7 Sustainable Swimwear Brands to Float Your Boat This Summer

7 Sustainable Swimwear Brands to Float Your Boat This Summer

Shopping for sustainable swimwear, whether it’s a one-piece, two-piece, board shorts or trunks, can be a bit overwhelming.

I don’t know about you, but the purchase has lots of excitement and anticipation. Perhaps it’s for a summer holiday, or looking forward to re-visiting the lido, or for an upcoming triathlon. But for the conscious shopper, the quest for ethically made swimwear can also be incredibly frustrating.

The uncomfortable truth is that pretty much all swimwear is made from plastic-based fabrics. Polyurethane (Lycra, Spandex or Elastane), Polyester, Nylon or blended synthetic fibers such as Poly PBT or XLA are your usual suspects. These materials are great for swimwear, because they wick moisture and stretch across the body to reduce friction in the water. But boy are they bad news for the environment. Being plastic, they do not biodegrade and instead sit in landfills or oceans forever. This adds to the estimated 8 billion tons of plastic that already exists on this Earth!

A lot more work needs to be done to find an alternative, sustainable fabric for swim and activewear that carries the same performance qualities as the ones mentioned above.

In the meantime, we can look to eco- and ethically-conscious brands who use recycled materials and a sustainable processes. They are producing stunning, ethical swimwear that you’ll be proud to walk out onto the beach / lido / triathlon start line!

Sustainable Swimwear For Good Times

There is still so much to do when it comes to cleaning up the oceans. Sustainable swimwear is a strong step in the right direction and it keeps going strength to strength. Through taking waste and turning it into our favorite swimwear pieces, we are literally moving trash into treasures. There is still a long road ahead but it is amazing to see strong brands tackle the challenge head on.

At Compare Ethics, we are committed to bringing sustainable swim into the mainstream. It should be standard that businesses innovate and provide new ways to tackle ocean waste. It was consumerism that got us into this mess. Its about time we got ourselves out it.  The power is in our hands, we just have to protest with our purchases.
