Easy to use
You can wear Thinx on its own without any additional period products — it’s that absorbent! Or, you can use leakproof period underwear as a backup to tampons or menstrual cups. Thinx offers the look and feel of regular underwear, providing comfort and security throughout your day. Plus, they are machine washable, simply throw them in with the rest of your clothes and line dry. Easy peasy.
What Our Customers Have to Say
My flow used to be medium until I got my non-hormonal copper IUD. A side affect is much heavier periods so i was a little skeptical at first to try these but i am so glad that i did. I wanted to switch to more environmentally friendly period products,
but having an IUD prevents me from being able to use a menstrual cup (the suction might dislodge it). These work perfect for overnight or on your heaviest days. I used to have to change a maxipad multiple times a day or have it leak overnight- but now I dont even have to use a back up method with these!!! (They are pretty thin too). Thank you Thinx for making such an effective and amazing product! I love the message this company is spreading and the strong leaders they partner with. I ordered 5 pairs of the super ones and have 7 other types coming in soon :))

Great for heavy flow from Copper IUD
I was pretty happuy because they have way better coverage in the back than any pad so I was able to wear them to bed without leaking out the back…But then I rolled over and almost instantly leaked out over the front seam because the absorbant section doesnt extend
any further in the front than it does on the regular hip huggers.I’d love them for sleeping in if the absorbant bit just extended a bit more in the front.

Better than a pad…But…
My hip is 36.5 inch, I bought medium because I have a bigger butt. It’s better fitting over the butt area than the sport. It has more seems inside the panty than the sport ones. I have a heavy flow that I leak onto my sheets so bad with
a pad I need to change them in the night. Well I no longer need to change my sheets because the super hip huggers work and catch my flow.
