Honest Thinx Review

I saw Thinx ads all over social media for MONTHS before I decided to buy a pair and try them out. I actually contacted them first to see if they’d be interested in doing some kind of sponsorship or something and they politely declined, but STILL, I couldn’t shake my curiosity! I had to try them out, so I bought them with my own money instead.

And two months later, I bought two more pairs because they were THAT impressive. So despite the fact that they wouldn’t work with us to get you a coupon code, I still highly recommend them 😉

What are they?
Thinx claims, “our period-proof undies hold up to 2 tampons’ worth — yet they look and feel like regular underwear.” Those are some big claims! And at first, I was totally freaked out at the whole idea, but the more I saw them, the more curious I got .

– A bit pricey
– The panty lines are real with the athletic cut (as in I could see the line through jeans, but that only matters if this sort of thing bothers you).

– Insanely comfortable.
– They WORK.
– They wash well and NO, they don’t stain your other clothes in the wash cycle.
– You can’t see the thong through yoga leggings.
– True to size.
– They actually look nice! No granny panty status over here! They don’t look the least bit medical or special at all. They look like a basic black panty which I love!
– I haven’t had babies yet, but I can image these would be so comfortable and easy to wear after you give birth. Maybe as an alternative to those ugly medical underwear they give you once you go home?!
– Eco friendly. They’re washable so you can wear them over and over. A nice alternative to a diva cup, or just a nice way to cut back on tampons and pads?! I think so!
– These would be SO amazing for teachers or nurses or any professionals that have a rigid schedule or can only take limited breaks.

I still wear tampons but the briefs are fantastic for overnight or when you’re going to be out for a while and aren’t sure when you might be able to get to a bathroom. In other words: they’re great for giving you peace of mind about potential leaks. The thong holds 1/2 a tampon’s worth and works PERFECTLY for yoga.

Other stuff you might want to know:
– My hips measure 36.5″ and a small fits me perfectly
– I still wear a tampon except for light days just because I feel more secure that way. I wear them overnight & on heavy flow days because it gives me peace of mind, and I’ve never had a problem or any leaks. That’s more than I can say about tampons! Really impressive.
– They also have a pair that holds 2 tampons worth but I didn’t get that one to try. I can imagine it working just as well as these though.

So that’s it! I just wanted to give you an honest review of these since I’ve seen them EVERYWHERE and I knew I couldn’t be the only one who was curious about them.

Over to you! Have you tried these? Would you ever try them?

    Can I ask why you don’t use a diva cup? So much better for the environment than tampons and much better for you as well!

      Hey, I can’t speak for Erin, but I use tampons with my thinx too because I have endometriosis and adenomyosis and I find the cups actually cause flare ups whereas tampons are less likely to due to the shape. Tampons sometimes ititate a bit, but not as severe or consistently as I’ve found cups too. They’re just far too uncomfortable and sit in all the wrong places triggering horrific pain for me.

      I write this because I have seen so many people pushing the cups and the fact is that some of us simply cannot use them, but I’ve seen people online get quite adamant that we are just using them wrong or need to try a different cup. We aren’t, and I’ve tried different cups with the same pressure resulting.

      They just don’t work for everyone.

        I agree. I don’t use tampons though, I use the cloth reusable pads. The cups I’ve tried always caused me to have really severe cramps. Plus any insertables are uncomfortable to me due to a problem with the remains of my hymen. Some people really cannot use them. Thinx are something I’ve been thinking about for a while so it’s nice to see another alternative that helps the environment a bit more and actually works.

        Yes! Cups do not work for endo and tampons don’t either sometimes. I use cloth pads most of the time because of my endo.

      How a person chooses to deal with their period is frankly no one’s business but theirs. It’s not up to them to justify to anyone WHY they choose to use one product over another. Whether it’s just their personal choice, or they have a medical condition that makes one product more comfortable or convenient than another – both are completely valid and reasonable explanations. This is not an area that is acceptable to question or shame a woman for choices about her body. It feels like your question comes from a place of judgement and moral superiority. If I’m wrong, I apologize.

