Thinx reviews and discussion

As far as period products go, these are a massive upgrade from pads, tampons, or cups in my opinion. For a girl who’s just starting to get her period, these are a far better option than having her figure out the period-care logistics of disposable products, and I wish I’d had this option then. There are some downsides though: they had some scandals a few years ago involving materials and business practices, and their elastic especially hasn’t held up as well as other similar brands I’ve used over the years. They also aren’t great for traveling, and will take away the camaraderie of being able to give another woman a tampon when she needs it, but these are minor, fixable issues.

I used to love this brand but they had some news spread about them about forever chemicals so I am hesitant to continue to use them; however they were great underwear to use while on period. However I used them more as insurance along with pad or tampons!

These are the best! I’ve been struggling to adapt to having my period again after having my IUD removed and Thinx has been an incredible and unexpected solution. I love the comfort and confidence they give me you get through the day (and night!) without worrying about a leak. I’ve tried other brands, but I keep coming back to Thinx

I'd been buying their products for my teen. I recently purchased a few more but newer ones don't have lining. I'm very disappointed and won't go back.

I really like my Thinx underwear and think they hold up well even if I don't always wash them in the ultra-delicate ways that help prolong their lifespan. I like these as backup products for overnight and don't find them too bulky, but I'm not wearing them during the day under regular clothes.

I wish they had something like this when I was in high school. However, the PFAs lawsuit is really a letdown and the reason I can't recommend them to others. The concept is amazing but the execution is lacking.

I used to love this brand. Had a lot of their period panties. But then I found out there was toxic materials in them and threw them all away.

When I first got these I was so excited about not having the use a tampon or pad at night. I was worried that I would feel like I would have a diaper on, but it really doesn’t. Unfortunately new research has come out that says there are PFAS in Thinx and there was a huge lawsuit. Wouldn’t use them again

If you are reading this you're probably wondering if period panties work. Answer: YES. Probably one of the most useful new products I've started using in the last 5 years. I use the period panties during the night, and would never switch back to anything else. High-waisted models are the comfiest imo. A huge plus for Thinx being available on the HSA Store.

It works!

I think the underwear is a good product for periods for soakage but the waistbands are horrid. 10 out of 10 pairs have a broken and frayed band after a year. Again, the absorption still works fine but the band quality is horrid

I really want to love them, the concept would be great. my period is extremely heavy that i have to wear a pad with these on and I still bleed through. theyre okay for when you are spotting and have lighter days, but for the price I don't know if theyre the best investment. I still get rashes when wearing them, and I still go through at least 2-3 pairs a day.

Messy and gross. Menstrual products are generally designed to limit mess, but these underwear constantly felt damp, couldn't wash/dry properly. They would also leak, and so are only appropriate for the last days of your period/spotting. I wish this concept could work, but it's functionally a reusable adult diaper.

Love the idea. Wasn't a huge fan of them as an actual product. I felt like I could never get them clean, and they started fraying pretty quickly.

My flow is pretty heavy and I have constant paranoia during my cycle. I bought thinx specifically for Machu Picchu (backpacking four days) and wow, when I say it held up and I didn’t have to worry about anything on the trek speaks words. It’s been a year and it has transformed the way I go about my cycle.

I used it only on heavier days, which made my first few days comfortable. I'm used to handwashing and I didn't have an issue with washing it. After a couple of years, I noticed they don't work as well as they used to, and recently I found out they have PFAS chemicals... which made me really sad. I switched over to The Period Company's washable period panties and it's been a good alternative.

It's a shame they contain forever chemicals because I found them to be so useful :(

wouldn't purchase again. the seams of the underwear dug into my thighs, which made them uncomfortable to wear. after one wash, i noticed that they lost their shape and the elastic wore down.

I have some cotton thinx in the shade of my body which is exactly the extra security blanket I need when wearing a white skirt or pants or dress on one of the later days of my period. It’s not super safe for the early days and I’ve had some leaks but that’s my bad because it does say on their website it’s only for lighter flow days. I recently ordered the super cotton pants in black and sleep shorts in grey and black and am excited to try them out :) big plus is that out of all the period underwear I’ve bought this one fits the best and is most comfy! Edit: I love (!) the heavy flow thinx! I've been wearing them (cotton boyshorts and cotton sleep shorts) for the heaviest part of my period the last few days now and it still blows my mind that it feels nothing like when wearing a pad. You know when you can feel everything down there and you're just like "where on earth is the closest bathroom I hate this?" It doesn't feel like that at all, I don't even notice that I'm on my period when I wear these. The one disappointing instance was when I tried wearing the boyshort overnight (I only bought two sleep shorts so I thought on the third night I'll just use a boyshort since I usually don't have much flow at night anyway) and unfortunately due to me moving around it did leak through the sides (luckily not onto my sheets but onto the outside of the boyshorts) - but I guess that's my lesson to only use the sleep shorts to sleep. Overall - 9/10, still a big big fan! Will purchase more :)

These are okay. I've been using Thinx for several years now as a tampon back up, but I don't trust them to contain my flow. They seem to spread beyond the edges even with styles that are designed to absorb more fluid.
