OCN WEED® contains innovative seaweed fibres that safeguard the future by saving water - unlike conventional cotton, which requires extreme amounts of water when produced. OCN WEED® contains 30 % seaweed fibres (SeaCell™) and 70 % organic cotton, where the seaweed fibres make the feel slightly softer than cotton. The product is pre-washed, meaning it won't shrink when washed.

Why seaweed? We’re glad you asked! Seaweed is a naturally regenerative resource that grows abundantly in our oceans, meaning no fresh water is needed during the growth stage. All this makes seaweed the optimal replacement for conventional cotton fibres, and it helps us save the planet's precious resource - freshwater - that the cotton industry uses in vast amounts. 

Our OCN WEED® Unisex Sweatshirt isn't just any kind of Sweatshirt. It's a Sweatshirt that challenges the norm, breaks tradition, and leads to climate-friendly alternatives. The Sweatshirt comes in a regular fit. We recommend Women to size down and match with our Power leggings or Energy leggings for a perfect look. 

OCN WEED® is Copenhagen Cartel's own patented product by the meter, which consists of 30 percent SeaCell™ and 70 percent organic cotton.

We have set strict requirements to ensure that we take care of nature in our production. The seaweed that SeaCell™ contains is harvested from Iceland and the different areas are only harvested every four years. This is done to ensure full regeneration between harvests and to preserve the ecological value. The great thing about seaweed is that it is a natural and regenerative resource that is already growing in abundance in the ocean. The seaweed doesn't actually need anything other than the water it's already in.


We recommend that you wash your OCN WEED® product at 30 degrees. It helps your style last longer, and is also kinder to the planet. We advise against cleaning, tumble drying or ironing your OCN WEED® product. The product is pre-washed, which means that it does not shrink in the wash.
