Fabric & Care
Made from recycled polyester and spandex — soft, chlorine-resistant, and built to last trip after trip.
Care guide:
• Hand wash or machine wash cold (delicate cycle)
• Do not tumble dry — lay flat or line dry
• Do not iron
• Rinse after swimming in chlorine or salt water to extend the life of your swimwear
Sustainability
Every Castaway Reef piece is made from recycled polyester and spandex — giving ocean-bound plastic a second life.
Our packaging is fully recycled and plastic-free. Our factory is certified ethical, pays workers fairly, and holds all relevant sustainability certifications.
We believe swimwear should help protect the waters we swim in — not pollute them.
