Make your Rockadi last longer with our tips on Bikini Care.


We’re passionate about ethical sustainability and our first eco-friendly, longer-lasting swimwear collection remains the Bedrock of our brand.

Each piece features the strongest, most resilient Econyl® recycled nylon fabric available, and the collection stays true to the principles of slow fashion with new additions and refreshed styles evolving over time.

We make our swimwear from waste plastic, but don’t think it should arrive swimming in it too. So this product comes in 100% FSC certified/recycled, biodegradable, recyclable, and reusable paper-based packaging.
