organic sports bras

It’s safe to say that nothing can ruin our workout mood quite like an ill-fitting sports bra.

Whether it digs into your skin, keeps pulling up, or simply can’t support your high-impact workouts, it’s extremely distracting and aggravating. Plus, unlike the best organic sports bras of 2024, regular options can very well cause some rashes and skin irritation around the breasts or the back.

These reddish, cracked, and itchy rashes go hand in hand with synthetic, toxic-chemical-packed fabrics – especially when sweating is involved.

But don’t worry! Our list of sustainable non toxic sports bras will make the perfect addition to your workout wardrobe. From the best organic cotton sports bras to bamboo sports bras and hemp options, here are the most noteworthy styles of 2024.

Are there toxic chemicals in sports bras?

Yes, unfortunately, there are many toxic materials in sports bras! For instance, some synthetic styles are made with typical sports bra materials that are treated with nasty chemicals like formaldehyde, which can cause skin irritation and allergic reactions. Additionally, some sports bras may also contain harmful dyes and finishes, such as chlorine bleach, that can cause skin irritation and have negative environmental impacts.

Let’s not forget flame radiants which have been found to be harmful to human health, particularly when they are inhaled or absorbed through the skin. These chemicals can disrupt hormones, cause cancer, and affect the reproductive and nervous systems.

Some studies have also shown that they can accumulate in the body over time. To avoid these toxic materials, it’s best to choose organic sports bras made from natural materials like cotton, hemp, and bamboo.

What is the healthiest material for sports bras?

The healthiest materials for sports bras are organic cotton, hemp, bamboo, Tencel lyocell, and even recycled polyester. These materials are breathable, moisture-wicking, and free from harmful chemicals, making them a great choice for those with sensitive skin or concerned about their health and the environment.

Who makes the safest yet most supportive sports bra?

Julie May, Patagonia, Ice Breaker, Wama, TomBoyX, Organic Basics, Boody, Girlfriend Collective, and PACT make the safest and most supportive organic sports bras on the eco market. All you have to do is have a look at the hundreds of raving reviews from satisfied fitness enthusiasts.

This post is about the best natural sports bras.
