For the last 5 years we’ve been experimenting with different ways to make colour that reduce the industry’s reliance on petroleum-based dyes. We’ve worked with everything from the world’s first black algae dye, to wood and blueberries, minerals like celadonite and hematite, and even DNA.

One of the most interesting places to look for new ways of creating colour is in the by-products of other industries. And every year millions of tonnes of almond shells are left to rot or set on fire to get rid of them. So we decided to use them to garment dye a collection of ultrasoft chillout gear instead.

There are five pieces in total – a t shirt, a hoodie, sweatpants, sweatshorts, and this sweatshirt. Every piece is garment dyed in a giant bath of almond shell dye to make them ultrasoft. It only takes about 450 grams of pigment to dye a single piece of clothing. Which is around 150 individual shells. And not too surprisingly they come out the same kind of colour as ground-up almonds.
