10 Best Affordable Sustainable Swimwear Brands For Your 2026 Adventures — and Beyond

1. Do Good Swimwear

Do Good Swimwear creates colorful or neutral suits in classic, comfy cuts. The sustainable affordable swimwear brand uses ECONYL, regenerated nylon made from ocean waste like discarded fishing nets, and each suit is designed with timeless shapes, making them easy to mix, match, and love for many summers to come. Adopting a slow fashion mindset, Do Good Swimwear’s pieces are made in a local manufacturer for maximum transparency and minimal waste.

Do Good Swimwear also has quite a few give-back projects: they donate to Trees for the Future (plants trees and focuses on enriching soil), Surfrider Foundation (ocean conservation organization), and Tahanan (women’s crisis center in the Philippines), and Women’s Global Empowerment Fund (micro finance loans for women and education for girls).

2. Kitty and Vibe

Kitty and Vibe is a sustainable swimwear brand that went viral for being the first company to make bikini bottoms based on your butt size, not just your hip size.

Their suits are made from 82% Recycled Poly and 18% X-Life Lycra and are ethically made in a woman-run factory in Bogota, Colombia.

Patagonia uses recycled nylon for their swimwear and some suits are made in Fair Trade Certified factories as well. I have a Patagonia bikini that I bought a couple of years ago and I’m definitely a fan—the fabric is comfy and the suit stays in place when swimming.
