best sustainable swimwear brands

It used to be a struggle to find eco-friendly and ethical swimwear that was also stylish and high-quality. However, these days there are plenty of sustainable swimwear brands making stunning pieces – here are our some of the best sustainable swimwear brands on the market today!

Why is sustainability in fashion important?

As consumers have demanded increasingly cheaper clothing, swimwear, and accessories over the years, the fashion industry has responded by slashing prices. We can now buy items at a fraction of the comparative cost 20 or 30 years ago, so it’s possible to virtually purchase a new wardrobe every season.

However, this has come at a hidden cost: making production faster and cheaper involves practices that are damaging to people and the planet at all stages of production.

Firstly, the global fashion industry is a major contributor to greenhouse gasses. The majority of fabrics used these days to make clothing and swimwear – such as polyester, nylon, spandex, and lycra – are derived from fossil fuels and petroleum-based compounds.

Extracting fossil fuels is very environmentally destructive, and processing them into fabrics generates large amounts of emissions.

The clothing industry produces large amounts of low-quality items that don’t last long

Another problem with fast fashion is the volumes involved: the industry creates huge amounts of clothing that is not designed to last, and consumers buy large numbers of items and then throw them away after just a few wears. At the end of the product life cycle, this means sending a tremendous amount of waste to landfill (though you can recycle clothing).

At the start of the process, producing so much fast fashion represents an incredible drain on the earth’s resources. A staggering 97% of materials used to make clothing are new resources and only 3% are recycled.

The resources used to make clothing and swimwear include oil, fertilizers, and chemicals used to produce the finished fabric, the runoff from which can also cause soil and water pollution. Incredible amounts of water – an increasingly scarce resource globally – are used to grow crops like cotton as well make the final products. The best sustainable swimwear brands will avoid using such resources.

Fast fashion is not only devastating to the natural environment, but it can also have terrible impacts on the people involved in the supply chain. The modern fashion industry too often involves unfair wages, terrible working conditions and exploitation of the workers who grow raw materials, produce fabrics and make garments.

What are the best sustainable swimwear brands to shop for?

The best sustainable swimwear brands aim to minimize their use of natural resources, use recycled materials, and use ethical and environmentally-responsible processes, from how the raw materials are grown, through fabric creation to making the final product. For example, organic cotton uses nearly 91% less water than conventional cotton.

Furthermore, sustainable fashion is all about producing high-quality items that will last for years, so you don’t need to replace them so often.
