More life in the water.
This is the story of why we built Earthcove — and what we did about it.
CHAPTER 1
The question that started it all - from our founder Emma Bianco
Most brands start with a product. Earthcove started with a question.
"Why is all swimwear made entirely from plastic fabrics?"
I'd been founder and CEO of plastic-free children's brand Pure Earth Collection for six years when this hit me. My whole business was about keeping children away from microplastics. Yet my own kids spent every summer in plastic swimwear, because I couldn't find a natural alternative.
So I set out to make one. GOTS certified organic fabrics instead of plastics.
Sampling was quick. My children had natural fabrics to swim in that summer. But I wasn't launching anything until we'd tested it through a full season of sun, sand and swims. Thinking there must be a reason everyone else used plastic! Maybe ours would disintegrate in salt water, or lose their shape after a few wears?
None of that happened. The cotton swimwear outperformed the synthetics, lasting at least twice as long before sagging or bobbling.
So in spring 2024, we launched, and it sold out in two weeks. Then came hundreds of requests for adult styles.
What began as one mother's quest to get plastic out of her children's summers became Earthcove. A new brand born from Pure Earth Collection now with a home of its own.
CHAPTER 2
What's actually in the water
Most swimwear is made from plastic. Polyester, nylon, ECONYL. Synthetic fabrics became the industry default because they're cheap, stretchy and fast-drying.
What doesn't get talked about is what they do. Every time a synthetic fabric is worn, washed or rinsed, it sheds tiny plastic fibres. Into the water around it, and into us. Those fibres don't break down. Research links them to hormone disruption in humans, and they're turning up inside our sea life and damaging our coral reefs.
Synthetic fabrics account for around 70% of global textiles. Most people never question what's in their swimwear. For children, it matters more. Their bodies are still developing. They spend long, happy hours in hot weather with this fabric against their skin, including their most absorbent areas. What it's made from matters.
All of them end up in the water.
CHAPTER 3
The fabric breakdown
What Earthcove is made from - and how it works
98% certified organic cotton. 2% lycra. That’s it.
Earthcove is built from a minimum of 98% organic cotton, certified by the Global Organic Textile Standard (GOTS). GOTS is the most rigorous independent certification for organic textiles, covering the whole supply chain from farm to finished garment. The 2% lycra gives stretch and shape retention. Free from PFAS and BPA.
The inverse of standard synthetic swimwear, which is 100% plastic.
UPF 50+ — no spray, no coating
UPF 50+ — Independently verified. No spray, no coating.
Earthcove fabrics are UPF 50+ without chemical finishes. The protection is in the weave itself, a denser knit that leaves less room for UV to pass through. Independently tested by [NAME].
Free from PFAS, phthalates, BPA and toxic dyes
PFAS, aka forever chemicals, are very often added to swim fabrics for quick-dry or water-resistant qualities. They bioaccumulate in our bodies and never break down in the environment. Research into their presence in humans and the associated health risks is building.
Phthalates are added to plastic yarn to make it soft and fibre-like. BPA, formaldehyde and toxic dyes are far too common too.
Earthcove is strongly against performance chemicals. We never use PFAS, BPA, phthalates, formaldehyde or azo dyes. Every dye and print is GOTS approved.
CHAPTER 4
Non-toxic by design
GOTS
GOTS is the gold standard for organic textiles. It covers the entire production chain, from farming, spinning, weaving and dyeing to the finished garment, checking for harmful substances and protecting worker rights at every stage. A GOTS certificate is only given to a supply chain independently audited throughout.
Earthcove products are GOTS certified across the range.
MANUFACTURING
Earthcove is manufactured through GOTS certified partner mills and Sedex approved factories.
PACKAGING
We eliminate unnecessary plastics at every stage. Our packaging bags are reusable organic cotton drawstring pouches. Mailing boxes and packing tape are biodegradable. Swing tags are card with natural jute string.
Awards
We’re proud to have won over six prestigious industry awards for our swimwear designs and high environmental standards.
Our awards include:

What We Stand For
These are the principles behind everything we make — from the materials we choose to how our products are made, tested and designed for life outside.
Natural first, always
No recycled plastic yarns and no greenwashing around recycled synthetic fabrics. We lead with organic cotton.
Less plastic in the water
Dramatically reduced microplastic shedding compared to synthetic swimwear.
Non-toxic by design
Free from synthetic chemicals at every stage of production. GOTS certified.
Made for real life outside
UPF 50+. Shape retention. Built for families on adventures.
Proven, not promised
Every claim is independently certified. GOTS certified. UPF tested. No greenwashing. No vague eco language. Just a supply chain we can stand behind.
Less plastic against your body. Less plastic in the water. It starts with what you choose to swim in. Follow the journey on Instagram @earthcoveswim, or join our newsletter for new arrivals, ocean education and stories from Emma.
