Seaweed Fiber

Our Seaweed Fiber t-shirt is created using saltwater seaweed and organic cotton. To create it, saltwater seaweed is combined with sustainable cellulose, using a method which saves on both energy and resources.

Harvesting the seaweed is a gentle, selective and sustainable process. It removes only the part that is able to regenerate, leaves it untreated and ensures its ecological value is retained. This material was produced in response to the increasing harmful impacts on our environment and after several years of intensive research. The fiber is carbon neutral and 100% biodegradable.

Why is using seaweed good?

Seaweed fiber holds many benefits. It is light, breathable and the fabric feels soft against the skin. One of the most impressive aspects is that the seaweed nutrients are retained in the fabric, which is then absorbed by the skin. This transfer of nutrients is promoted by our natural body moisture when the skin comes in contact with the fabric.

Why is it better than using cotton?

Seaweed fiber is better than cotton due to its heightened ability to absorb sweat much faster. This makes it ideal for activewear, everyday basics, underwear and infant clothing. Seaweed also contains lots of antioxidants that react with free radicals in the skin to neutralise them, which is believed to slow down ageing and reduce skin damage.

How many seaweed/algae species are there?

Currently, there are over 50,000 species of algae and about 12,000 species of seaweed. Knotted Wrack is a wider family of seaweed which encompasses lots of different strains that grow all across the world. Most algae/seaweed grows abundantly in the ocean, which is what makes it such a perfect choice when developing new, innovative materials.

Where is it sourced and how is it made?

The seaweed we use is a brown algae called Ascophyllum Nodossum, also known as Knotted Wrack. It is harvested from the sparsely populated Icelandic Fjords, in locations where there is zero waste and zero pollution from ship traffic.

The fabric is produced using the same method as Lyocell, an innovative and eco-friendly process. Production takes place in a closed loop with zero chemicals released as waste, supporting a responsible manufacturing system. A highly specialized team of engineers and scientists supervise the production process on site at all times. This particular procedure was awarded with the 2000 European Environmental Award in ‘Technology for Sustainable Development’.

The patented process embeds the seaweed firmly within a natural cellulose fiber. This is executed in a specific way to ensure that even after multiple washes, the positive properties of the seaweed are permanently preserved in the fabric. Keeping you fresh for days.
