About Sis Swim

Sis Swim is the inspiration of four sisters who live for salt air, sunshine, and effortless beach days.

We design timeless, minimalist swimwear for real bodies and true confidence. Every piece is handcrafted in Bali using premium, eco-friendly REPREVE® recycled nylon - soft, durable, and kinder to the planet.

Based in Queensland, Australia, we're a small team passionate about sustainable style that feels good and does good, for you, you sis and your besties.
