What To Look for in Non-Toxic, Organic Thong Underwear
Just like we talked about with regular organic cotton underwear, the type of fabric your panties are made of is important for vaginal health. Gynecologists recommend a natural material like cotton because it’s breathable, moisture-wicking, and free from the potentially toxic chemicals that often come with synthetics like polyester.
One could argue that breathability and dryness are even MORE important when it comes to thongs (even compared to full-bottomed brief underwear) because of the way thongs can contribute to potential infection.
Not only that, but organically-grown natural fibers such as cotton and hemp are even better than conventional cotton because they’re grown without any toxic pesticides or herbicides.
In addition to the type of fabric, it’s also helpful to look for third-party certifications such as GOTS Organic and OEKO-TEX. These types of labels are not perfect, but they do indicate that the product has been held to a specific set of standards set by an outside organization.
Good Thong Habits for Health
We’ll just get out with it: wearing thongs and g-strings can move bacteria from your back to your front, which can cause or contribute to infections. For this reason, it’s important to have good thong-wearing practices as well as great hygiene when wearing this type of panty.
For most people, wearing thongs with certain outfits and/or for limited periods of time is totally fine. But wearing them daily, working out in them regularly, sleeping in them, and/or wearing them with fabrics that are not breathable may not be the best ideas, according to gynecologists. So if you’re having problems down there, you may want to try not wearing thongs for a while and/or changing out of your thong more frequently.
These Are the Brands Making the Best Organic Thongs in 2023:
So, now that we know the basics of healthy thong-wearing, let’s get to our list of the the best organic cotton thong brands:
If you’ve spent very much time shopping for organic underwear, you’ve probably come across Pact. They are one of the most well-known brands for Fair Trade organic cotton undies for a reason!
Not only is their underwear (which they make for women, men, and kids) super comfortable, but Pact was one of the very first brands on the scene to offer truly affordable organic undergarments.
They carry a wide variety of patterns and styles, from their standard Thong to their comfortable Waist-Lace Thongs.
Everything comes with GOTS Organic and Fair Trade certifications.
For my review: I’ve been wearing Pact’s underwear for years now. They’re easy to wear under a variety of different kinds of pants—jeans, leggings, etc. I like how they offer a lot of different patterns, too. So you can go with a basic solid or you can switch it up with something fun if you feel like it.

Knickey makes super comfortable undies available in a variety of styles (including low-rise and high-rise thongs), sizes, and colors (including naturals and cold solids). Everything is made out of 95% GOTS certified organic cotton with 5% elastane for stretch.
They’re free of things like toxic dyes and come with certifications like OEKO-TEX and Fair Trade International. Knickey is also a great brand for plus-size thong underwear.
I’ve been wearing Knickey’s underwear ever since they launched! Their construction has gotten even better since they first started. My high-rise Knickey thong is honestly one of my favorite pairs of underwear. They’re so comfortable to wear under any high-rise pants.

This Australian-based brand carries several different organic cotton thong variations, from cheeky cut, to V-string, to G-string. They’re ethically made using GOTS certified organic cotton and non-toxic, eco-friendly dyes.
I really love my Le Buns undies. The fabric is stretchy enough to be comfortable, but it also feels a bit thicker than other brands, so I feel more supported when I wear it. It also holds its shape really well so it’s still fitting the same way at the end of the day.
Price Range: $19 (on sale) – $37
Material breakdown: 90% organic cotton, 10% elastane

Araks is also one of the few brands that offers organic cotton g-strings. They also have silk thongs too for a softer and sexier option.
Note that not all of Araks’ underwear is made from natural fabrics, so make sure to check the details before purchasing.

Plus, Oddobody does a lot of work toward bodily education and autonomy, which is pretty cool.

Organic Basics’ skin-friendly underwear is not only ethically made out of organic cotton (mostly), but it’s also PETA-approved vegan. (Of course, many of the brands here are free from animal products, but not all of them come with third party reassurance.)
They offer a “standard” organic thong, but then they also have a seamless high waist tanga, which is not only super soft but is a good option for working out since it’s seamless and more form-fitting. Plus, it’s got little keyhole touches to give it a pretty feminine look.
They do have an “Active Thong” which is made out of (partially recycled) synthetics like nylon, so make sure to check the materials before buying so that you know what you’re getting.
Price Range: $20-$45 (2-pack)
Material breakdown: 95% organic cotton, 5% elastane OR 85% organic cotton, 10% recycled polyamide, 5% elastane

They also offer a “First Pair Guarantee,” which means that if for any reason you are not happy with your first pair of underwear, they will send you a new size, color, or issue you a refund (no questions asked). This differs from most underwear brands, which don’t offer refunds or returns on undies.
Price Range: $24

The allergy-friendly elastic is free from rubber and latex and is wrapped in the cotton fabric so that none of it touches the skin. It’s sewn with a flat seam to further prevent irritation from bunching or rubbing.
