1. August Society 

August Society is a Singapore-based sustainable swimwear brand that even dips their toe in activewear. They use waste plastic as the raw material for their swimwear, such as single-use bottles, and ECONYL® regenerated nylon fibres. Even using digital printing for all custom prints, to reduce the amount of ink and dye used in the process, the brand works to be sustainable through and through. What’s more, August Society creates multi-use designs that can be worn for swimming and exercise that are reversible and optimal for mixing and matching. From their flexible styles to their majority plastic-free packaging, August Society is keeping swimwear out of the landfill for longer.

4. Vitamin A

Vitamin A is a sustainable swimwear brand based out of California that creates beautiful and luxurious bikinis and bodysuits.

The result was EcoLux™—the first premium swim fabric made from recycled nylon fibres. Other eco-conscious textiles like organic cotton, linen, recycled cotton, and Tencel® have also been incorporated into Vitamin A’s production. And all materials are certified to meet the global Oeko-Tex standard for safe textiles. Most products are locally made in California, however, ones that are not are produced with fair trade artisans that provide women with fair-wage jobs in safe working conditions. Their packaging is also 100% recycled, recyclable, and biodegradable. Vitamin A’s classic and sexy styles are sure to flatter all.
