Our Best Sustainable Swimwear Brands For Kids & Babies Guide

Sustainable Eco Friendly Kids Swimwear

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 rashguards, 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 material makes the best sustainable kid’s bathing suits? 

The most sustainable material for kids’ swimsuits (of all ages) is ECONYL, a regenerated nylon made from landfill and ocean waste such as ‘ghost nets’ (abandoned plastic fishing nets). Brands like Good Weekend and Ina Swim use Econyl in their sustainable children’s swimwear to save plastic waste from the ocean and landfill without sacrificing the quality of their products.

When choosing eco baby swimwear, the most important factors are skin sensitivity, warmth, room to move, and UV protection. Brands like Hanna Andersson and Ina Swim have some of the best sun-safe and skin-safe sustainable baby swimwear on the market.

What sustainable swimwear is best for kids?

Sun safety is a big factor in deciding which sustainable swimwear brands are worth the investment. Rashguards 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 rashguards 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.

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: 

  • Is it durable? (so it can last as long as possible!)
  • Is it sun-safe? Does the material have UV protection?
  • Is it the right color? Will the swimsuit be visible enough while my child is swimming?
  • 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 rockpool 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.

    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.
