Steel Blazer
Engineered from the same material as the first SpaceX Starship bound for Mars.

- Constructed with 24% stainless steel
- Lightweight, malleable and soft
- Water repellent on the outside
The 20th century was practically built from stainless steel. From cars, to cities, to skyscrapers. And now it has its sights set on building the 21st century too. Starting with rockets and clothing.
While the human body is not built for the cryogenic temperatures of outer space, stainless steel thrives out there. At about 2.7 Kelvin, or -270°C, its strength increases by 50%, which is one of the many reasons the entire outer body of the SpaceX Starship will be built out of it. The most powerful rocket ever built has been developed so it can not only be reused, but relaunch just an hour after each landing. So stainless steel’s toughness and extreme temperature resistance won it the job. It can cope with temperatures of up to 870°C – allowing Starship to withstand the hundreds of re-entries into Mars and Earth’s atmospheres it’s being designed for.
Back on Earth, it’s taken 4 years of R&D to turn corrosion resistant stainless steel into a jacket you can just throw on. The Steel Blazer is a lightweight two-layered jacket reinforced with 24% stainless steel. Malleable, strong and weather resistant, it comes with a convertible collar you can wear two ways, four pockets, metal detailing, a soft and breathable inner lining, and shoulder construction that looks like overlaid steel plates.

You can wear the collar two different ways
The jacket fastens down the centre with five minimalist metal snaps made by Riri, an Italian manufacturer famous for their high-spec metal components. And we’ve designed the collar so that you can wear the jacket two different ways. To wear it like a normal blazer you can fasten it with any of the lower three centre buttons, keeping the lapels folded down. But you’ll also find two extra buttons concealed behind the lapels that let you button the jacket right up to the neck, converting it to a pointed collar.

Why we chose stainless steel
To make regular steel you combine iron with carbon. Iron on its own is quite flexible as its atoms are able to slide around and slip out of place. But once the carbon atoms are added, they lock the iron atoms in position and stop them from dislocating under stress – and this is what makes steel so strong. We chose stainless steel because as well as high strength, it’s also known for exceptional corrosion resistance. And if you’re going to build a jacket out of metal the last thing you want is for it to rust.

In the cryogenic temperatures of outer space, stainless steel increases in strength by up to 50%.

It’s now the strongest metal we’re working with
While we’re only just beginning to discover the potential of steel in clothing, early lab tests show that adding it in the way we have, increases the material’s strength without adding weight. The material scores high in tensile strength tests – which is the force needed to break fibres when they’re pulled in opposite directions. And it has around double the strength of copper materials we’ve worked with. It also scores high in abrasion resistance tests.
