5 Sustainable Swimwear Brands To pack With You This Summer

Summer is not near… it’s here! 
So we have compiled a list of swimwear brands that are Twin Flame approved. 
They are all ethically manufactured, eco-friendly, and founded by women just like us. 
But before we unveil the list let’s get back to basics. 

Why are conventional swimsuit brands a problem for our planet? 
Simple! Because most if not all swimsuit brands use nylon or polyester fabrics. These fabrics are made of fibers that are petroleum-based and do not biodegrade like natural fibers. Moreover, they shed microplastics when swimming or when being washed.
What is the solution?

When shopping for swimsuits look for pieces that are made of natural fibers or recycled fibers. 
Regarding recycled fibers we recommend you look out for ECONYL®. This fabric is 100% recycled and recyclable fiber. It is made from pre-consumer waste such as fabric scraps and post-consumer waste such as fish nets abandoned in our oceans. 
At Twin Flame we donate 1% of each purchase to the organization Healthy Seas to do just that: they collect abandoned fish nets in the sea and then transform them into ECONYL®.

Now let’s get down to business:



This brand has stolen our heart not only because of the jaw-dropping styles but most importantly because of their 360 sustainable approach. Away that day was created in 2018 by Ingemae with the purpose to finally offer eco-friendly pieces with flattering cuts and impeccable quality. 
All pieces are made of ECONYL: 100% recycled fiber made of pre and post-consumer waste and they are ethically manufactured in the heart of London. Each piece is slipped in 100% compostable packaging. 
The cherry on top of the cake? They offer a recycling program: send them any of your worn-down swimsuits and they will recycle them into industrial materials and you get a 15% discount on your new swimsuit! As they say out with the old and in with the new, the sustainable way.

Our favorite pieces by Away that day: The RIO top and bottom.

Even though recycled nylon is a good option, unfortunately, it still sheds microplastic in our oceans. So the solution to this is natural fibers this is why Natasha Tonic created her eponymous brand. All of her swimsuits are made of hemp which is antimicrobial, UV resistant, and durable. Growing hemp actually enriches the soil and uses less water than cotton to produce. All pieces are sewn and dyed in Los Angeles, USA.

Our favorite piece by Natasha Tonic: The HOT SHOULDER.

Medina is a luxury women’s swimwear brand with a purpose. All pieces are made of ECONYL and ethically manufactured in Europe. Lou Medina the founder had first a career in high fashion working for brands such as Céline and Alexander Mcqueen. This luxurious savoir-faire is clearly applied to her swimwear collections. The pieces are also versatile as the bold shapes and fine details allow them to transition perfectly into daywear pieces.

Our favorite pieces by Medina: The TROPIC top & bottom.

Does this brand need any introduction? Tropic of C is founded by Victoria's Secret supermodel Candice Swanoepole. Tropic of C does not offer 100% eco-friendly styles so make sure to shop in the “sustainable styles” part. In this section, you will find beautifully crafted, high quality and colorful pieces made out of ECONYL or REPREVE (This fiber is made out of 100% plastic bottles).

Our favorite pieces by Tropic of C: SOUTH PACIFIC top & CURVE bottom

Vitamin A is all about feeling good, looking good, and doing good. They offer endless styles and colors, all made of recycled nylon or plant-based fabrics. They donate 1% of each purchase to the organization “For the Planet” and also partner up with other organizations such as Greenpeace, Women’s Earth Alliance, or One Tree Planted.

Our favorite pieces by Vitamin A: Lolita Bottom and Misty Top

 And of course, the best way to protect our planet is to care for our pieces and make them last in time. This is how we recommend you do so: 

Always hand wash your swimsuits and air dry them away from the sun so the colors don’t fade away. 
Also if washing a swimsuit made of ECONYL or REPREVE use a guppy friend bag. This washing bag will prevent microplastics from shedding in the water.
