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.

One could argue that breathability and dryness are even MORE important when it comes to thongs (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 because they’re grown without any poisonous pesticides or herbicides (traces of which can end up in the fabric of your clothing and underwear).

In addition to the type of fabric, it’s also helpful to look for third-party certifications such as GOTS Organic and OEKO-TEX (which indicates the product has been tested for toxic substances). These types of labels 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, now that we know the basics of healthy thong-wearing, let’s get to our list of the BEST ORGANIC COTTON THONG BRANDS!
