Keel Labs unveils seaweed fiber t-shirt

North Carolina-based Keel Labs has introduced the Kelsun T-Shirt, a groundbreaking creation developed in collaboration with environmental advocate Aditi Mayer. This garment, made from Kelsun fiber – Keel Labs’ flagship product derived from seaweed – marks a significant leap in sustainable textile alternatives. It showcases Kelsun’s versatility as a plug-and-play substitute for traditional fibers in the fashion industry.

Crafted using a 70% Kelsun, 30% Cotton blended yarn, the Kelsun T-Shirt demonstrates the seaweed-based material’s adaptability in a jersey knit, a fundamental knit construction. The T-Shirt also features a screen print using Living Ink’s Algae Ink, displaying Keel Labs’ signature Spun K on the pocket.

Climate activist Aditi Mayer, known for her work in sustainable fashion, played a crucial role in bringing the Kelsun T-Shirt to life. Mayer highlights the urgency for the fashion industry to reconsider its fiber choices, emphasizing Kelsun’s potential to address environmental concerns associated with conventional materials.

Keel Labs Co-Founder and COO, Aleks Gosiewski, expressed the launch’s broader significance, stating, “This launch is about so much more than creating a T-Shirt – it’s our mission come-to-life, offering the industry a product that can be produced at scale.”

Leveraging seaweed, one of nature’s most regenerative organisms, Kelsun reduces water usage by 70 times and eliminates land use compared to cotton. By seamlessly integrating seaweed into fiber production using industry-standard equipment, Kelsun becomes a practical solution for textile supply chains, addressing the urgent need to mitigate environmental impacts.
