Your Guide to Ethical & Sustainable Swimwear

Your Guide to Ethical & Sustainable Swimwear

Are you looking to hit the beach in a beautiful and ethical swimsuit this year? With lockdown finally easing, it doesn’t matter if you’ll be going on a staycation in your back garden or if you are keen to bite the bullet and travel, an ethical swimsuit is a summer essential. There is something you’ll need to keep in mind however, swimsuits are made of plastic as it’s the plastic fibres that provide elasticity to your suit.

The most popular swimsuit fabrics are polyester and nylon – both of which are made from plastic. And as we know from my previous post about sustainable fashion, the trouble with plastic in clothing is that it sheds microplastic fibres every time it’s washed. But this doesn’t mean that you can never wear a swimsuit again, you can still make smarter choices and take extra care when washing plastic containing clothing items not just your swimwear.

Filtering Microplastics when Washing Swimwear Fabrics

There are two ways to filter out microplastics when you wash items of clothing, the first is using a guppyfriend bag like this. And the second is to invest in this Filtrol, microfibre filter. Both of these are used to stop microplastic fibres to enter the outlet of your washing machine, which means you’ll be able to reduce the damage caused by washing plastic containing fabrics.

I particularly like the Filtrol listed as this is less restrictive and easier to use, you just attach the filter to your washing machine outlet and clean it once it’s filled up. It’s a great timesaver and according to the product’s technical information, it’s really effective.

Sustainable Swimwear Fabric Options

The most common fabric options for sustainable swimwear usually include recycled plastics, they are:

Econyl is made from regenerated nylon and is a very popular choice with sustainable swimwear brands. It’s made from collected waste such as fishing nets, old carpets and industrial plastic from landfill and the ocean. It is recycled back to its original purity, which means it has the same properties as regular nylon. Recycling plastics in this way saves large amounts of crude oil and carbon dioxide equivalent emissions. So besides the microplastic issues during washing, Econyl is a great eco fabric option for ethical swimwear.  

REPREVE is a branded performance fibre made from recycled materials (including plastic bottles). To guarantee the recycled content in their fabrics, REPREVE uses a tracing technology that verifies recycled content claims.

Here is a list of my favourite sustainable swimwear brands that cover a variety of styles to suit every body type:
