Does Plastic-Free, Organic Swimwear Even Exist in 2023?!

---

There is no shortage of beautiful, eco-friendly, and high-quality swimwear made from recycled materials. There are lots of brands using ECONYL, for example, which is made using regenerated nylon fibers that come from old fish nets and other materials that would otherwise just fill up landfills. (And we’ve included some of those brands in this article.)

But what if you want a plastic-free swimsuit that’s actually free from synthetic materials and made with natural and/or organic fabrics instead?

Well, those are a lot harder to find, and in some cases, nearly impossible. But we’ve searched high and low and in this guide, we are bringing you the best organic cotton, hemp, and plant-based swimwear for the whole family. And in the cases where plastic-free, organic bathing suits aren’t available, we’re giving you the best alternative options to choose from.

P.S. Here are some related guides you might be interested in to refresh your warm weather wardrobe:

Kaylyn Gardner (100% Organic Cotton)

Materials: Organic cotton
Carries: Women’s (one- and two-pieces), Girls (two-pieces), Loungewear (cardigans, arm wraps, etc.)
Made in: USA
Price range: $100-$300

This is one the very few brands (maybe even the only brand) you’ll find that’s made out of 100% organic cotton. Each one of these knit swimwear pieces is handmade and dyed using avocados!

They offer several different styles of one and two pieces, and they even have a super cute matching Mommy & Me collection that comes with a girls’ swimsuit. Keep in mind that since they are completely free from any synthetic stretchy fabric, they aren’t going to fit the same way other conventional swimsuits will. They may not be the best fit for active water sports or intense swimming, but they’re great for lounging around the pool or beach and dipping in the water!

They also offer other kinds of knitwear like pullovers and shorts that you can lounge around in after a day at the pool or beach.

Vitamin A (Best for Active Water Sports)

Materials: BioSculpt
Carries: One pieces, two pieces, activewear, rash guards,
Made in: California, USA
Price range: $170-$295

Although a lot of their bathing suits are made from recycled materials, they also have a “plant-based” collection, which is plastic-free.

This collection is made out of BioSculpt fabric, which is a polymer that’s made from castor beans. It has a lot of the properties of synthetic fabric—it’s durable, it dries pretty quickly, and it’s super smooth.

As a brand, Vitamin A is committed to ethical and sustainable practices throughout their supply chain, too. They do regular beach cleanups, they give back 1% of profits to environmental non-profits, and they use recycled and biodegradable packaging.

Oh, and this collection is gorgeous, too. I actually purchased one of their BioSculpt suits last year and I really like it. It’s not as stretchy as you might be used to with swimwear, but the fabric is thicker and feels more durable. So not only does it feel like it will last longer than an alternative, but I also feel thoroughly “held in” to the suit when I’m swimming or running around in it. These aren’t the most affordable suits, but it does seem like they will last longer than other brands and materials.

Patagonia (Best for Neoprene-Free Wetsuits)

Materials: Yulex
Carries: Wetsuits for men & women
Price range: $199-$549

Patagonia has a collection of wetsuits that are made from a branded fabric called Yulex. Yulex is made from FSC certified natural rubber instead of traditional neoprene, which is sourced from oil and/or limestone.

These wetsuits are not only more sustainable, but they’re just as high-performing for water sports and they’re Fair Trade certified, too.

Shop Patagonia

Finisterre and SLO Active are two other brands using Yulex for their swimwear and wetsuits.

I’d still like some more transparency about the chemicals involved in the manufacturing process of both BioSculpt and Yulex (is it a rayon type of situation?), but I’m sure they’re both still better options than their petroleum-based plastic alternatives, both for you and for the planet.

Hemp Huggers (Most Customizable)

Materials: Organic hemp, organic cotton, and latex-free lycra.
Carries: Bikinis, one-pieces, beach clothing
Made in: USA
Price range: $48-$182

Their website may look like it’s from 2002, but don’t let it fool you: this brand actually has some great options for organic swimwear that’s made from hemp and cotton. The lycra they use is latex-free, which means it’s hypoallergenic and a great option for even the most chemically-sensitive person.

They have a lot of different options (mostly for women) and the suits are suuuper customizable—you can choose the type of fabric, type of dye, cup size, and more.

Pros & Cons of Natural vs. Synthetic Fabrics for Swimwear

As you can see, 100% natural, plastic-free, and organic swimwear is hard to come by. Even the majority of those that are made from mostly natural materials still have a small percentage of synthetic material like spandex or nylon.

This is usually for performance, fit, and durability reasons. Most people want a bathing suit that fits tightly (even when wet) and that sticks close to their skin so they don’t have to worry about any *wardrobe malfunctions.*

Of course, what you really need in a bathing suit is going to vary depending on whether you’re just laying around the pool, surfing, walking around a resort all day, running to catch up with the kids on the beach, or whatever.

Depending on your needs, swimwear may be one of those categories where you might just have to go with an option that contains at least some plastic for now. That’s okay—just choose the best option you can based on all of the varying factors involved.

Of course, swimwear made from synthetic fabrics has its shortcomings, too (even if it’s recycled). The most obvious problem is that synthetic swimwear (and other types of fabrics) shed microplastics as you wear and wash them. Microplastics are not healthy for our ecosystems, nor the animals and humans involved.

Catch Those Microplastics!

If you do decide to go with a suit that’s made from recycled synthetic materials, there are some things you can do to minimize the amount of microplastics that enter our waterways when you put your suit through the wash. (These are also good for any other types of synthetic clothing as well!)

• You can place your suit into a Guppyfriend bag before putting it in the laundry.
• For larger loads, you can just throw a Cora Ball in your washing machine and it will catch a certain amount of microplastics for you.
• Or you can grab one of these washing machine attachments.

So, there you have it. 100% plastic-free, natural, and organic swimwear is quite difficult to come by, but hopefully this guide has given you some BETTER options to choose from.

And don’t forget: stress can be toxic, too. So instead of worrying TOO much about how much about trying to make the perfect decision when it comes to sustainable and organic swimwear, just make the best decision you can with the options you have.

And then… HIT THE BEACH AND HAVE FUN!
