Black Algae Dyed T Shirt
Made with seaweed from Icelandic fjords, and the world’s first black algae dye.
- Dye made from algae waste
- Built with seaweed from Icelandic fjords
- Garment dyed for softness
The colour black is everywhere. From our phones to our cars to the ink in our pens. But black has a dark side. Every black thing you own is likely to contain carbon black – a pigment derived from petroleum. The way carbon black is made isn’t sustainable. Vast tracts of land called tar sands are stripped of all life and vegetation to extract the heavy petroleum, while the production process creates significant greenhouse gases.
So we’re on a search for the new black. And our aim is to reinvent the way in which the colour itself is made using the world’s first dye made from black algae.
Over 5 years of R&D have gone into creating the first ever black algae dye. And we spent more than 6 months finding the perfect blend of materials to combine it with. The Black Algae T Shirt is made from organic cotton, pulped eucalyptus, and brown algae – a type of seaweed harvested from Iceland’s North Atlantic fjords.

Technical Details

The Graphene T Shirt is the lightest and fastest-cooling t shirt we’ve ever built.



Graphene’s discovery was probably the first and last time the Nobel Prize will be awarded for an experiment involving Scotch tape and a bin.

We’ve already built four world-firsts with graphene
The Graphene T Shirt is not our first time working with graphene. In 2018, we built the world’s first graphene jacket. We then spent 3 years working with the National Graphene Institute at the University of Manchester creating the world’s first Thermal Camouflage Jacket – a computer-programmable jacket designed to get us a little closer to an invisibility cloak. Our Graphene Jacket in 2023 brought us one step closer to a graphene skin. And in 2024 our Double Graphene Puffer combined a graphene shell with graphene insulation for the first time.




Graphene is the lightest material on Earth. So we’ve used it to create the lightest t shirt we’ve ever built.

Works for sport, training and life
It’s the build up of the bacteria in sweat that makes your clothes smell, not the clothes themselves. But bacteria can’t grow on graphene – which makes the Graphene T Shirt perfect for your gym bag or every day life. As well as being bacteriostatic, graphene is also hypoallergenic and anti-static.




If you’re looking to reverse engineer superhero gear, graphene is the lightest, strongest, most conductive material ever discovered.



Size + Fit
The Graphene T Shirt is designed for a slim fit. If you’re on the borderline between two sizes, or prefer a looser fit, we recommend going a size up.
