In recent years, the global movement towards sustainable living has gained significant momentum. As consumers become more conscious of the environmental impact of their choices, they are seeking out eco-friendly alternatives in various aspects of their lives. One such area that is undergoing a positive transformation in the fashion industry, often named as slow fashion (as opposed to fast fashion which is typical of a linear society), is plastic-free underwear. In this article, we will explore the importance of non plastic underwear, its benefits, and the brands leading the way in creating stylish and sustainable undergarments that non only feel good on your skin, but are also good for the planet!
Many people may not realize that traditional underwear, like traditional hosiery, is often made from synthetic fabrics, such as nylon and polyester, which are derived from petroleum-based plastics. These materials not only contribute to the growing plastic pollution crisis but also have a significant carbon footprint due to their energy-intensive production processes. Moreover, these synthetic fabrics are non-biodegradable, meaning they persist in the environment for hundreds of years when discarded, releasing microplastics that harm marine wildlife and contaminate ecosystems.
It’s easy to recycle shoes, clothing, accessories, but what about underwear?
The only end for this type of garment is landfill, recycling, or composting (if all fibers are of organic origin). In fact, around 11 million pounds of underwear end up in a landfill every single day. This is very alarming and it is one of the reasons why eco-friendly organic underwear is on the rise.
Furthermore, there’s another aspect that needs to be clarified. Before they end up in landfill, we need to think about their environmental impact while in life. For an average wash load of 6 kg of synthetic fibers, over 700,000 microplastic fibers could be released per wash into our oceans through the washing machine. This environmental issue is even more concerning!

According to a 2003 Italian study published in the European Journal of Obstetrics & Gynecology and Reproductive Biology that looked into underwear and health, one of the factors associated with vaginal yeast infections was wearing synthetic fabric underwear, because it doesn’t allow our skin to ‘breathe’ and thus keeps the genital area warm and moist, which are perfect conditions for the growth of yeast and infections.
Have you ever noticed that synthetic fibers easily smell?
This is because bacteria that cause body odor grow better on synthetic fibers like polyster for example. It’s, therefore, very important to wear breathable underwear, aka underwear made of natural fibers, even more if you live in a hot and humid climate like the tropics.
Recent research from The Center for Environmental Health (CEH) in the USA revealed high levels of BPA in sports bras, athletic shirts and even in polyester-based clothing with spandex, including socks made for infants. BPA is a well-studied hormone disrupting chemical, which mimics estrogen and can disrupt the normal functioning of the body, including metabolism, growth and development, and reproduction.
The CEH research centre, which conducted the tests and is a non-profit consumer advocacy group focused on exposing the presence of toxic chemicals in consumer products, found those sports bras could expose wearers to up to 22 times the safe limit of BPA, based on standards set under California law — specifically Proposition 65, enacted in 1986 — that the maximum allowable dose level for BPA via skin exposure is 3 micrograms per day. Throughout 2021, CEH has pushed more than 90 companies to reformulate their products to remove all bisphenols including BPA, and some have already agreed to do so. It’s no wonder that more and more people are now searching for BPA free organic sports bras.
By choosing plastic-free underwear, consumers can actively contribute to reducing plastic waste and its detrimental impact on the environment. Plastic-free alternatives are made from natural, biodegradable materials that break down over time, leaving no lasting harm. Look also for plastic-free period underwear or plastic-free panty liners if you want to reduce your plastic waste footprint.
Polyester-free underwear often utilizes organic fabrics like cotton, bamboo, hemp, lyocell or modal, which are known for their breathability and softness. These materials allow air circulation, preventing sweat buildup and enhancing overall comfort.
Natural fibers used in plastic-free underwear are hypoallergenic and gentle on the skin. They reduce the risk of irritation, rashes, and allergies that can be caused by synthetic fabrics and chemical dyes commonly found in conventional underwear. You can also find latex free underwear if you are allergic to this material.
Plastic-free underwear brands are committed to sustainable production practices. They prioritize fair trade, ethical sourcing, and use eco-friendly manufacturing techniques, reducing their carbon footprint and supporting responsible supply chains.

In 2023 they launched the Next Gen sustainable sports bra on Kickstarter and it was an immediate success.

It’s highly breathable for extra skin confort and suitable for people with skin allergies as it doesn’t itch when you sweat.

Compostability: please note that the products include some elastane in them which is why they are not compostable.
