Choice of materials

We are a team of environmentally conscious consumers exploring innovative materials and more responsible production methods. It is our mission to challenge traditional production methods and consumer patterns. This is the starting point for our approach to material selection, production methods and the certifications we prioritize to have in our value chain.


Regenerated nylon yarn

ECONYL® regenerated nylon yarn is made from recycled industrial waste, fishing nets, carpet scraps, and other recycled post-consumer nylon waste, which is otherwise considered worthless and would have ended up in a landfill or, in the worst case, in the sea.

Our swimwear and activewear are primarily created from ECONYL® regenerated nylon yarn (78%) spun together with elastane (22%), creating durable, stretchy, and soft material and enabling an end product that stays where it must even when moving in it.

Recycled polyester

Clean world oceans, that is the goal of the SEAQUAL INITIATIVE, which, through a global community of NGOs, fishermen, researchers, authorities and private stakeholders, makes an effort to clean up oceans, rivers, beaches and coasts. They have developed SEAQUAL®-YARN, which consists of 100% recycled plastic (polyester). 10% of this is SEAQUAL® MARINE PLASTIC, which is made from garbage from the world's oceans. Also with full traceability.

It is then sorted into different material types. The plastic part is cleaned and converted to SEAQUAL® MARINE PLASTIC at SEAQUAL INITIATIVE approved facilities in Europe. The marine plastic has been collected during sea clean-ups in Europe, the Mediterranean and the west coast of Africa.


Water-saving seaweed fiber

The nets that Healthy Seas collects are delivered to a production facility in Italy, which uses innovative technology to make positive use of the nets' durability. Aquafil SpA regenerates the fishing nets and other nylon waste into ECONYL® regenerated nylon, which is used to create an ocean of ​​new beautiful products – e.g. Copenhagen Cartels.

By recycling the nets, you contribute both to cleaning the oceans of plastic and to preserving animal and plant life under the waves. By recycling existing materials, the production process saves the planet's valuable resources such as water, energy and crude oil. It also helps to lower the overall CO2 footprint.


Copenhagen Cartel patented

Our patented OCN WEED® by the meter is created by mixing SeaCell™ and organic cotton. We harvest our seaweed from Iceland, where we have set strict requirements to take care of nature, and therefore the different areas are only harvested every four years, to ensure full regeneration between harvests and that the ecological value is preserved. The amazing thing about seaweed is that it is a natural and regenerating resource that is already growing in abundance in the sea, which means it doesn't need any other water - other than what it is already in.

Conventional cotton is one of the most used fibers in textiles, but also the one that requires the most fresh water. That is why we have created an alternative material which is water-saving and thus more future-proof, which we call OCN WEED®.

Dedicated to saving the world's oceans, we focus on creating positive change with a community of like-minded people who love the ocean as much as we do. That's why we surround ourselves with passionate and courageous people and brands who want to make a difference and create a better future – both for the planet and for us who live on it.


Our Packaging

Our packaging consists of either recycled polybags or dustbags made from cotton waste and waste material.


Our hangtags, labels, flyers and business cards are all made from recycled and FSC-approved cardboard and paper.

FSC is an international non-profit labeling scheme for wood and paper. FSC certification ensures that products come from responsibly managed forests that provide environmental, social and economic benefits.



It is important that we take good care of our products to make them last longer; Fortunately there are environmental friendly ways to do this. Our products are packed in high qhality dustbags or bags made of recycled plastic. Our dustbags are made from 100% recycled residual- and waste textile materials. We use waste materials from the textile industry to give waste material new life as a quality product.
Cotton is one of the most frequently used, but least recycled types of textiles, even though it uses a lot of our nature's precious resources.


By recycling and using innovative fibers, materials and production methods, we give new life to waste that are normally considered worthless. Most importantly, we help clean our oceans from plastic pollution and discarded fishnets.
