The Best Non Toxic Sports Bras for a Healthier Workout
It seems like a no brainer, right? Staying active = good for our health. Well, for the most part, yes. But here’s the kicker: Unless your rocking non toxic sports bras, you could be counteracting a lot of that good!
Sure, working out is great for our body and mind, but if we're wearing gear loaded with nasty chemicals, we're not really doing ourselves any favors.
In this article, we'll get into nontoxic sports bras and how they can genuinely support our health. Plus, we'll break down what makes those regular sports bras not-so-great. And because we love finding the best options for non toxic living, we’ve rounded up our top picks for non-toxic alternatives to keep us comfy and chemical-free.
Why Switch to Non Toxic Sports Bras?
Conventional sports bras may look good on those toned bods, but they often come with hidden risks—synthetic fabrics and chemicals that can irritate your skin and expose you to toxins. That is definitely not sexy. Here’s why making the switch to non-toxic options is worth it:
Hidden BPA Dangers: Did you know that some sports bras can expose you to up to 40 times the safe limit of BPA? This chemical, often found in plastic water bottles, can also lurk in synthetic sports bras, leading to potential hormone disruption .
Pesticides in Fabrics: Non-organic fabrics, particularly cotton, are often treated with pesticides. In fact, seven of the 15 pesticides commonly used on cotton in the U.S. are listed as “probable” or “known” human carcinogens by the EPA .
PFAS and Forever Chemicals: Many synthetic sports bras are treated with PFAS (per- and polyfluoroalkyl substances) to make them moisture-resistant. These “forever chemicals” don’t break down in the environment and have been linked to immune system suppression, increased cholesterol levels, and even certain cancers.
Microplastics in Your Laundry: Washing synthetic fabrics, including many conventional sports bras, can release microplastics into our waterways. These tiny plastic particles are not only harmful to marine life but can also make their way back into our food and water supply.
Switching to non-toxic sports bras made from natural fibers or recycled materials means you’re not just protecting your health—you’re also making a choice that’s better for the planet.

How Do We Choose the Best Non Toxic Sports Bras?
We take pride in our selection process to ensure you get the best non-toxic sports bras available. Here’s how we do it:
Our selection process starts with thorough research. We begin by vetting the brands, digging into their sustainability practices, certifications, and the materials they use. From there, we narrow down our list based on customer reviews and expert feedback to identify the top contenders.
Once we have our shortlist, it’s time to put these bras to the test. We wear them ourselves during various workouts—hot yoga, running, HIIT, and even just house loungin'—to see how they hold up in real-life scenarios. This hands-on approach helps us ensure that each bra isn’t just non-toxic but also comfortable and effective.
We’ve carefully curated our recommendations into two categories—"Best" and "Better"
"Best" products are our top picks for non-toxic sports bras. These options are sustainable sports bras made from natural materials like organic cotton and bamboo, which are inherently non-toxic. We’ve chosen these because they offer not only the best in safety but also a comfortable, skin-friendly experience.
"Better" products are still great choices. While they may be made from synthetic fabrics, they meet high standards for sustainability, so we wanted to include them in this list. These are perfect for those who might be okay with a bit of synthetic material as long as the product is created with environmental health in mind.
We know finding the right balance between sustainability and performance can be tricky, so we hope these options help you feel good about your choice, both in and out of the gym.

Sports Bras Are Toxic? Really??
When we think about sports bras, we're usually focused on finding that perfect blend of support and comfort.
But here's something unexpected—many sports bras are hiding some pretty toxic secrets. Those stretchy, durable fabrics like polyester and spandex often come with a side of harmful chemicals, including dyes, formaldehyde, and even the notorious PFAS, also known as “forever chemicals.”
While these materials give us the performance we crave, they also make us wonder, what exactly are we putting next to our skin? And let’s not forget the environmental impact.
It’s a good reminder that our workout gear deserves as much scrutiny as our skincare, and maybe it’s time to consider more sustainable, non-toxic options that love our bodies and the planet back.
PFAS in Sports Bras
PFAS, or “forever chemicals,” are often used in sports bras to make fabrics more durable and moisture-resistant. But the problem is, these chemicals don’t just stay in the fabric.
When we sweat during a workout, PFAS can transfer from our bras to our skin, potentially making their way into our bodies. That’s concerning, given PFAS have been linked to hormone disruption, immune issues, and even certain cancers.
Sports Bras & Nursing Mothers
When it comes to the safety of your baby, every choice matters—especially what you wear close to your skin. Unfortunately, not enough research has been done to determine the safety of wearing clothing that contains PFAS on the breasts while nursing.
These chemicals, often found in water-resistant or stain-resistant fabrics, have been linked to potential health risks, and we believe it’s better to be safe than sorry.
Given the lack of comprehensive testing, we recommend opting for non-toxic, PFAS-free bras and clothing during your nursing journey. This ensures that your baby is only exposed to the safest, most natural materials, allowing you to focus on what matters most—nurturing your little one.
An Environmental Conundrum...
Polyester and nylon are the go-tos for durable and supportive sports bras, but here’s the catch—they take hundreds of years to break down in landfills. That’s a huge environmental issue. Like really HUGE.
Recycled materials, like recycled nylon and those made from PET bottles, offer a better alternative for those of us prioritizing sustainability. However, they can still carry some of the same harmful chemicals.
So, while recycled fabrics are a step in the right direction, we need to be mindful of the trade-offs between sustainability and potential chemical exposure.
Natural Fibers: Organic Cotton, and Bamboo, and Wool, Oh My!
When it comes to sports bras and other athletic clothing like leggings for that matter, organic cotton, bamboo, and merino wool are the real MVPs.
These materials are not only soft and breathable, but they’re also free from harmful chemicals, making them a healthier choice for our skin. Plus, their manufacturing processes are far more sustainable—especially with organic options that avoid toxic pesticides. Regenerative farming practices? That's like organic plus!
Choosing these fabrics means we’re doing good for our bodies and the planet, one workout at a time.
What certifications should I look for in non-toxic sports bras?
GOTS (Global Organic Textile Standard), OEKO-TEX, Fair Trade Certified, and B Corp ensure that sports bras are non-toxic, ethically produced, and environmentally responsible. GOTS ensures the use of organic fibers, OEKO-TEX certifies that the textiles are free from harmful substances, Fair Trade Certified ensures ethical labor practices, and B Corp focuses on social and environmental responsibility.
Key Takeaways:
-
Many conventional sports bras contain synthetic fabrics and chemicals like PFAS, which can pose health risks, especially when they come into contact with sweat. For nursing mothers, this exposure can be particularly concerning.
-
While recycled materials offer a more sustainable option, they still may carry harmful chemicals. Organic cotton, bamboo, and merino wool are healthier alternatives, providing softness, breathability, and reduced chemical exposure.
-
Ready to make a change? Switch to non-toxic sports bras made from natural or recycled materials to protect your health and support sustainable practices. Your choices are making a difference!