        You are the reason I post anonymously online if I ever take part in a discussion at all… Everyone is so quick to judge, attack and put down other people on the internet. Maybe you should look at why a small two sentence comment literally just asking question, with no judgement or shame at all, made you outburst like you did. She posted a blog post about using THINX / tampons for her period so I asked about a diva cup out of genuine curiosity as it’s something I imagined Erin would’ve tried or used.

      i HATED the cup! could never get it to fit/work right. i kept it to revisit a different time, but as of now, it’s a hard no, haha. i use organic products otherwise as a better choice, but as others have said, what works for one certainly doesn’t always work for all 🙂

    I tried these back when they first came out. I had a pretty negative experience with the company. I think they were overwhelmed with orders, they processed my order, continued to delay shipping the undies but still charged me for them. When six months went by and I still didn’t have the undies I knew there was something very wrong. Throughout the time I had continually reached out by email and phone ( I really hope they have someone answering and responding to phone calls now). My last email to them let them know I didn’t know what else to do but to report the case to the better business bureau since it seemed like they were pocketing my $300. So I did and a week after my undies finally shipped. They also refunded me. So I got six pairs for free but never any acknowledgement over what had occurred. I am just now realizing I still feel bad about the whole scenario.

    As for how the undies performed, the first three months I loved them. I followed all the washing instructions and hung them to dry just to make sure they lasted and were as effective as possible. I have very sensitive skin and found the lace coarse and it did leave irritations on my skin,common with most roos for me.

    Six months in and the part that catches everything began to discolor, turning beigey white (black originally) and the undies developed a weird chemical smell. I felt like maybe my detergent, so I switched to an amazing all natural detergent that I still use.

    I ended up discontinuing using these after a year and a half, I started getting all kinds of nasty irritations from them. Went back to my cup and organic panty liners. There’s another brand out there I may try eventually, less expensive too, called Dear Kate. Maybe eventually.

    I got a size up from my usual, the sizing chart was misleading, because these undies do not have much stretch to them at all.

    In any case, good stuff to share! Thank you for all you do.

      I bought them when they first came out as well and bought new ones a year or two later. They are so much better now (more comfortable and breathable) and they have repaired the issues with their sizing. The lace is also different now. Just figured I’d let everyone know.

    Hi Erin!

    So great to see that you’ve started to go an eco friendly route in terms of your period. I was planning on trying the thinx underwear until my sister mentioned she started using a cup and LOVES it. This website actually lets you take a quiz to determine which cup is right for you. https://putacupinit.com/quiz/ A menstrual cup sounded scary to me at first, but she said once you get the hang of it, its really easy. And it is like a tampon in that you don’t really have to deal with the blood until you take it out. I haven’t gotten to use mine yet, but my sister says she just puts it in when she takes a shower in the morning and then empties it before bed. She said she’s worn overnight with no issues (medium flow). She has the Lena and I ordered the Lena sensitive. Apparently there’s also lots of helpful videos/tutorials/articles online if you have questions/issues on how to use.

    As I was doing some research on the cup, I also saw some bad press about the thinx underwear which turned me off. Sadly, the company’s founder and former CEO has been accused of badly mistreating employees. For this reason, I just can’t support thinx even if they have great period panties. Here is a link to the article on the controversy, which also lists some great period panty alternatives. https://putacupinit.com/thinx-alternatives/ #anythingbutTHINX

      i have a cup but absolutely hated it! couldn’t get it to fit properly and just kinda gave up after that. i kept it to try again later, but yeah– not a success for me! also read about someone getting it suctioned TO THEIR CERVIX and that pretty much turned me off altogether lol.

        June 29, 2018 at 9:27 pm

        Thanks for responding Erin! 🙂 Glad to hear you gave it a try! Not everything is a winner for everyone. Actually not at all surprised to hear that some people have had it get accidentally suctioned to their cervix since it works by creating a light suction inside (just hopefully not attaching to the cervix). Lots of stories about tampons/condoms getting stuck too, but they are more widely used so people don’t seem to get scared away as easily. Maybe a little less traumatizing?

      I love my Thinx and was disappointed a while back to read about Agrawal’s behavior. Maria Molland Selby is the CEO now though and she has stepped it up. I’m much happier to be a Thinx customer now.

