Our Best Sustainable Swimwear Brands For Kids & Babies Guide

Choosing the best eco-friendly kids’ swimwear can be tricky, especially if you’re searching for sustainable brands that use planet-friendly materials and ethical supply chains.

Finding sustainable swimsuits for kids and eco-baby swimwear for ultimate sun protection may seem daunting, but you’ll be happy to hear that there are more brands out there than you may have thought that are making swimwear with both children and Mother Earth in mind.

From cute one-pieces and bikinis to swim tops, swim shorts, and rash guards, this is the ultimate guide to the best swimwear for kids!

Our team has compiled a list of the best sustainable swimwear brands that kids and parents will love equally. Safe, protective, and fun –seriously, what more can we ask from the most noteworthy eco-friendly kids’ swimwear brands?

What is sustainable swimwear? 

Sustainable swimwear for kids is crafted with a focus on environmental and social responsibility throughout its production lifecycle. Think of recycled or upcycled fabrics such as cycled nylon, recycled polyester, and other regenerated materials to help reduce the demand for new resources and minimize waste.

On top of that, sustainable swimwear brands prioritize fair labor practices, ensuring that workers involved in the manufacturing process are treated ethically, paid fair wages, and operated in safe working conditions.

What material makes the best sustainable kid’s bathing suits?

Organic Cotton

Organic cotton is a natural choice for sustainable kids’ swimwear. Grown without synthetic pesticides or fertilizers, organic cotton promotes healthier soil and ecosystems.

While less common in swimwear due to its water-absorbing nature, organic cotton is sometimes blended with other materials to provide a comfortable and breathable option for children who may have sensitivities to synthetic fabrics.


TENCEL, derived from sustainably sourced wood pulp, is a suitable material for eco-friendly kids’ swimwear. Known for its softness and breathability, TENCEL provides comfort while also being biodegradable.

While not as commonly used in swimwear as synthetic materials, TENCEL offers a natural alternative for parents seeking sustainable options for their children.

Recycled Nylon 

Recycled nylon is a popular choice for sustainable kids’ bathing suits. It is created by repurposing post-consumer waste, such as discarded fishing nets and fabric scraps.

This process helps reduce the demand for new resources and minimizes environmental impact.

Recycled nylon maintains the durability and flexibility needed for swimwear, making it an excellent choice for active kids who love to splash and play in the water.

Recycled Polyester

Another sustainable material for kids’ swimwear is recycled polyester. This fabric is made from recycled plastic bottles, diverting plastic waste from landfills and oceans.

Recycled polyester retains the quick-drying and moisture-wicking properties necessary for swimwear, ensuring that kids stay comfortable both in and out of the water. 

This post is all about the best sustainable swimwear brands for kids & babies.

Sustainable Swimwear FAQs:

What sustainable swimwear is best for kids?

Sun safety is a big factor in deciding which sustainable swimwear brands are worth the investment. Rash guards or sun shirts are a great option for sun protection for kids of any age, as they provide a physical barrier from the sun and have UV protection within the fabric.

This makes life a lot easier as you won’t need to reapply as much sunscreen underneath the swimsuit in between swims! Good Weekend, Noma, Reima, and Elle Evans have created amazing sun-safe rash guards and sun shirts for babies, toddlers, and kids!

Remember, the best sustainable swimwear brands for kids should tick all your quality and safety boxes, given that children under age 10 are at high risk for skin and eye damage from UVR.

What is the most durable material used for swimwear? 

One of the most durable materials commonly used for swimwear is recycled polyester. Polyester fabric is known for its excellent strength, resistance to stretching, and ability to retain its shape over time. 

Polyester is highly resistant to the deteriorating effects of chlorine found in swimming pools. This resistance helps the fabric maintain its color and structural integrity even with regular exposure to chlorinated water.

What’s more, the fibers have low water absorbency, which means they don’t stretch out of shape when wet. This property helps swimwear maintain its original fit and structure, providing long-lasting wear.

On top of that, polyester dries relatively quickly compared to some other fabrics, reducing the time your swimwear spends damp and minimizing the risk of mold or mildew.

And lastly, polyester tends to retain color well, resisting fading from exposure to sunlight, saltwater, and chlorine. 

How do I choose eco-friendly swimwear for my baby?

Choosing sustainable children’s swimwear will depend on their age, size, and what type of water they’ll be swimming in.

