Seaweed Fiber T-Shirts

Carbon Dioxide Removal (CDR) is complex

Keel Labs recently announced the Kelsun T-Shirt as its flagship product made from seaweed—70% Kelsun fiber and 30% Cotton blended yarn. The Kelsun T-Shirt also shows off a brand signature with a screen print that uses Living Ink's Algae Ink.

Notably, this first Kelsun garment was made using industry-standard knitting machines. This sustainable fashion design exemplifies Kelsun's potential to effortlessly replace fibers commonly used in the textile industry, reducing the reliance on specialized equipment, resource-heavy materials and fossil fuels. According to the brand, Kelsun can reduce water usage by 70 times and land use by 100% when compared to cotton by utilizing seaweed, one of the most abundant, regenerative and renewable organisms in the world.
