters)

What happens if I put Thinx in the dryer?

If you put Thinx in the dryer they will slowly, over time, not perform like they should. You should NEVER put them in the dryer no matter how convenient it is to do so.
It is always recommended to rinse, wash, and then let your pair of Thinx hang dry. Even when they do hang outside, you should remove them once dry.
Thinx should never be in a lot of heat for too long.

Are Thinx toxic?

The CEO of Thinx, Maria Molland, has said that Thinx’ customers’ health and safety are their number one priority.
She mentioned that they work to put out the safest products available, and that all Thinx and Thinx (BTWN) underwear go through exceptionally stringent product safety evaluations.
She said Thinx’ products are always being improved.

Can I use vinegar on Thinx?

Yes, you can! You may be curious how they help!
If you feel that there is a scent left behind in your underwear, submerge them in a basin or sink with 1 to 2 cups of water, and 1 cup of vinegar.
Then, leave them there for 15 to 30 minutes. Afterwards, put them in the washing machine.
Do not use balsamic or apple cider vinegar, just regular vinegar will do!

Is Thinx hygenic?

Thinx period panties have been developed with a very special patented design that takes away all bad odors, and bacteria.
They are also exceptionally absorbent and sweat wicking, so they keep you fresh and dry all day long!
A lot of science has gone into Thinx, making them truly hygienic. You must shower every day of your menstrual cycle for perfect hygiene!

    I really love my Thinx leakproof panties. I wear them on their own (no diva cup, tampons, etc). It’s a new concept to me so it is sort of hard to build up the trust at first, I’m still testing the limits.

    My favourite ones are the boyshorts– I wish I had gotten enough to wear those all week long. They look like shorts, rather than undies.. so I just wear them around the house.

    These are my first leakproof panties, and I definitely don’t have any regrets, but I am curious to try out other brands as well.

    + PROS: Comfortable, reliable.
    - CONS: They are a bit expensive, but so is a lifetime of buying pads, tampons and replacing regular underwear that you'd bled into.

  2. Wanted to try them but was turned off by their feminism and left leaning propaganda. I’ll spend my money with a company that doesn’t push their political agenda on their consumers.

    I like Thinx though there are some issues. I wish they didn’t cost so much.
    I have a light-medium flow (due to Liletta IUD) and don’t need to use tampons or anything else when I wear these.

    + PROS: Good quality fabric Absorbent Variety of style and color options Look good Fit well Comfortable
    - CONS: Expensive Smell bad after a while Difficult to wash Very difficult to dry properly. I think you need to live in the country with good weather where these can hang from a line in the wind and sun.

  4. Bought these for my teenager and she LOVES them! We just ordered more the only downside is the price. She has never had a leak and she has a pretty heavy flow the first two days.

    I don’t think these are worth the cost. they are $30. 00 a pair a purchased 3 pair its been about 6 month sand they all need to be replaced because eth mesh band has come apart on all of them rendering them useless.

    + PROS: make you feel more secure than regular underwear.
    - CONS: Poor craftsmanship. very expensive.

  6. I am checking out all these reviews, because after having 7 pairs of Thinx for two years, I have finally decided I need another 7 pair so I can get rid of all my “regular” panties and wear these full time. But, I decided to see what other choices are available. Why? Because why not? I like to do a little market research before spending >$100.

    So in two years of wearing Thinx, I have never been disappointed. I do still wear tampons two days a month, when I can soak a super in just an hour. Where Thinx has come through for me is stress incontinence. I can sneeze or cough and I’m covered. I have a spare in my purse in a watertight container and have only used the backup ONE time at work, when I had been in a first-grade clas sroom all morning and got a coughing fit. The panties were sopping wet by the time I got to the bathroom to change, but there was no leak.

    I haven’t noticed a smell either.

  7. Pretty pricey so I thought it would perform well. I have some leaking and they were really uncomfortable. Disappointed. 🙁 Save your money and pass by these products.

    Very Disappointing. I have very light flow and my mid-day I was leaking and smelling. Not sure what tampons they compare to but definitely not 2 tampons worth. And I want to know whose hips the hip huggers are for. Very uncomfortable.

    + PROS: refund policy good.
    - CONS: Slippery, too low for hip huggers smell not 2 tampons worth Expensive

    I have had one pair of Thinx black boy shorts for over a year now and they’re wildly comfortable. Also, I’ve never had a leak. Sounds great, right?

    The things is this fabric smells so dang awful that I cannot recommend these to anyone. When I first read the review by an author from the HuffingtonPost mentioning the awful smell of Thinx period panties, I naively assumed the author simply had a funky smell to her, (apologies my dearest damsel! I had no idea. The future me can definitely state now: It’s not us. It’s them!). Furthermore, the smell does NOT go away after washing. It wasn’t something I noticed right away but now that the smell is there, it’s there for life.

    However, I HIGHLY recommend period panties to everybody, so it’s just a matter of finding a fabric that doesn’t leave you questioning everything you ever thought you knew to be true about your own hygiene. I’m pretty excited to try ModiBodi. They too have the boyshorts style that this athlete has grown to love. Plus, because I’ve purchased bamboo socks in the past, I know bamboo fabric really does help “eat” my fella’s foot odor. (Yes, I realize bamboo is not a sustainable fabric like many would believe but regardless, it’s hard to deny the plus sides to it). I didn’t think I had to worry about odor but now that I’m scarred from my expensive Thinx experience, I’m hypervigilant about choosing an odor-reducing fabric.

    Thank you to everybody who has posted. It’s always great to hear other’s experiences, both good, bad, and “meh”.

    + PROS: ~The boy shorts are so comfortable for sleeping in at night or for being active during the day. ~I've never experienced a leak.
    - CONS: ~The smell is outrageously bad with the fabric they use. ~Did I mention the smell? ;-) It's so bad, I can't consciously recommend them to anyone.

    • You’re absolutely right about the smell. I noticed the funky smell thru my jeans one day. I was horrified and could only pray no one found out where it was coming from. I plan on selling them soon and will buy another pair of modibodis.
      You’ll like Modibodi. I bought one pair and when I took them out of the package, it looked as though they would be way too small, but I tried them on anyway. They fit beautifully and were so comfortable and felt like a second skin.
      Also, because of recent trade deals between the U.S and Australia, there are no more exorbitant fees. I can’t remember if I still had to pay shipping, but the pricing was way down.

    Mine have not arrived yet so my review is solely based on the process of getting them not the actual product. I’m UK based and just had to pay a £13.40 customs charge. So just wanted to warn all my UK friends out there: expect a hefty charge on top of your order. Info think things could place more emphasis on pointing this out to costumers as they’re trying to expand on their European market. A review of the product to follow ( once they finally arrive 1-2 cycles later…)
