Why consider a sustainable swimsuit?

One word: plastic. You see most conventional swimwear brands are made using different types of synthetic materials (plastics) like polyester, lycra, spandex, and nylon, all of which come from the petroleum industry and are not sustainable at all.

And if you have ever owned one of these, who hasn't? You know they have a tendency to stretch and fall apart very quickly. These types of suits are not biodegradable and can also shed tiny pieces of plastic called microfibers when you wash them!

And when you consider that an estimated 65 million tons of these plastic-based materials are generated every year, all around this is not a good look.

Conscious swimwear is a conundrum because most brands (even the eco ones) are using synthetic fabrics, buts that's okay when done properly!

Fabrics like recycled polyester (also known as Repreve® and EcoLux™) as well as recycled nylon which is made from recycled fishing nets and called Econyl are common in the sustainable swimwear category.

There are benefits to using recycled materials (mostly spandex/elastane) in this way, we are reusing what already exists which means fewer fossil fuels, and using recycled fishing nets keeps harmful plastic pollution from killing or harming marine life.

What is eco swimwear made from?

Anytime we invest in slow fashion, whether that be sandals, dresses, sneakers, or undies we want those items to last, and the same goes for sustainable swimwear brands.

As mentioned you will see most of the brands below offer suits made from Lycra spandex/elastane that come with certifications like Global Recycled Standard (GRS), OEKO-Tex 100Bluesign, and Forest Stewardship Council (FSC).

What to be on the lookout for when shopping for sustainable swimwear

As with all the ethical fashion articles on The Eco Hub, we take the following four criteria into account:

The fabric and materials: are they sustainable? In the case of swimwear are they coming from recycled products? Do they have third-party certifications like the ones noted above?

Ethical sourcing: where and how is the fabric sourced? Are the workers paid a fair wage and do they work in safe and fair conditions? Are the factories where they work certified byILOFair Labor AssociationWRAPFair TradeISO 14001SA8000BSCISMETAETI, or GOTS?

Corporate responsibility: is the brand taking the extra mile with its packaging? Are they carbon-neutral, a B Crop? Do they work with charities?

Inclusivity: It's all about size inclusivity, ALL bodies deserve to look and feel fabulous.

Final thoughts on sustainable swimwear

Like anything where slow fashion is concerned, we want to invest in things that last, and sometimes that means spending a little more money. If you have it! We are not all lucky enough to be spending money on a bathing suit, we get that! But where you can opt for the more ethical choice goes a long way in protecting people and the planet's natural resources.
