Weekly Tip 70: Make a Sustainable Splash

It’s officially summertime, so it’s time to get out your swimsuit. But first, maybe take a moment to consider the impact it’s having on the environment.


Modern-day swimwear faces the same challenges as most fashion nowadays: it’s not built to last. ‘Fast fashion’ is a serious issue, using up energy and resources and causing vast amounts of waste. The main problem with swimwear, however, is that it’s usually made of plastic.


Synthetic fabrics like nylon, polyester, and spandex are perfect for wearing in the water because they wick moisture and stretch across the body. They’re versatile and, most importantly, inexpensive, making them the preferred choice in the fashion industry not just for swimsuits but active- and outerwear too.


Because of this, an estimated 65 million tonnes of these plastic-based materials are generated every year. Plastic isn’t biodegradable, so it sits around in landfills or oceans forever, adding to the estimated 8 billion tonnes of plastic that already exist on the planet. Some countries have even resorted to burning it, which creates enormous amounts of carbon since plastic is made from fossil fuels.


It’s not just the waste that is harmful, though. When we wash synthetic materials, it can release microplastic into the water. These eventually find their way into the ocean, into sea life, and eventually into our own bodies. While the exact effects of these microplastics are still being researched, it’s likely putting stress on our livers and kidneys.


So, what’s the alternative?

Be The Climate Solution

The planet needs your help. Join the movement of people making an impact by reducing your footprint, planting trees, and giving back to the cause that means most to you.

There isn’t currently a biodegradable material with all the performance qualities necessary for a swimsuit. Yet, that hasn’t stopped some pioneering brands from finding new and innovative ways to create swimsuits that are kinder to the environment, from repurposed old fishing nets or even ocean waste.


If you’re on the lookout for some new swimwear, here are some things you can look out for to make sure you’re buying sustainably.

Avoid Virgin Plastic

Considering how much plastic already exists, avoiding swimwear made from virgin (new) nylon and polyester is best. An increasing number of brands are adopting recycled alternatives such as Econyl, regenerated nylon that’s collected from landfill and our oceans instead.

Opt for Natural Fibres

As recycled nylon still releases microplastics when washed, some brands have also started using natural textiles. This can be hemp or Yulex, for example, a natural rubber alternative to petroleum-based neoprene.

Choose Something Durable

Buying swimwear that will last, rather than something you’ll wear for one summer and then throw away, is vital to reducing your environmental footprint. That means looking for durable pieces that will stand the test of time and avoiding flimsy fabrics that quickly lose their shape.

Check for Recycling Schemes

When your swimwear does eventually reach the end of its life, there is a way you can make sure it doesn’t end up in a landfill. Check whether the brand you’re buying from has a recycling scheme and give a new purpose to your swimsuit.


Hand-washing, while only relevant after you’ve bought your swimwear, can still significantly reduce the product’s environmental impact. This stops microplastics from entering waterways and the ocean. It’s also recommended to avoid direct sunlight when hanging them up to dry, which causes the material to thin and the colour to fade.
