The Best Sustainable Swimwear Brands to Support This Summer

When it comes to building a more conscious and sustainable wardrobe, we shouldn’t forget about our bathing suit collection. Conventional swimwear is made with virgin nylon and polyester, both of which are forms of plastic that have a massively negative environmental impact and contribute to microplastics and ocean waste. In addition to this, we should also remember that fast fashion brands and large corporations often use unethical labour to create cheaper and lower-quality clothing.

Luckily, there are more than a handful of eco-friendly swimwear brands out there today that are aiming to make a difference when it comes to our holiday attire. Several sustainable brands are dedicated to lowering their carbon footprint, providing workers with good working conditions, and using sustainable fabrics and recycled materials like recycled polyester, nylon, and plastic bottles.

Interested in supporting sustainable and ethical swimwear brands that are creating eco-friendly swimwear? Here are just a few of our favourites you should add to your swimsuit collection.
