Created with AI, based on recent reviews

THINX is rated 2.3 out of 5 by 25 shoppers, with deeply polarized opinions. A significant portion of reviewers praise the core product concept and functionality, with some satisfied customers appreciating the basic performance of the underwear itself. However, the majority of reviews highlight serious concerns about customer service, return policies, product durability, sizing inconsistencies, and marketing practices. Shoppers report difficulty reaching human representatives, complicated approval processes for returns, unexpected size changes during checkout, garments that deteriorate within a year, and promotional claims that do not match actual discounts. Several reviewers mention involvement in legal disputes regarding product claims and chemical composition, which has compounded trust issues.

The most frequent complaints center on accessibility and accountability. Customers describe an automated support system that prevents them from reaching actual staff members, leaving returns in limbo and complaints unaddressed. Additional concerns include import taxes adding unexpected costs, performance that does not match advertising claims, and sizing that runs large or uncomfortable in fit. While a minority of shoppers report satisfaction with the product itself, the company's customer service infrastructure and transparency around pricing and product specifications emerge as the primary drivers of negative feedback.

Jordan B.Dec 19, 2025

It seemed like a solid concept, but the actual product just didn't perform the way I was hoping it would.

Angela F.May 21, 2025

Stay away from this company. Returning items with Thinx is practically impossible because they've set up so many obstacles to reaching an actual person who can help. You need approval before you can even send something back, and the approval never came for me. I kept going in circles talking to their automated chat system and eventually just threw the underwear out because it was too frustrating. I also found out after I'd already bought that Thinx has a class action lawsuit against them because they put PFAs, which are toxic chemicals, in their products while lying to customers about it.

Nicole G.Oct 24, 2023

The actual underwear works fine, but how they sold it to me was pretty sketchy. I ordered items that were on sale and somehow the size switched without me noticing as I was moving from selection to checkout. I normally wear a large, and somehow I ended up with multiple pairs in size 1X and 2X, which is absolutely huge on me. There's no way I would have intentionally skipped over other sizes to order something four times too big. They insist I'm the one who ordered the wrong sizes, but that just doesn't make sense.

Patricia W.Feb 20, 2023

I've been trying to reach out to this company for weeks about the federal lawsuit they're involved in, and they completely ignore my messages. They're being sued in court for making false claims about their products and allegedly using harmful chemicals that they said weren't in there. I was asked to join the class action but decided to pursue my own case instead since I've trusted their products for years based on what they said. I'm really worried about what damage their products might have caused me over time. Anyone thinking about buying from this company needs to know they're currently in legal trouble for false advertising and potentially dangerous materials, and you should probably stay away.

Victoria S.Jan 24, 2023

I got hit with import taxes, which I get isn't really their issue, but it definitely bumped up the overall cost. The medium size I ordered feels way too snug, especially around the leg openings. Even after just a year of use, they're already falling apart. They don't absorb as well as advertised either. I use them alongside my menstrual cup on heavier days and by myself toward the end of my cycle, but I was expecting better performance. Overall, this was a letdown of a purchase.

Michelle C.Dec 20, 2022

This company is absolutely terrible. I tried to cancel my order right after I realized they misrepresented their sale promotion for leak-resistant underwear. The ad should have said these deals were only on certain styles, but it showed like all pairs qualified. When I didn't get the discount I expected, I attempted to cancel immediately. Their representative told me the order was already in the system and cancellation wasn't possible at that time on a Sunday night. I knew nobody was there to process anything, but apparently I was stuck. Now they're refusing to give me my money back. This is honestly the most unethical and dishonest business I've ever encountered. Please don't order from them.

Monica L.Aug 7, 2022

That advertisement you're running with the woman who's been using the product for thirty-five years is honestly one of the most offensive commercials I've ever seen. It's completely turned me off your brand, and I'm going to make sure other people know how I feel about it.

Jennifer A.Jun 4, 2022

They keep sending me marketing emails even though I placed an order more than five years ago and unsubscribed from their newsletter multiple times. Plus, I think there are tons of better options available nowadays in terms of how long they last, variety of styles, and how sustainable they are.

Sophia M.Nov 4, 2021

You'll feel pretty great about ditching regular pads and tampons when you first get these. But fast forward a few months and you'll be leaking within thirty minutes of wearing them. It's wild how much money they throw at advertising and messaging about women's freedom during their periods, but the only freedom I felt was tossing them in the garbage. If you're hoping to find an eco-friendly long-term solution for managing your period, I'd seriously suggest looking elsewhere. These just don't work. The mess and stress of constantly ruining clothes, bedding, and furniture isn't worth it.

Ryan T.Oct 17, 2021

This period underwear performs pretty well overall. They ship quickly and the quality is solid. My only real complaint is the price point, which is why I'm giving four stars instead of five.

Christopher L.Aug 9, 2021

Sure, the customs charges to the UK are expensive, I won't deny that. But these are seriously the best underwear I've ever purchased. The comfort, quality, and value for the price point make me incredibly happy. If you have heavy flow, yes, you'll probably need to swap them out partway through your day, which is just how period underwear works. They look great, feel amazing on, and they actually work. Highly recommend giving them a shot.

Thomas D.Aug 9, 2021

Yeah, the customs fees for UK orders are definitely steep, that's for sure. But honestly, these are the best period underwear I've ever owned. Considering the comfort and quality you get for the money, I'm really satisfied. And just to be clear, if you have a heavier flow, yes, you'll need to change them during the day. That's totally normal with any period underwear on the market. Apart from that, I absolutely love how they look, how they feel, and how well they do the job. I'd definitely recommend them.

Marcus T.Mar 25, 2021

I've been ordering from this company for quite some time, but my last purchase came with a shock. The customs fee that showed up was way more than I expected, and Thinx really should make this much clearer upfront. While I do appreciate the quality of the underwear itself, the unexpected charge makes it just not worth the money anymore. There are plenty of other brands out there now that offer similar quality at much better prices, so I'm switching.

Rebecca H.Feb 26, 2021

When I placed my order on their UK site, everything showed up in pounds sterling, including the total. But right when I went to pay, it switched to dollars. Plus there was a currency conversion fee on my card, so I reached out to them about it. Their customer service told me I should've known about a customs fee because they mention it at checkout and on their site, and they actually used a sarcastic exclamation mark! I sent them screenshots of every single checkout page showing there's zero warning about customs, whether I used the phone site or Apple Pay, but they just kept insisting I missed it. They did show me screenshots from their US site that has the warnings, but they refused to admit those warnings weren't there for me. At least they offered me a refund, which I'm still waiting on. I never actually got the underwear to test them out.

Lauren P.Jan 11, 2021

The customs charges really turned me off from coming back. I had absolutely no heads up that I'd be charged extra for customs, which honestly feels shady. On top of that, the prices are already pretty high to begin with.
