Sustainable Practices




SEPTEMBER the Line’s philosophy is to create elegant and simple surf & swimsuits that allows all women to feel confident in and out of the water and is respectful of the environment and its natural resources. 


We only use the highest quality Italian recycled fabrics to create high-end surf & swimsuits for the modern woman who loves fashion, surf and mother nature.



Fishing lines are a major and deadly contributor of environmental damage to marine life, that take centuries to fully biodegrade.  Not only does it entangle and kill aquatic fauna and flora but it ends up in the seafood we eat due to accidental ingestion.   Our Italian fabric comes from 78% regenerated nylon comprised mainly of ghost fishing nets recovered from our oceans and old carpets. 


The recycled nylon is woven with 22% Xtra Life Lycra®, which is two times more resistance to chlorine and has a UV protection of 50.  Our unique fabric has increased shape retention and higher durability than mainstream swimwear fabric.  And it's sustainable.  We don't think it gets much better than that!  


Swing Tags & Packaging 

Roughly 40% of all trees harvested for industrial use goes to make paper.  The pulp and paper industry is also the largest industrial user of water, the biggest water polluter, and the third largest emitter of global warming pollution in most industrialized nations.  We have decided to make our swing tags from 100% recycled paper card and PVC in order to lighten our environmental burden while also supporting recycling companies.  In addition, the waterproof pouch that encloses each order is made from 100% post-consumer recycled materials.


Hygiene Liners

We believe in sustainability as much as we believe in hygiene – both things are a must.  We are aware of both the necessity to have sanitary protection in sensitive areas of our suits as well as the damaging environmental impact of something that always ends up being single-use plastic.  With both in mind, we developed our biodegradable and compostable hygiene liners to minimize our environmental impact. 



Our factory is family owned and has been operating for more than 15 years.  It uses efficient, eco-friendly, and ethical technologies and practices and provides healthy working conditions for all employees.  All workers are paid a fair and healthy living wage and many work with other family members. 



While we sell our products through stockist in Australia, Bali, and Lombok, the majority of our customers make their purchases through our online site, helping to increase our sustainability.  On average, e-commerce shopping reduces overall carbon imprint by 30%.  We also conduct our advertising, receipts, and newsletters online; this greatly reduces our paper trail as receipt paper cannot be recycled.  


Some scary facts about the use of plastic:

  • 8.3 billion tonnes of virgin plastic have been produced to date
  • Nearly all plastic ever created still exists in some form today - (6.3 tonnes)
  • Only 9% of that waste is recycled 
  • Plastic is found in a third of caught and consumed fish
  • Fishing lines take around 600 years to biodegrade  

This is one of the many reasons why all of our swimsuits are 100% regenerated nylon yarn from old fishing nets.



We always strive to inform and educate as much as possible regarding the environmental damage from our usage of materials and resources.  We always keep our eyes open for organizations that share our values and concerns for Mother Earth; when it comes to saving the environment, we're all in this together.


If you are interested in contributing to saving the environment and don't know where to start, we've got you covered:

  • Surfrider Foundation is a California-based grassroots conservation group, fighting to protect coasts and oceans by supporting water quality testing, community partnerships, volunteer opportunities, beach cleanups, and more. 
  • Designed for both individuals and organizations, the Plastic Pollution Coalition is a network of partners working to understand and solve plastic pollution.  To contribute, each person can take the 4Rs Pledge to refuse, reduce, reuse, and recycle plastic. 
  • Ocean Conservancy focuses on long-term solutions for healthy oceans, wildlife, and coastal communities.  For over 30 years, they have been hosting International Coastal Cleanups that bring together millions of volunteers to remove trash from beaches around the world.
  • Parley for the Oceans has a strategy to face plastic pollution head on: avoid plastic wherever possible, intercept plastic waste, and redesign the plastic economy.  The organization is working towards inventing smarter materials to use in place of plastic, while also reducing the amount we do use until that time. 
  • Greenpeace is a global NGO that works to promote a wide range of environmental issues.  When it comes to plastic, one of their largest campaigns is a global petition to encourage ministerial action against single-use plastic.
