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.

Thinx is great in the fact that it offers such a wide range of styles and colors unlike many of its competitors!

As you can see, Thinx comes in a range of different colors and styles, which is just what every woman wants – a lingerie drawer full of exciting underwear to suit her activity, mood and style!

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!

    Where were these when I was in high school? I purchased one to see what or if this was a possible option for me. I can’t stand tampons. Love these and will buy some more and i have shared with friends.

  2. i tried it today & am so confused! i read great reviews & both the website & packaging says its leak proof. Well, i decided to try them on my last day when my flow is minimal & by minimal i mean that it is scarce! i wore them for 3 hours ( the ones that absorb 1 & a half tampon) & i rubbed a tissue from the outside; it stained bloody! so disappointed & mad actually for wasting my money but more for the fact that i thought they would be like they claim(something great)!

    Almost perfect. In my opinion, they provide too much coverage in the back and not enough in the front. I’ve leaked twice now over the front (once while sleeping, boy that was a mess). I don’t use them as backup to any other form of period protection, but I’m sure if I did they’d be great. I just can’t use tampons because it causes horrible cramps.
    On the plus side, I was afraid they’d smell or feel wet.. Nope!
    If they had more protection in the front, took less time to air dry, or could be dried in the dryer, they’d be perfect.

    I’m sure these panties would have been great…if they had ever arrived. Be warned international shoppers. I ordered these in march. When they still hadn’t arrived in May I contacted them and they offered to reship them. The driver for the delivery didn’t think to call me and just warehoused the second shipment in a town 45 minutes away. Also, they don’t tell you when you place the order but they don’t cover the duty charges so if I had of even received the panties I would have owed an extra $20 on top. $64 panties??!!! Not worth the trouble.

      I posted this review above. Although I was frustrated, in the end they ended up refunding me for the panties and still sending them. I’ve used them now and they work very well.

    These undies are life changing!!! I read a small article in a magazine about them. Then, I figured I would check them out on line. These are the best things I have purchased! I wore them on my heaviest flow day, and felt like I didn’t even have my period! They shipped very quickly, and I will be ordering more of these!!

    I’ve used THINX hip hugger period panties for two cycles and I really like them. I prefer to use them as a back up to my cup, but I tried the panties without a cup on my lighter days and it wasn’t a bad experience. The panties didn’t feel wet and I couldn’t tell that I was bleeding into my underwear which is awesome! The underwear is a little snug but I wouldn’t recommend buying bigger than what you normally wear unless you bloat a lot while on your period. The material has a nice texture and is really comfortable to wear even though they are thicker than regular underwear. I definitely recommend THINX.

    I love my THINX. I use them with tampons on my heaviest days. (And I’ve been looking into menstrual cups as a replacement for those.) I didn’t encounter the long-drying problem, but I have a dehumidifier in the area I hung them up. I highly reccomend them to everybody and am constantly telling people about them. They’re 100% worth the money. PLEASE do yourself a favor and buy a pair (if not more!) of these!

    I know. Try selling them on eBay. You won’t get back ALL you paid for them, but you might get back some. That’s what I plan on doing. The panties are thick, hot, and they actually cause smell, instead of stopping it. Just be totally honest about their condition and usage. Eventually they’ll go out of business. These liberal companies never figure that out.

    Good luck!
