SKL top picks, in a nutshell…

Best Plastic-Free Bras for Allergy-Free Comfort 

Ever worn a polyester bra and ended up itching like crazy? Been there, done that! I have a polyester allergy, and my skin breaks out in hives pretty regularly. That’s what drove me to find the best organic activewear brands and plastic-free bra brands on the eco market. And unfortunately, I’m not alone – it’s actually pretty common.  

According to doctors, you’re more likely to get textile dermatitis from clothes made with synthetics such as polyester, rayon, nylon, spandex, or rubber. If you didn’t know, polyester is a plastic derived from petroleum – the same stuff we use to make gasoline.

In addition to being extremely harmful to the skin, The production process of polyester fabric uses a lot of energy and water and releases pollutants. Plus, every time you wash polyester fabrics, they shed tiny plastic particles called microplastics. These microplastics end up in our waterways through our washing machines, affecting marine life and even getting into our food.

So, what can we do? Start by choosing chemical-free bras and undies made from natural, plastic-free materials like organic cotton, Tencel, or bamboo. Not only are these materials kinder to your skin, but they’re also much better for the environment. And trust me, once you make the switch, you’ll never want to go back.

The Environmental Impact of Underwear 

It’s no secret that the fashion industry, including the production of underwear, contributes significantly to global waste generation.

According to the Ellen MacArthur Foundation, the equivalent of one garbage truck of textiles is wasted every second globally, and underwear contributes to this waste stream. When underwear reaches the end of its life cycle, it often ends up in landfills, contributing to environmental pollution.

Unlike plastic-free bras, bralettes, and undies, the production of conventional underwear involves the use of various chemicals in fiber production, dyeing, and finishing processes. These chemicals can have harmful effects on human health and the environment.

For example, synthetic fibers like polyester and nylon are derived from petroleum-based chemicals and may release harmful pollutants during manufacturing. Additionally, the dyes and finishing agents used in underwear production can contain toxic substances that pose risks to both workers and ecosystems.

If that wasn’t bad enough, synthetic fibers used in underwear, shed microplastics during washing. These microplastics are tiny particles that can easily enter waterways and oceans, posing risks to marine life and ecosystems.

A study published in the journal Environmental Science & Technology found that a single synthetic garment can release thousands of microplastic fibers in a single wash cycle.

That’s why it’s so important to opt for chemical-free bras and undies made of natural materials.

Can Plastic-Free Bras Help With Skin Allergies?

Yes, if you are prone to developing rashes, plastic-free bras are the best option. Natural materials such as organic cotton are free from synthetic chemicals and additives often found in traditional bras made from polyester or nylon.

As a result, they’re much gentler on sensitive skin, reducing the risk of irritation, redness, and itching.

Ever noticed how your skin feels suffocated in certain bras? That’s because synthetic fabrics don’t breathe well, trapping moisture and heat against your skin. This can create the perfect breeding ground for bacteria and fungi, leading to skin irritation and even infections.

Plastic-free bras, on the other hand, are more breathable, allowing air to circulate freely and keeping your skin cool and dry.

How Do I Care for Plastic-Free Underwear?

Plastic-free underwear made from natural fibers like organic cotton should be washed using gentle and natural detergents.  To maintain the quality of your plastic-free undies, consider handwashing them with lukewarm water. If using a washing machine, select the delicate cycle with cold water to prevent shrinkage or damage to the fibers. 

Make sure to steer clear of bleach and fabric softeners when washing your plastic-free underwear. These harsh chemicals can weaken the fabric and irritate sensitive skin. After washing, air dry your underwear by laying them flat or hanging them on a clothesline.

This was your complete guide to plastic-free bras!

We hope this list helped you find a new, super comfy, plastic-free bra to add to your underwear rotation. Unlike polyester-based fabrics, natural, allergy-free bras

Are made from sustainable, biodegradable materials that minimize waste and reduce pollution – so you can feel good about what you’re wearing! What’s more, synthetic bras are notorious for shedding microplastics every time you wash them, which can end up polluting our oceans and harming marine life. 

Plus, they can trap moisture and heat against your skin, creating the perfect breeding ground for bacteria and fungi – yikes! But with chemical-free bras, you get breathable, moisture-wicking fabrics that keep your skin cool, dry, and oh-so-happy with zero microplastics.
