Craving the salty seas of foreign isles? Down to your sustainable skivvies, summer is almost here! Regardless of our ability to cross country borders, warmer months will soon be upon as which demands swimwear with aesthetics and ethics.

Last year, Missguided broke the internet with their infamous ‘£1’ bikini, a succinct summary of everything that is wrong with fast fashion retailers not bearing the true cost that garment production has on the people or planet.

The infamous £1 bikini by Missguided

For the majority, swimwear is seasonal, worn only on a handful of vacations, in heavy rotation with numerous other pieces to make a splash and parade poolside. Costume fabrics are often cheaply made, see through bikini bottoms or snapped elastic straps is something I’m sure many readers will have experienced. As a post mortum, these are then discarded, further fuelling our unhealthy relationship with landfills for barely used clothing. The plastic footprint of swimwear, despite its skimpy use of material, still accrues quite the environmental impact, whether its energy intensive processes of manmade textiles or the shedding of microfibres in washing. Preservation is equally as important as the quality of what you purchase. Appropriate care can prolong a garments life span as sand, sunscreen, chlorine or our favourite tanning lotions are all abrasive on our swimsuits.

Whilst it seems like a mere drop in the ocean, there are an entourage of innovative brands taking the plunge to clean up plastic pollution and save the seas one swimsuit at a time. These durable high-performance pieces keep perfect after rigorous water sports or leisurely lolling on the sand. As smaller labels, they focus on made to order supply chain strategies, purposefully keeping collections conservative to mitigate unsold stock waste. What’s more, their charitable endeavours see many donate profits to organisations dedicated to cleaning up the oceans. (To read more about the ocean’s plastic problem read here).

So how do they do it? Fabric innovation is critical. If you’ve read my other spotlight features, you will be familiar with ECONYL® and other materials such as Tencel and OEKO-TEX® that embrace circularly to reduce waste. Material consideration is fundamental, especially for the lining, which makes up of 50% of swimwear fabric consumption and is often overlooked.

As a brief recap, ECONYL® has pioneered a closed loop regeneration processes to transform the abundance of nylon waste that resides in landfills and oceans worldwide into sustainable textiles. This motivation of biomimicry has seen the reimagining and development of a material that is 100% regenerated and 100% regenerable infinitely.

Their four-stage process of rescue, regenerate, re make and reimagine has seen that for every 10,000 tons of ECONYL® raw material, they are able to:

  • Save 70,000 barrels of crude oil
  • Avoid 57,100 tonnes of CO2 emissions.

It reduces the impact on climate and contribution to warming by up to 80% compared with materials from oil.  Their collaboration with the Healthy Seas Initiative looks to eradicate and unsully the oceans of marine litter to combat ghost nets and ghost fishing.

From top trunks, bottles turned into bikinis and pool side performers that fight against ghost fishing, these high-quality swimwear brands will help you make a sustainable splash.

P.S. For my male readers, trunks via Outerknown and Finisterre will keep you swimming sustainably.

Founded by Natalie Glaze and Zanna Van Dijk, Stay Wild Swim is a London based business that has won the 2020 Positive Luxury award for Breakthrough Brand. Their pieces are feminine and functional and my personal favourite is the Nerida bikini.

Davy J – one for the water sports fanatics as they are ‘designed to survive the dive’. Another opportunity to champion a British business, Davy J ECONYL® swimsuits are as sturdy and durable as they are stylish. Their pieces have double lining with high elastane composition for extra strength and shape staying power. They also have rubber edging to ensure no slippages!

Their mantra of wear more, wash less endorses correct garment care.

Vitamin A  – having partnered with the likes of Patagonia, founder Amahlia was determined to transform the swimwear game. Vitamin A is a Southern Californian pioneer that uses ECOLUX, OEKO-TEX® and recycled nylon fibres to form its fitting pieces. They represent best practice as they not only do they use waterless processes to print their designs that reduce chemical and water usages, they partner with artisan groups in the region to strengthen community collaboration. One of my favourite things about Vitamin A is they measure the tangible positive impact they have made thus far. As of May 2020, they have: saved over 1.7 million litres of water, diverted 32,000 kg of waste, avoided nearly 300,000kg of emissions and saved over 938,000 khw energy through their processes.

They also use a BioSculpt material which is plant based and raw sourced from castor bean, a great alternative to nylons! Their enviable ethical loungewear is not to go amiss either.

The UK based brand is vegan, fully certified by the OEKO-TEX® standard and their workplace is even fuelled by renewable energy!

Batoko’s swimsuit initiatives are award worthy, for example for every Lobster swimsuit sold, they rear a baby lobster and release it back into the sea – a win-win! Their partnerships see them donate a portion of profits to the Marine Conservation Society UK and collaborate with Mossy Earth for any carbon they can’t reduce by offsetting it by restoring native forests throughout Europe.
