You might think that biodegradable swimwear falls apart when you swim. This is not true. Biodegradable means the material breaks down naturally over time, but only when exposed to the right conditions. Many brands call their products eco-friendly, but they often use recycled plastics. These plastics can still shed microplastics and harm the environment. Truly biodegradable swimwear uses natural fibres like merino wool or hemp, which break down safely and do not add to pollution.
Key Takeaways
Biodegradable swimwear does not fall apart when worn. It breaks down naturally only under specific conditions, like in soil or landfill.
Not all eco-friendly swimwear is biodegradable. Many brands use recycled plastics that do not decompose naturally.
Always check the material label before buying swimwear. Look for plant-based fibres or certified biodegradable yarns.
Choose brands with trusted certifications to ensure their sustainability claims are backed by science.
Biodegradable swimwear helps reduce pollution and waste, supporting a cleaner planet when you make informed choices.
Is Biodegradable Swimwear Sustainable?
What Makes Swimwear Biodegradable
You might wonder what makes swimwear truly biodegradable. The answer lies in the materials used. Biodegradable swimwear uses fibres and yarns that break down naturally when exposed to the right conditions, such as soil, moisture, and microorganisms. This process does not happen while you wear the swimsuit or when it gets wet in the pool or sea.
Some materials recognised by scientific organisations for their biodegradable properties include:
Biodegradable nylon yarn OEKO Tex, used by brands like Second Summer.
Amni Soul Eco® and ROICA® bio stretch, a custom blend found in Monte & Lou swimwear.
Econyl, often mentioned for sustainability, but not classified as biodegradable.
You can see that not all materials labelled as "eco-friendly" are biodegradable. Many brands use recycled plastics, which help reduce waste but do not break down naturally. Biodegradable swimwear stands out because it uses fibres that return to nature without leaving harmful residues.
Tip: Always check the material label before buying swimwear. Look for plant-based fibres or certified biodegradable yarns.
Sustainability Claims vs Facts
Many brands make bold claims about sustainability. You may see words like "eco-friendly," "recycled," or "biodegradable" on tags and websites. It is important to know what these claims mean and which ones are backed by science.
Here are some common sustainability claims made by swimwear brands:
Davy J uses recycled fabrics and works with UpCycle Labs to recycle old swimwear.
Public Myth highlights natural, biodegradable fibres such as Merino Wool and Bamboo/Cotton blends. These materials decompose naturally and do not pollute the ocean.
Some brands use Econyl, made from recycled ocean waste, which reduces the environmental impact of nylon production by up to 90%.
Davy J's Zero Trace swimsuit uses fully biodegradable nylon yarn, showing a commitment to sustainable materials.
You should know that traditional swimwear made from nylon and polyester does not break down. These fabrics contribute to landfill waste and ocean pollution. The production of polyester and nylon also releases greenhouse gases, which harm the environment.
Fast fashion creates 92 million tons of textile waste every year. Brands like OHOY Swim use regenerated nylon from ocean plastic to promote sustainability. PANGAIA introduced PEBAX RNEW®, a plant-based elastomer, as an alternative to synthetic fibres. Adidas launched a zero-waste swimwear collection that is fully recyclable. FlexSea is developing seaweed-based textiles that decompose naturally.
California-based Vitamin A offers the ReLux collection, made from 100% recycled fabric, including 80% recycled nylon from fishing nets. This shows how brands can use innovative materials to reduce their impact.
Note: Sustainability claims should be backed by material science. You can trust brands that provide clear information about their materials and certifications.
Biodegradable swimwear offers a real solution to textile waste and pollution. When you choose swimwear made from natural or certified biodegradable fibres, you help protect the planet and support responsible fashion.
Biodegradable Swimwear Myths
Myth: It Disintegrates When Worn
You might worry that biodegradable swimwear will fall apart while you swim. This is a common misunderstanding. Scientists at Scripps Oceanography tested different fabrics in the ocean. They found that natural cellulose-based textiles broke down in about a month. However, bio-based and oil-based materials, which are often used in biodegradable swimwear, stayed strong for over a year. This means your swimsuit will not break down during normal use in the pool or sea. You can swim, sunbathe, and wash your suit without fear of it falling apart.
Remember: Biodegradable does not mean weak or short-lived. It means the material will break down only under special conditions, like in soil or landfill, not while you wear it.
Myth: All Eco-Friendly Swimwear Is Biodegradable
Many brands call their swimwear eco-friendly. You may think this means the swimsuit is biodegradable, but that is not always true. Eco-friendly swimwear often uses recycled plastics, like Econyl or recycled polyamide. These materials help reduce waste, but they do not break down naturally. Biodegradable swimwear uses special fibres that can decompose in a landfill within a few years.
Here is a simple table to help you see the difference:
Swimwear Type | Material Composition | Degradability |
|---|---|---|
Eco-friendly Swimwear | Econyl (regenerative nylon), recycled Polyamide | Not necessarily biodegradable |
Biodegradable Swimwear | Pyratex Active 1 (Oeko-Tex certified polyamide with enhanced biodegradation) | Decomposes within five years in landfill |
Myth: Biodegradable Means Quick Breakdown
You might believe that biodegradable swimwear disappears quickly. This is not true. The breakdown process needs the right mix of moisture, heat, and microbes. In normal use, your swimsuit will last as long as regular swimwear. Only when you throw it away and it reaches the right environment will it start to decompose. This helps reduce waste without sacrificing quality or performance.
