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.

Sizes: XS-XXL
Price Range: $10 (on sale) – $75 (6-pack)
Material breakdown: 95% organic cotton, 5% elastane

KENT’s thongs are made out of 100% GOTS organic Pima cotton for the utmost breathability and comfort. They’re completely synthetic-free, which means no spandex, elastane, or other plastic materials. They’re all made ethically in California AND they’re completely compostable, too!

Subset (formerly called Knickey) makes super comfortable undies available in a variety of styles (including low-rise and high-rise thongs), sizes, and colors (including natural 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. Subset is also a great brand for plus-size thong underwear.

I’ve been wearing Subset’s underwear ever since they launched! Their construction has gotten even better since they first started. My high-rise Subset thong is honestly one of my favorite pairs of underwear. They’re so comfortable to wear under any high-rise pants.

Sizes: 2XS-3XL
Price Range: $17
Material breakdown: 95% organic cotton, 5% elastane

Le Buns

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.

Sizes: 6-16
Price Range: $19 (on sale) – $37
Material breakdown: 90% organic cotton, 10% elastane

In addition to their briefs, hipsters, and bralettes, Araks carries GOTS certified organic cotton thongs as well. They’re made in the USA and come in a selection of gorgeous colors.

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.

Sizes: XS-XL
Price Range: $30 (on sale) – $55
Material breakdown: 100% organic cotton OR 92% silk, 8% elastane


Oddobody actually doesn’t use anything synthetics in their fabrics — it’s all 100% GOTS certified organic cotton.

They come in several solid colors (black, white, pink, blue, and red) and sizes range from XS to 3XL. They’re made in Fair Trade Certified factories in Peru.

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

Organic Basics

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 variety of different styles and fits, including your “standard” organic thong, high- and low-rise options, stretchy ones, and more.

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.

Sizes: 2XS-2XL
Price Range: $20-$45 (2-pack)
Material breakdown: 95% organic cotton, 5% elastane OR 85% organic cotton, 10% recycled polyamide, 5% elastane


WAMA’s underwear for men and women is made out of sustainable and non-toxic hemp combined with organic cotton and a little bit of spandex for the perfect fit. They come in green or black and you can grab packs of 1, 3, 6, or 10 (and you get a discount if you buy more!).

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.

WAMA’s undies are made in Vietnam in a WRAP certified factory.

Sizes: XS-4XL
Price Range: $24
Material breakdown: 53% hemp, 44% organic cotton, 3% spandex


If you have extra sensitive skin, eczema, or a similar condition, you may want to try out Cottonique. Their entire hypoallergenic collection is specifically made for people with sensitivities.

The main fabric used for their thongs is 100% organic cotton, so it’s free from synthetics. 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.

Sizes: XS-XL
Price Range: $30 (2-pack)
Material breakdown: 100% organic cotton

Tentree’s “Everyday Thong” is made using a combination of plant-based TENCEL, organic cotton, and elastane for ultimate softness and comfort. TENCEL is a great semi-synthetic that offers a softer feel than cotton typically gives.

Great for everyday wearing, these undies come in a few basic solid colors and are ethically made in Turkey.

Their Mid-Rise Thong is available in classic colors like “Onyx” (black) and “Sand” (beige), and their Low-Rise Thong comes in a couple of fun colors like “Sunflower” (yellow) and “Olive” (green).

Some of their options have dainty little trims for a feminine touch.

Ethically made in Bali, these undies come with a handful of third-party certifications, including Global Organic Textile Standard (GOTS) and Zero Waste Packaging.

Price Range: $21-$34
Material breakdown: 90-95% organic cotton 5-10% elastane
