A lot of fabrics are not only made of plastic, but they’re also almost always treated with chemicals that can have negative health effects.

Buying natural, organic, and toxin-free clothing is almost always a good idea, but it’s perhaps never more important than when it comes to the fabric that’s right up against your privates all day!

So in this article, we’re going to talk about why fabric choice matters for vaginal health and why organic underwear is the best choice. Then we’ll give you the best organic cotton underwear brands that you can feel good about wearing all day, every day.

Why Organic Cotton Is Better For Health

Conventional cotton is grown using herbicides and pesticides. Although it’s unclear whether or not (and how much) of this pesticide residue ends up in the final product, people who want to play it safe prefer to stick with organic materials when they can.

It’s not just about the pesticides, though. Brands that use organic fabrics for their products are also more likely to use other non-toxic ingredients, such as plant-based and/or azo-free dyes. They are also less likely to contain toxic PFAS.

Not to mention, organic cotton also requires significantly less water to grow, doesn’t strip our topsoil of vital nutrients, and is just better for our environment overall.

What Does Breathability In Underwear Mean?

Some types of fabrics allow moisture to flow through them, keeping the fabric drier as a result. Other types of fabrics keep moisture trapped. Cotton is generally more breathable than synthetics like nylon or polyester.

Breathability means more airflow. It means that moisture won’t get trapped in the fabric of your underwear, which means you won’t have to worry as much about sticky, sweaty environments that are more conducive to bacterial and yeast infections as well as skin irritation and chafing.

Is ‘Made in the USA’ Better Than ‘Made in China’ (or Elsewhere)?

It’s an easy assumption to make that ‘Made in the USA’ automatically means the product is better than if it’s made somewhere else. If something is Made in the USA, that means it’s of higher-quality, right? It means it’s made ethically and not in a sweatshop, right?

Not necessarily.

As a US-resident, there are plenty of reasons why you might want to buy goods that are made in the USA. There’s a lower carbon footprint because there’s usually less shipping the product around the world. Also, buying US-made products contributes to the local economy and keeps manufacturing jobs in the States.

BUT, there are also plenty of factories around the globe that prioritize quality, transparency, and ethics. AND although generally, worker rights and labor regulations are stricter and more tightly monitored in the U.S. compared to other countries in the global south, ‘Made in the USA’ does not always equal ‘ethical’ or ‘sweatshop-free.’ (Yes, there are sweatshops in Los Angeles.)

That’s just something to keep in mind as you shop around and choose which brands are best for you. All that being said, the brands below are all made ethically in the USA out of (mostly) organic cotton!

How Often Are You Supposed to Get New Underwear?

Because of how bacteria that doesn’t always fully come out in the laundry, some gynecologists recommend that you swap out your underwear every 6 to 12 months(!). For many people, that’s a lot!

But other doctors disagree, saying that as long as you’re washing your underwear regularly (after each wear), then you can be safe to keep your underwear for as long as it’s not falling apart, saving you a lot of money and waste!

After all, not all bacteria is bad. Just like our gut microbiomes, vaginas have a microbiome as well. A healthy one is maintained through a balance of “good” and “bad” bacteria.

If you really want to give your laundry an extra boost to make sure you’re keeping your underwear as clean as possible, you can use an additive such as Branch Basics oxygen boost.

And when you are ready to do a top drawer swap, there are some underwear brands like Knickey that have recycling programs. Instead of throwing your old undies into the trash, you can send them in where they will be sanitized and recycled into something new, like carpet padding.

To Wear Or Not To Wear: Going Commando

In order to increase breathability even more, it’s good to sleep without underwear if you can!
