nyone who’s had to survive a day in lousy underwear knows just how important it is to choose wisely. Underwear can affect how our clothes fit and how confident we feel, and depending on how they’re made, it can also impact our health and even more significant environmental issues.
In this article, we’re going to get intimately acquainted with the world of non-toxic, eco-friendly, and ethical underwear. We’ll look at why it’s worth being more mindful of the undergarments you wear, how to choose items that last, and 17 of the best brands to shop with for your next fresh pair.

What is ethical underwear?
“Ethical” underwear is all about paying more attention to how they’re made, especially from a labor perspective. This includes:
- Fair wage practices.
- Safe factory conditions.
- Transparency regarding both of the above, as well as general production methods.
That last point is the most important. No underwear brand can truly call itself ethical unless it’s willing to be open with customers about where their garments are being made and under what conditions. Bigger companies can afford to take this a step further with outside audits and certifications, such as being a B Corp, but any amount of transparency should be celebrated.
Small, local businesses are often an excellent source for more ethical underwear, as production is usually more hands-on. Those making their products in countries or states with strict labor laws are also worth looking out for, as this helps ensure that your underwear was made under more ethical conditions.
What is eco-friendly underwear?

The world of eco-friendly underwear covers more traditional questions of sustainability, such as the environmental impact of the garments. When you’re shopping for eco-friendly underwear, it’s best to consider these main factors:
Check the fabric label
As with any clothing item, the material your underwear is made from hugely determines its environmental impact. To get a better sense of this, let’s break down the impact of two of the most common synthetic materials you’ll find in underwear:
- Nylon: Not only is nylon not biodegradable, but the production of this fiber is energy-intensive and creates nitrous oxide, which is 300 times more potent than carbon dioxide.
- Elastane: This is another energy-intensive, non-biodegradable fabric with the added downside of petrochemicals being used in the production process.
As much as both these fabrics contribute to pollution issues, avoiding them isn’t altogether easy or necessary. Both are extremely useful for underwear because of how lightweight and stretchy they are. The use of some elastane can also improve underwear longevity as it helps the garment “snap back” into shape after wear. To limit environmental impact, more eco-friendly underwear brands will try to use recycled nylon or elastane where possible and generally limit their use to where necessary.
Sustainable underwear will stick to natural, biodegradable fabrics as much as they can. Even within that, however, there are things to check for on the fabric label, such as:
- Organic materials: GOTS-certified cotton or organically sourced bamboo fibers are two excellent materials to look for when shopping for sustainable underwear, as they mean less water and agrochemicals were used to produce the fabrics.
- Recycled or Re-Purposed Fibers: About 97 million tons of textile waste go to landfills each year. That’s why a big part of buying more eco-friendly underwear is supporting brands that use recycled materials or re-purposed deadstock.
Unfortunately, making any kind of fabric involves energy and chemicals. There’s no perfect option, but there are better ones, like brands that stick to organic materials or only use recycled nylon. Every bit counts.
Carbon footprint and energy use
Beyond the materials used, making underwear in factories and eventually shipping those items invariably uses a lot of energy and adds to the final carbon footprint.
Here’s what to look out for in this area when shopping for more eco-friendly underwear:
- Efforts to reduce water and non-renewable energy usage in their factories, etc.
- A carbon-neutral program.
- Sticking to recyclable packaging.
This helps limit the negative impact that may come from the production of the garments, which helps keep our planet a little healthier.
Underwear lifespan and longevity
Even the most sustainably made underwear will eventually reach the end of its life and need to be discarded. The best eco-friendly underwear brands run recycling programs to ensure the fabric doesn’t go to landfills. It’s also important that items are well-made and have decent longevity. The longer your underwear lasts, the less frequently you’ll need to buy new pairs, which helps limit how much goes to waste.
Our criteria for non-toxic underwear (and why it matters)
![Woman wearing burnt orange colored panties with flowers lining the outsides symbolizing non-toxic underwear.](https://cdn.prod.website-files.com/644bdafbe0ef561dd4055717/66d15d823acca30dfe225f11_668716d7b03f246b7d2b951b_AdobeStock_520683544.jpeg)
Have you ever noticed that certain underwear rubs you the wrong way or makes you feel a bit sweaty within hours of putting it on? Sometimes, it’s because the fit is bad, but it may also be due to less-than-desirable fabrics.
Here are the three main factors that we use to define non-toxic underwear and why they matter for your health and comfort:
- They are made from predominantly natural and organic fibers. Natural fibers tend to be the most breathable – a highly important factor for vaginal health. Breathability allows the area to stay dry, reducing the risk of bacterial growth and issues like yeast infections. Organic materials further minimize exposure to potentially harmful chemicals such as pesticides. Natural and organic materials are also less likely to cause allergic reactions in sensitive areas, as they’re softer and have fewer irritants.
- Features non-toxic dyes: Another source of skin-irritating chemicals is the dyes used in underwear. That’s why we think non-toxic underwear should use natural or OEKO-TEX-certified dyes.
- No nylon or synthetic fabrics are used in the gusset: The gusset is the area of your underwear that directly covers your genitals and should always be made from natural fiber. Again, it’s a matter of breathability, but it’s also worth noting that synthetics like nylon can leach BPAs and other harmful chemicals, which should not be near sensitive parts.
Ultimately, the most critical aspect of non-toxic underwear is that it limits wearers’ exposure to potentially toxic chemicals wherever possible. That way, you can reduce associated health risks and the chance of discomfort.
How to choose underwear that lasts
![A store filled with different kinds of underwear to shop from.](https://cdn.prod.website-files.com/644bdafbe0ef561dd4055717/66d15d823acca30dfe225f2e_668716f98135ea4b9f603e43_AdobeStock_642499125.jpeg)
There’s nothing worse than wearing underwear just once, only to find that either they’re horribly uncomfortable or that the elastic has already given out. Here’s how to make sure you only buy underwear that lasts.
- Try to stick to styles that you know complement your needs. For example, seam-free underwear should be worn if it’s essential that lines are not shown. This will ensure you get the wear out of your purchases and avoid creating unnecessary waste. Make sure to also stick to fits you know you like and that work on your body.
- Check reviews. Even if you’re shopping in-store, it’s worth taking a second to check out online reviews of a brand to see what other customers are saying about how well the underwear has lasted.
- Consider the fabric. High-quality organic cotton and bamboo, for example, tend to be very long-lasting. Stick to natural fibers where possible, but a blend with small amounts of elastane or nylon can also help strengthen the material.
How often should you replace your underwear?
According to this article, in which multiple OB-GYNs weigh in on the topic, as long as you’re washing your underwear properly, you need only replace it when it becomes uncomfortable to wear. Just make sure you’re using soap and warm water to wash it after each use, and there shouldn’t be any need for concern. That said, if it starts to lose its shape or the waistband gives out, it’s likely time to retire it.
