15 Sustainable Swimwear to Fall in Love With

Sustainable swimwear for every eco-consciousness babes out there who love the ocean. When buying regular clothes, making the Earth-friendly choices is easy:   just buy vintage or second-hand. You can fill up a whole closet with almost every piece of clothing you’ll need for work and play without any of them being new. There is, however, one place where making the greenest choice can often be a difficult thing and that is in the realm of swimwear and intimates.  

This presents us, planet-minded consumers, with a problem: we know we need to buy these items new but we are also very much aware of the fact that the artificial knits used in swimwear are made out of petrochemicals and use up immense amounts of water and energy during their manufacturing processes.

Lucky for us, swimwear has become one of the easiest garments to produce responsibly thanks both to the wave of environmental conscience that has washed over the fashion industry in the past decade and to the availability of better-recycled knits from which to make sustainable swimwear from such as Econyl. Since it’s introduction more than a decade ago, this knit made from recycled plastic waste went from being a novelty to one of the most sought-after materials by companies looking to satisfy customer demand for sustainable products.

Let’s talk a little bit more about Econyl, since you’ll encounter the name so often on this list: the process for making this knit takes materials such as fishing nets, fabric scraps, carpet flooring, industrial plastic, etc. and chemically breaks them down to reassemble them into nylon. Econyl is essentially trash that has been turned into high-quality fabric that is nearly indistinguishable from newly-made nylon. This reduces demand for petrochemicals, uses less water and less energy all while removing plastic waste from the environment.

The brands that made our list all use recycled materials such as Econyl for their garments and take steps to ensure that every other part of their production process, shipping and retailing is also done responsibly. Many of these companies are small, independent labels that produce styles in small batches to avoid excess waste and hire local seamstresses to cut and sew their pieces in an effort to contribute to local economies. They all eschew the use of toxic dyes, follow fair trade labor practices and take steps to reduce their environmental footprints by using compostable packaging, renewable energy, local production, among other environmentally and socially-responsible practices.

After realizing that there were no recycled knits that would be appropriate for swimwear, Amhalia worked with manufacturers across three different countries to develop EcoLux, a soft and luxurious jersey that is exclusive to Vitamin A and used in most of their pieces. Both Vitamin A’s swimsuits and almost all of their fabrics are made in California.