Tip: Always check the label and ask questions if you are unsure about the materials in your swimwear.

Plant-Based Fibres
You may notice that many brands use plant-based fibres in their biodegradable swimwear. These fibres come from natural sources like cotton, hemp, bamboo, and linen. They break down in the environment with the help of moisture, heat, and microbes. You can feel good knowing that these materials return to nature without leaving harmful residues.
However, you should also understand the environmental impact of sourcing and processing these fibres. The production of cotton, for example, uses a large amount of water. It takes about 2,700 litres of water to make just one cotton T-shirt. Cotton farming also uses around 6% of the world's pesticides and 16% of all insecticides. The dyeing process for plant-based fibres often involves chemicals from coal and oil. These chemicals can pollute water and harm aquatic life if not handled properly. The process can also deplete natural resources and damage ecosystems.
The dyeing process uses chemicals that can pollute rivers and lakes.
Cotton farming relies on heavy pesticide and insecticide use.
Water use for cotton is very high, which can strain local supplies.
You should always look for brands that use organic or certified fibres and eco-friendly dyes. This helps reduce the negative impact on the environment.
Biopolymers in Swimwear
Biopolymers are another exciting material in biodegradable swimwear. These are special plastics made from renewable sources like corn, sugarcane, or even seaweed. You will find that biopolymers can mimic the stretch and durability of traditional swimwear fabrics. Some common biopolymers used in swimwear include PLA (polylactic acid) and PHA (polyhydroxyalkanoates).
You might see brands using yarns like Amni Soul Eco or ROICA bio stretch. These yarns break down much faster than regular nylon when placed in the right conditions. Biopolymers offer a way to enjoy the comfort and fit you expect from swimwear, while still supporting the environment.
Note: Biopolymers need specific conditions to break down, such as industrial composting or landfill environments. They will not degrade while you swim or wash your suit.
Benefits and Limitations
You gain several benefits when you choose biodegradable swimwear. These materials help reduce waste and pollution. They break down naturally, so they do not add to landfill problems. You support a cleaner planet by choosing these options.
However, you should also know the limitations. Plant-based fibres and biopolymers can still have an environmental impact during production. The dyeing process for plant-based fibres uses chemicals that can harm water sources and wildlife. Cotton farming uses a lot of water and pesticides. Biopolymers, while renewable, often need special facilities to break down fully.
Here is a quick comparison table to help you understand:
Material Type | Main Benefit | Main Limitation |
|---|---|---|
Plant-Based Fibres | Natural, biodegradable, renewable | High water use, pesticide use, pollution from dyes |
Biopolymers | Renewable, mimics synthetic fibres | Needs special composting, production impact |
You can make a difference by choosing brands that use certified materials and safe dyeing methods. Always check for certifications and ask questions about how your swimwear is made.
Comparing Biodegradable and Conventional Swimwear

Environmental Impact
You make a big difference when you choose what to wear in the water. Conventional swimwear uses synthetic fibres like nylon and polyester. These materials come from oil and do not break down in nature. They can stay in landfills for hundreds of years. When you wash these suits, they often release microplastics into rivers and oceans. Fish and birds can eat these tiny plastics, which harms wildlife.
Biodegradable swimwear uses natural fibres or special biopolymers. These materials break down much faster when you throw them away. They do not leave harmful residues behind. You help reduce pollution and waste by picking these options.
Swimwear Type | Breakdown Time in Landfill | Microplastic Pollution | Source Material |
|---|---|---|---|
Conventional | 100+ years | High | Oil-based |
Biodegradable | 1-5 years | Low | Plant or bio-based |
Durability and Performance
You might wonder if biodegradable swimwear lasts as long as regular suits. Many new materials offer strong stretch and hold their shape well. You can swim, dive, and play without worrying about your suit falling apart. These suits keep their colour and fit after many uses. You get comfort and support, just like with traditional swimwear.
Tip: Always follow the care instructions on your swimsuit. This helps it last longer, no matter what material you choose.
Safety for Skin
Your skin can react to different fabrics. Some people feel itchy or get red marks from synthetic suits. Organic and plant-based fibres feel soft and gentle. Many people with sensitive skin find these suits more comfortable.
A parent shared that her daughter, who has eczema, could not wear regular swimwear without itching or red marks. After switching to organic cotton swimwear, her skin stayed calm and comfortable.
You can enjoy swimming without worrying about irritation. Choosing natural materials helps protect your skin and the environment.
Choosing Biodegradable Swimwear
Reading Labels
You need to check the label before you buy any swimsuit. Labels tell you what materials make up the swimwear. Look for words like "plant-based fibres", "biopolymers", or "certified biodegradable". Some brands list the exact fibre, such as organic cotton or bamboo. You should avoid labels that only say "eco-friendly" or "recycled" without more detail. These terms do not always mean the swimsuit will break down naturally. If you see a label with technical names like Amni Soul Eco or ROICA bio stretch, you know the brand uses advanced biodegradable fibres.
Tip: If you cannot find clear information on the label, ask the shop assistant or check the brand’s website for details.
Certifications to Look For
Certifications help you trust the claims brands make about their products. You should look for third-party certifications that prove the swimwear meets strict standards. Some of the most trusted certifications include:
