In need of some eco-friendly support? Try our guide to the best sustainable sports bras made from recycled or organic fabrics, from brands that we say bra-vo to.
Nylon, lycra, polyester and other stretchy fabrics may perform well in the gym or on a run or bike ride. Yet there’s a downside. These performance fabrics tend to be made from virgin plastics, which are derived from planet-warming fossil fuels. As such, your sports gear can have a pretty hefty carbon footprint.
The good news is that greener alternatives are now available for all your activewear needs. If, in particular, you are looking for a sustainable sports bra that helps you to stay comfortable and perform, but also has a positive impact on the environment then I’ve got you covered.
From the brands using recycled or natural fabrics, you’ll find out how the latest innovators are revolutionising the industry with their sustainable solutions. This helps to give you the support you need whilst supporting the health of the planet.

⭐ Best for sustainable sports bras made from natural fibres
Caters for: UK sizes 8 – 22
Available from: Modibodi
Sports bras aren’t often made from natural fibres. However, this one, from Modibodi is made from 95% Merino wool. This wool is then sourced from mulesing-free farms.
There’s a little bit of elastane for stretch and it is lined with recycled nylon. This means if you are looking to avoid synthetic fibres completely then do look for an alternative.
What we love about this sustainable sports bra is that the soft Merino wool helps to regulate your temperature while you work out and control odour. It also cleverly features an invisible zip pocket, perfect for your keys or coins.
Suitable for light-impact workouts, removable foam bra cups are included for extra support.
Modibodi’s supply chain partners are audited under BSCI standards. This ensures fair working pay, reasonable hours, and safe working conditions.
Meanwhile, through its charitable Give A Pair programme, every pound donated by customers goes towards providing someone in need with a pack of five pairs of period undies. So far, it has donated more than 125,000 pairs of pants to people in need through its charity partners. These partners include Bloody Good Period and Plan International.
