Recycled & certified materials

We know that efficiency alone is not enough. The world needs systematic change to a greater degree and to meet this change we must develop how we interact with nature. We must cooperate rather than compete. And we need to start looking at waste as a resource and adopt a more circular mindset. We believe that the future of innovation is sustainable innovation.



Every year more than 12 million tons of plastic ends up in our oceans. That is a truckload of waste every minute. With that said, all of us need to change how we interact with nature and find a more innovative approach of using resources.

In 2018 we created our own OCEAN-SHELL®-fabric. The OCEAN-SHELL® is a three-layer fabric made from recycled PET bottles collected from the ocean outside of Taiwan. The fabric is equipped with a hydrophilic membrane, which is also made from recycled PET from the ocean. This makes the fabric a full circle renewable source adapted to be recycled again.

From the OCEAN-SHELL® fabric, we create our winterized rain parka Arch Jacket and Sarek Parka which is a high-quality winter jacket for cold days. Both are waterproof and breathable and free from fluorocarbon. They are made in minimalistic and timeless design but with all the benefits from a functional outdoor jacket.

1.Collecting plastic from the oceans

With OCEAN-SHELL® consumer plastics and bottles from the oceans around Taiwan is collected to be recycled.

2. From pellets to yarn

PET bottles are made in a very strong material and are extremely suitable to bring back to a circular process. The collected PET is firstly cleaned and transformed into dry pellets. From dry pellets, it is possible to melt and spin the new polyester yarn.

3.Creating OCEAN-SHELL®

The recycled polyester yarn is then ready to be transformed into Tretorn OCEAN-SHELL® fabric. It is a layered fabric with hydrophilic membranes making the fabric waterproof, breathable and since it is all made out of PET, it is circular and recyclable again.

Ocean Net

Fishing nets are considered to be one of the biggest environmental threats in our oceans. 650.000 tons of fishing nets are left as debris on the bottoms of our oceans, dumped by the fishing fleets. They then drift with the wind and currents for years as “ghost nets”. Eventually, they can end up on a reef where they can knock out entire ecosystems. Ghost nets are considered among the greatest killers in our oceans. Approximately one million seabirds and one hundred thousand marine mammals and turtles die each year due to debris in our oceans.

But fishing nets also happen to be made of some of the best nylon materials in the world. ECONYL® is made out of recycled fishing nets, collected to prevent ghost nets in our oceans and at the same time deliver a premium product of the best quality to the conscious customers.

Ocean Net is a unique sustainable fabric, mixing organic cotton with ECONYL® - regenerated nylon from fishing nets and consumer waste found in the oceans. It is a waterproof and breathable material.

1. Rescue

The ECONYL® Regeneration System starts with rescuing from landfills and oceans all over the world. That waste is then sorted and cleaned to recover all of the nylon possible.

2. Regenerate

The nylon waste is recycled right back to its original purity. That means ECONYL® regenerated nylon is exactly the same as virgin nylon. After the waste is collected different types of waste are cleaned and prepared for regeneration. As part of the cleaning process, materials other than nylon are removed and sent to other supply chains.

3. Remake

ECONYL® regenerated nylon is processed into textile yarn that is later on made into jackets. One of the best things with regenerated nylon is that nylon has the potential to be recycled infinitely, without ever losing its quality.
