Vitamin A

The founder of Vitamin A, Amahlia, worked side by side with the Patagonia founder and environmentalist Yvon Chouinard, on a design project. It was there that she was inspired to use recycled plastic bottles in swimwear as they did in their technical fabrics. 

When she was told by fabric suppliers that there was “no market” for swimwear made from recycled fibers, she decided to make it happen anyways. Partnering with the top mills in Italy, Canada, and California they created EcoLux™ — the first premium swim fabric made from recycled nylon fibers. Now the company has a whole roster of sustainable high-performance fabrics they call on for their collections including organic cotton, linen, recycled cotton, and Tencel®.