        June 29, 2018 at 9:36 pm

        Its definitely good news that they have a new CEO who has been making a lot of positive changes for the company. I am concerned as to whether Agrawal would still be receiving a portion of the profits since she is the founder. I couldn’t find anything online to see whether or not this is the case. Does anyone have any idea? Otherwise Lunapads are supposed to be another great period underwear brand.

    I have never tried these since my period is pretty heavy and if you have the wear a tampon with them, it sort of defeats the purpose.
    I switched to a menstrual cup a few years ago and never looked back. It was the best decision I ever made. No more drying out and they’re so comfortable I don’t even feel like I have my period most days.

    I love my Mooncup! Treated myself to one following a miscarriage earlier in the year…figured if I was going to have periods again why not have them without the frustration of spending so much on tampons. I don’t know why I didn’t switch sooner, it’s fab!! These undies sound like a great alternative if a cup isn’t your thing though 😊

    I’ve have similar ones from Knix, and they’re fantastic. I use them in lieu of panty liners (so with a tampon during heavier days and alone on the days leading up to and the wind down from my period) and they are soooooo much more comfortable, especially for fitness or if you’re going to be warm or sweaty at all. Highly recommend.

    They also sell ICON…underwear for those of us with a little bladder leaking problem. They work amazing!!! I can finally work out again, run, jumping jacks, and sneeze or cough without having to worry about needing to change my undies. So, for those of you needing a little comfort with pesky bladder leaks…I highly recommend the ICON underwear.

    I bought them within a year of them first coming out. At the time it was recommended to buy a size up, because they ran small. I have larger hips (44″), so I bought the largest they had in two different styles. (The two tampon holder and the lace one).

    I have a fairly lite period, but I still used them with a tampon for the first two months. I noticed a terrible oder if I wore them all day (my guess is because it is made of a heavy polymer material), and they fit horribly! The two tampons worth saged tremendously, and the lace one really wanted to become a thong.

    I kept trying them, because I loved the feeling of freedom I got, so I tried them without a tampon for a standard flow day. I went to a museum that day, and after 5hrs it had completely overflowed, stank horribly, and was giving me a rash.

    I pretty much stopped using them after that. I read in these posts that they have gotten better, and now have a more breathable panty. Maybe someday I will try them again.

      I bought the new cotton briefs that holds 2 tampons, I wore it all day at work on my normal flow day, no smell, no overflowing and no rash. I hope you can try again one day!

    June 27, 2018 at 12:49 pm

    Yes! I do use them, but not all the time. I mainly use the briefs for overnight use and I use the thongs in conjunction with my diva cup during the day sometimes. Though I still mostly use panty liners during the day, just because I can change those a lot easier than I can the thongs while I am out and about.

    I have one on right now! I’ve been using menstrual cups for years but lately had some mild irritation problems so I wanted to try something different and I kept seeing the ads for Thinx. They’re pricey and I had to add the custom tax wich was not a nice surprise, but so worth it! I have a very short period and a not so heavy flow so I’ve invested in enough of briefs, athletic cuts and thongs to be able to wear them without a cup or tampon for the whole duration (nights and days). So far so good! Not a drop overflowing (I can’t say the same about the cup, “hello slightly wrongly placed cup because I’m in a hurry”!), the briefs are perfect for the night. And yes, I agree, the panty line on the athletic cut is visible but not too bad (I wouldn’t wear them with my tightest thinest trousers). Sizing is perfect. I usually buy my underwear a size above because I hate being a little tight in them, but I stuck to the recommended size this time and they fit perfectly.

    These have been a game changer for me. I’ve been using them for over a year and the peace of mind it gives me is invaluable. Ever since I got my first period the idea of not knowing the day my period will start can be stressful so sometimes I will use a pair a day or two before it’s supposed to start, just in case. Again, peace of mind and definitly more comfortable than pads or liners for me. I still use tampons because the cups didn’t work for me, and it’s heavy enough for needing more than just the Thinx. As for working at a school and hospital, I have already lost count of how many times Thinx eased my mind when my schedule didn’t allow me to run to the bathroom. Also great for Pilates,yoga, and long plane rides across the country. I tell all my friends about them I love them so much. I do agree sizing is a bit off depending on the style you choose.

