Prince Neptune is an eco-conscious fashion brand founded by Cody Simpson. Conceived with the ocean in mind, Prince Neptune implores environmentally responsible practices and materials across each step of the operation. From the design and fabric considerations - to factory ethics and manufacturing processes - right through to the packaging and distribution services, the brand is intentionally eco-considered to conserve our ocean's resources.


Cody Simpson has partnered with Australian-based product agency Slyletica to bring his creative vision to life. Prince Neptune’s network spans across the globe starting with design in Melbourne, Australia. The agency then works with vetted manufacturing partners from across Asia and Europe which meet Prince Neptune’s responsibility criteria. We look for partners with CSR awards, local fabric and fiber sourcing, and water conservation efforts throughout the process. 

Wherever possible, our garments use locally sourced recycled polyester made from post-consumer plastic bottles. Diverting PET bottles for this process reduces landfill, and thus reduces soil contamination and requires less energy than virgin polyester. According to a 2017 report by the Textiles Exchange, organic cotton uses 91 per cent less ‘blue’ water (from groundwater and surface-water bodies, such as freshwater lakes and rivers) than conventional cotton. 


Our factory partners have implemented a number of initiatives to ensure they go above and beyond the required standards. These include reducing wastage, being 70% solar-powered and ensuring comfortable working conditions for staff. Our Asian manufacturing partners are BSCI certified, which is an international standard for fair working conditions which includes no child labour, no forced labour, workplace safety and health, freedom of association and collective bargaining, working hours and HR management systems.


Prince Neptune mailer bags and protective bags might look like plastic, but they are not! Unlike traditional shipping mailers, our mailers are made from mostly plant-based materials such as cornstarch polymer, an environmentally friendly bio-polymer made from the natural starch found in corn.

All of our packaging is biodegradable and compostable, including the garment bags, and as such our mailers have a ‘home compostable’ certification. Once you receive it, cut it up and put in a home-compost bin. Once composted properly, it takes about 3-4 months to break down into fertilizer for your garden.