For example, if you’re buying an eco-friendly swimsuit for your child to take swimming lessons, you’ll want one that is chlorine-resistant, but if you’re off on your holiday to the sea, you might want a swimsuit that provides more warmth as the temperatures can be less predictable.

Color selection is also important, as different colors can be safer for children to wear while swimming, especially in lakes and oceans.

Overall, the questions to ask yourself when picking out a swimsuit for your child are: 

  1. Is it durable? (so it can last as long as possible!)
  2. Is it sun-safe? Does the material have UV protection?
  3. Is it the right color? Will the swimsuit be visible enough while my child is swimming?
  4. Is it designed for where we’ll be swimming? Think chlorine or salt water, warm or cold water, and activities. You might want fuller coverage for more protection if they are bodyboarding, surfing or rock pool exploring.

What color swimsuit is best for children?

Another aspect you may not have considered is the color of the swimsuit and how safe it is for children. Swimsuits in bright, neon colors such as orange, yellow, and green can help parents and lifeguards easily spot children in a body of water or a crowded beach.

Colors such as blue, black, and natural green can make it incredibly tough to spot your child from a distance when they’re in the sea or a pool. 

Other design elements such as characters, animals, or patterns can also help you describe the sustainable swimwear your child is wearing if they do happen to wander off.

Let’s not forget that experts suggest that colors such as blue, red, and all types of vivid hues are the best for sun protection compared to white or pastel colors of the same fabric.

These are key things to remember when picking your little ones’ swimsuits for the year.

How do I care for swimwear, so that it lasts longer? 

Rinse After Use 

Rinse your swimwear with cool, clear water after each use. This helps remove salt, chlorine, and sunscreen, which can contribute to fabric deterioration.

Hand Wash

Hand wash your swimwear with a gentle detergent. Avoid using harsh chemicals, as they can damage the fabric and affect color.

Avoid Hot Water

Use lukewarm or cool water for washing. Hot water can weaken the elasticity of the fabric over time.

Gently Pat Dry

Gently pat your swimwear dry with a clean, soft towel. Avoid wringing or twisting the fabric, as it can damage the fibers.

Avoid Wrapping in Towel

Don’t wrap your wet swimwear in a towel for an extended period. This can create a damp environment, leading to mold or stretching.

Skip the Washing Machine

Avoid using a washing machine, as the agitation and spinning can damage the fabric and cause stretching.

Dry Flat

Dry your swimwear flat on a clean, dry towel. Avoid hanging it, as the weight of water can distort the shape.

Avoid Direct Sunlight

Dry your swimwear in the shade to prevent fading caused by direct sunlight.

Be Cautious with Sunscreen

Apply sunscreen before putting on your swimwear to avoid direct contact with the fabric. Some sunscreen ingredients can cause discoloration.

How do I wash swimwear? 

After wearing your swimwear, rinse it immediately with cool, clear water to remove salt, chlorine, and sunscreen, which can be damaging over time.

Fill a basin or sink with lukewarm water. Add a small amount of mild detergent specifically designed for delicates or swimwear. Gently agitate the water to create suds. 

Avoid excessive rubbing or wringing, as this can damage the delicate fabric. If there are specific stains, gently rub them with your fingers. Avoid using a brush or abrasive materials that can damage the fabric. Drain the soapy water and rinse the swimwear under cool, running water until all detergent is removed.

Gently pat the swimwear with a clean, soft towel to absorb excess water. Avoid wringing or twisting the fabric, as it can cause stretching. Then, lay the swimwear flat on a dry towel to air dry. Reshape the swimsuit to its original form to avoid distortion.

P.S. Never use a dryer to speed up the drying process. High heat can damage the elasticity and fibers of the fabric.

    I know Boden are eco friendly with their materials, but would they also be considered non toxic?

    • Hi Mary, this is a tough question. When it comes to swimwear, there are no brands that we found that did not use some type of polyester or recycled polyester (repreve or regenerative). The only thing we can do to ensure the fabric is considered “non toxic” is to look out for the OEKO-TEX certification. This cert isn’t perfect, but it does ensure that the fabric is at a much higher safety standard than others: This label certifies that every component of the product, from the fabric to the thread and accessories, has been rigorously tested against a list of up to 350 toxic chemicals. The brands that have this standard are Good Weekend, Frugi, Hannah Anderson, and Ina Swim.
