15 Ethical & Sustainable Swimwear Brands for Summer Bliss

Sustainable Swimwear

Are you looking to hit the beach in beautiful and sustainable swimwear that makes you feel and look wonderful? 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.

But before you pack your vegan sunscreen and wooden sunglasses, 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. As far as we know there is no way of getting around or removing plastic from swimsuit material with the textiles we have available today.

Similar to ethical underwear the most popular swimsuit fabrics are polyester and nylon – both of which are made from plastic as mentioned. And as you may know from our 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.

Where there is a will there is always a way!

Sustainable Swimwear Fabric Options

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

ECONYL® which is made from regenerated nylon. ECONYL® 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 landfills and the ocean.

These plastics are recycled back to their 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 for full transparency. At the time of writing, this post over 20 billion plastic bottles has been recycled to make REPREVE® fabrics.

These fabrics are a good option but aren’t always clearly listed on clothing labels, so you’ll have to dig a little deeper when evaluating options. The durability of these fabrics also plays an important role.

Filtering Microplastics when Washing Swimwear

Currently, there are two ways to filter out microplastics when you wash items of clothing, the first is using a Guppyfriend bag like this. With the Guppyfriend bag, all you do is put your swimsuit or other plastic containing fabrics within the bag before you put it in the washing machine. Then wash as normal – pretty easy!

And the second option is to invest in this Filtrol, microfibre filter. The Filtrol attaches to the outlet pipe of your washing machine and is perfect for filtering microplastics during every wash. We love this option as you only have to clean the filter out once in a while and forget about the process otherwise. It just does its thing in the background, which is a great timesaver.

Both of these options can be used to stop microplastic fibres from entering the outlet of your washing machine, which means you’ll be able to reduce the damage caused by washing plastic containing fabrics. When you wash any fabrics using an eco-friendly and zero waste laundry detergent will help to minimise environmental toxins from detergents.

Buy Classic Swimsuits that Last

To help reduce the environmental impact of your clothing and swimwear we recommend that you look out for items that will last. Avoid cheaply made fragile fabrics and poorly constructed seams – as the seams often fail before the fabric. Specifically, look for styles that are a bit more forgiving when you lose or gain weight.

And of course, taking good care of your suit will help it last longer, be careful when applying sunscreen as this can weaken and/or stain the fabric.

Disposing of a Swimsuit

Once your favourite swimsuit has come to end of life, make sure that you dispose of it responsibly so that it does not end up in a landfill – unless your suit was specifically created to decompose in a landfill for e.g. Frankies Bikinis listed below.

Our advice is to check with your local council or local authority to see if they have a clothing recycling programme as you’ll be able to recycle your swimsuit along with other clothing items.

Closing Thoughts

Living more sustainably is not a perfect journey. We often have to do the best we can and wait for technology to progress before we can make 100% sustainable choices.

Swimsuits are also not normally suitable for donation, but there are other options. For a few ideas read our post on what to do with old clothes that cannot be donated.

The fabrics used for swimsuits are still made of plastic and will shed microplastics when you’re swimming, but you can reduce the microplastics that enter the water system during the washing process by using a Filtrol or a Guppyfriend bag.

When you do buy swimwear that is made of recycled plastic you are in essence helping to make recycling more economically viable as you are helping to create demand for this type of plastic. This means that we have a chance to reduce the amount of “virgin plastic” used as well as the widespread pollution it causes when discarded.

Even though these fabrics aren’t perfect it’s a whole lot better for the planet overall than buying a swimsuit from non-recycled plastic fabric.
