Most jackets are not famous. But our original Full Metal Jacket is. Made from over 11 kilometres of copper it has won TIME Best Inventions and even made its own special guest appearance on the Joe Rogan Podcast. Now we’ve taken the Full Metal Jacket, added even more copper, and turned it into the Full Metal Puffer.
 
Copper is one of the most advanced materials in our solar system. Thrown out of supernovas billions of years ago, it became central to the rise of civilisation, creating tools and sterilising water, before enabling modern day communication, transport, and electrical power. We started experimenting with it as we looked for material that could become a building block for intelligent clothing, while offering us disease resistance on Earth and up in space.
 
To build the Full Metal Puffer out of 60% copper, we start with electrolytic rods which we extrude like spaghetti to make strands so thin they have to be measured by lasers and can only be seen with a microscope. We then apply a series of very thin coats of lacquer to protect the copper from corrosion, cure the material for 6 days, and weave it on rapier looms before scouring, heat-setting and drying. The result is a jacket that warps and ripples in the light, and looks like CGI even when you’re standing right next to it. The Full Metal Puffer is also built with an advanced waterproof and breathable membrane that can open and close to respond to different weather conditions, while remaining permanently waterproof and windproof. And it’s packed with 100% recycled 700 fill down to keep you warm in sub-zero temperatures.
