Sustainable One Piece Bathing Suits for Summer

I think I’ve said this before but if this is the first time, I’d like to reiterate that I am a big fan of a one piece bathing suit. Mainly, I just find them to be more comfortable. Overall there’s less fidgeting, less wardrobe malfunctions and less weird tan lines I can never get rid of. I realized when I had multiple DMs with the same question “do you have any recs for a cute one piece bathing suit?” that maybe I am not alone in this personal preference. And after the last year I plan on spending as much time as possible in a bathing suit this summer. There are a lot of really cute sustainable one piece bathing suits so I rounded up some of my favorites here.

Sustainable One Piece Bathing Suits


Summersalt may sound familiar because I’ve been wearing their leggings a lot lately. In fact, I was introduced to the brand years ago, when they launched, and Craig and I shot their first ever campaign in Mexico. What really stands out about their bathing suits is just how comfortable they are to wear. Made with 78% recycled polyamide which is composed from post-consumer materials like old fishing nets, their suits also offer UPF 50+ protection.

Fisch Swim

This is a new to me swimwear brand and I am flipping out over this fish print bathing suit! If I didn’t JUST order a different bathing suit I would be adding it to my cart. FISCH uses ECONYL ® – a 100% regenerated nylon fiber crafted from abandoned fishing nets and other types of nylon waste for their entire swim collection.

My Picks: Ribbed Printed Swimsuit (more sizes here), Shell Printed Swimsuit, Rajalin One Piece

Girlfriend Collective

The brand first known for their activewear made from recycled plastic just launched swim! The suits are made from ECONYL regenerated nylon and have UPF 50 protection. One of my favorite things about the brand is how they show their clothing on different bodies. I also love the simple, classic fit of the Whidbey One Piece.

Hunza G

A friend of mine who has worked in the fashion industry for years mentioned this swim brand a few weeks ago (they became famous in the 1980s for the cutout mini dress Julia Roberts wore in Pretty Woman). I immediately fell for this white one piece (waiting for it to arrive-tbd on the see through factor). Their swim is one size fits UK sizes 6 to 14. Hunza G aims to reduce waste through the entire production cycle of their collection from limited production run to minimize textile waste, using excess fabric to make scrunchies and headbands, and manufacturing locally to reduce its carbon footprint.

My Picks: Domino Swimsuit, Nile Swimsuit

Agua by Agua Bendita

You may recognize Agua Bendita for their incredibly beautiful prints and hand-embroidered details. In fact, each print is hand-painted and then digitized. The brand created the AB Hearts Program which is comprised of 500 female heads of household who handcraft and embroider the label’s designs. In addition, their swimsuits are made from recycled plastic bottles. And their algae tags are fully compostable. They are also committed to slow fashion. Taking extra time in the creative process for design, focusing on creating less and creating better.

My Picks: Limon Embroidered One Piece, Durazno Floral Print Swimsuit


I am a big fan of Madewell’s Second Wave swim. Made with 80% recycled nylon from waste like fishing nets, fabric scraps or carpet they also have UPF 50 protection. Their styles are very comfortable and great for activities (I wear mine surfing, paddle boarding, biking, etc). In addition, they already have some really cute prints and styles for summer.

My Picks: Spaghetti Strap One Piece, Square Neck One Piece

Jade Swim

Made entirely in the USA, Jade Swim uses ECONYL made out of 100% regenerated nylon for the majority of their collection. They also upcycle fabric scraps in the production process to repurpose in a variety of ways and use 100% recycled plastic and biodegradable shipping bags.

My Picks: Contour Scoop Back Swimsuit, Nova One Piece, Trophy Swimsuit

Vitamin A

Vitamin A’s swimwear designer created EcoLux, working with the top mills in Italy, Canada and California — the first premium swim fabric made from recycled nylon fibers. In fact, all of Vitamin A swimwear is made in the USA. I also really like that you can narrow down your search by coverage (I’m a fan of full coverage). I’ve also had a Vitamin A one piece for years (the style is discontinued) and it has lasted through lots of wear, washing, chlorine, salt and sun.

My picks: Leah Ribbed One Piece, Jenna Bodysuit