    Similar to thinx panties, I’ve been using the reusable pads and pantiliners made by hannahpad! I love using something that is such low waste towards the environment! It’s a little bit more work when it comes to washing them, but soooooo worth it in the long run! And as Erin said, these types of products are perfect for nurses or anyone else who spends a good chunk of their day busy on their feet. After a 12 hour shift, I’ve never had any worries that I would be leaking through/around my hannahpad. The huge changeover that many women are making towards reusables is so awesome!! Keep using whatever method you feel comfortable with ladies whether it’s cups or reusable pads or underwear!

    I love them. I bought a pair a few years ago, but recently bought more because there just that great. I have what I would call a normal cycle, not too heavy or light, lasting around 4-5 days every time. I wear them with no tampon ever, because I feel so much more comfortable, free and healthy. I’ve never had a leak, and I bought the bikini cut which I wear all day/overnight. So good, women everywhere should have a pair.

    June 27, 2018 at 7:41 pm

    I love them! I bought 3 pairs over a year ago and I still use those. I also recently bought some more. They’ve definitely improved the look and styles. I have a very short (3 days at most), light period, so I wear them alone and they work great. I can even wear them to work without worrying about leaks. It feels so good to have something reusable. And they are a bit pricey, but I feel like I’m saving SO MUCH money in the long run since I no longer have to buy something every month.

    I have some questions, Ladies!

    How on earth do they work? I would love to look into buying them, I can’t really wear tampons, but do and suffer through.

    So, you don’t have to wear a pad or tampon AT ALL when wearing these?

    How long can you wear them?

    Do they absorb like a pad would?

    Do you get all messy down there?

    Do you feel the “moisture”?

    Does it seep out the sides?

    (Don’t laugh) Is it like suction cup undies?

    HOW? I just can’t seem to wrap my head around this?

      So, you don’t have to wear a pad or tampon AT ALL when wearing these? I don’t- I mean everyone is different but I go through 2-3 of the thongs on an average day and wear the briefs to bed at night
      How long can you wear them? depends- see above
      Do they absorb like a pad would? Yes they absorb any moisture
      Do you get all messy down there? nope
      Do you feel the “moisture”? nope
      Does it seep out the sides? nope! haha
      (Don’t laugh) Is it like suction cup undies? no they just have an absorbent material where the lining is on regular under wear, it’s slightly thicker than normal underwear but are so amazing!

    Another option if you’re also thinking about birth control – try a hormonal IUD! I’ve had 3 Mirenas (including one now) and I never get my period. When I switched to a copper one because I was going to start trying for a baby in the next 2 years and it was only a 3 year IUD, I got my period again and it was shocking after not having it since 18! I got pregnant on our first try and then after the baby, I had a Mirena put in again and no more periods again (I had one post-baby but pre-Mirena, despite still breastfeeding). I do have spotting sometimes, which I didn’t have with the first two Mirenas, but I don’t need anything more than a pantyliner for it, if anything.

    I’ve loved having a Mirena, it’s super cost-effective if you don’t get you’re period since it’s covered by insurance (I didn’t buy pads or tampons at all for 10 years!), and it’s a lower level of hormones than even the lowest hormone level birth control pill.

    One of the greatest things about reaching the age of menopause is that I no longer have to deal with the monthly visitor, spend a lot of money on tampons and other cycle-related needs, and keep ruining my underpants even though I always tried to be prepared. Especially during the last few years I would get surprised a lot and my friend would arrive sooner than I thought. And my periods got so heavy at times that I felt like I needed a diaper, but I would have tried using a tampon and a pair of these panties. None of the stuff that is around now existed back when I needed it. I think there was talk of the cup, but it was not as popular then and was hard to find. I am still not certain hot flashes and constant peeing are a good replacement for my periods, though.

    There is no way these will hold up to postpartum bleeding, FYI for the future. Mine leak in just a few hours – nowhere near the 2 tampons’ worth they claim. That being the case, you would get about 30 minutes from them after having a baby. I’m all about reusable usually, but for postpartum bleeding get yourself some Depends.
