1. RubyMoon

‘Activewear for Activists’. 

‘A social enterprise for women powered by women.’

RubyMoon is a not-for-profit brand using ocean waste to make ethical swim and activewear. They donate 100% of profits into micro loans for women entrepreneurs in disadvantaged communities. In fact, they are the only not-for-profit swimwear company that we’re aware of! 


One of their key pieces, the ‘Yasmeen Rash Vest’ is named after Yasmeen Zain All-Deen, a 27 year old who runs a hairdressing salon in Palestine. She requested a loan to buy new equipment that will cost more than $5,000, and she plans to hire more women. Just one example of the micro loans provided to women in 14 developing countries by RubyMoon.

Baiia promote asking the question ‘who made my swimsuit?’ And they are transparent with their supply chain information.

  • They uphold a strictly no child labor policy with youngest worker being 18.

Key Takeaways:

When choosing an ethical brand to buy swimwear from, keep an eye out for:

  • Transparency around supply chain and labor practices
  • Garments made from non-virgin recycled synthetic fibers (swimwear is unlikely at this stage to be made from more sustainable or biodegradable fabrics) 
  • Inclusive sizing and styles and promotion of positive body image
  • Giving back through supporting social or environmental initiatives
  • Added bonus if swimwear is small-batch made.


And, importantly – enjoy exploring these exciting ethical swimwear brands.
