Check out our top sustainable swimwear picks that are perfect for an eco-friendly summer


We’re taking a deep dive into the sustainable swimwear brands that are making a splash of green this summer.

Your typical fast fashion swimsuit is made out of synthetic materials such as Polyurethane which doesn’t biodegrade and is made from oil. Say hello microplastics, goodbye natural resources. But never fear! 

Plenty of sustainable swimwear brands are going against the tide and developing eco-friendly swimwear options, so, whether you’re having a lounge by the pool or a speedy swim, you can safely relax knowing that you’ve got Mother Nature by your side.

Tide + Seek are not only winning at the pun game, but they are also winning at saving the ocean. 

This sustainable swimwear brand doesn’t only kit you out for a good swim, but they are committed to making the waters less polluted when you do. 

All plastic bottles labelled with #1 on the bottom have the same chemical make-up as polyester (polyethylene terephthalate) – meaning the plastic bottle flakes can be reused by being transformed into swimwear, rather than being sent to landfill or, worse, blown into the sea and polluting our oceans.

REPREVE® is a polyester fibre made of 100% recycled plastic. What’s more, the production of the fabric offsets the use of new petroleum, emitting fewer greenhouse gases and conserving both water and energy throughout the process.

Topaz Swim have been creating sustainable swimwear since 2018 with hopes to keep learning and keep growing. The team believes in creating quality swimwear that lasts, with quality and luxury forming a bond that can’t be broken by time!

The swimwear brand is very upfront about their choice to use Lycra as a material in their swimwear, but they support many sustainable causes and practices that help them reduce their environmental footprint as much as possible. 

They firmly believe in slow fashion, making sure their materials are ethically sourced and of high quality. They use 100% biodegradable packaging, work with The MSC and One Tribe to protect both land and sea, AND work with their supply chain to transform fabric cut-offs into hair accessories. 

Now that’s the kind of teamwork that makes the dream work.
