Sashiko Jacket
Reinforced with 1 million high-strength stitches, using the ancient Japanese art of sashiko.
- Material made in Japan
- Reinforced with 5.5km of meta-aramid thread
- Built from 100% high-grade jacquard cotton
Reinforced with 1 million high-strength stitches, the Sashiko Jacket pioneers a completely new approach to creating highly durable clothing, inspired by the ancient Japanese art of sashiko. The technique of sashiko, or ‘little stabs,’ is a highly resilient form of embroidery developed during the Japanese Edo period, where worn out garments were repaired using decorative hand stitches. Clothes would be mended again and again as they passed down the generations, getting stronger as they got older.
Rather than waiting until an item of clothing needs to be repaired, we’ve simply applied sashiko-style stitching in super-strong meta-aramid thread over the entire jacket at the start of its life. By combining high-grade jacquard cotton with 5.5 kilometres of high-strength stitching, we’ve created a jacket that’s as soft and comfortable as it is tough and durable.
Double Graphene Puffer
Engineered with graphene on the outside, and graphene on the inside.

Technical Details


The Double Graphene Puffer is engineered with a graphene shell and graphene insulation.


While it’s completely invisible and only a single atom thick, graphene is the lightest, strongest, most conductive material ever discovered.


It keeps out snow and wind while staying breathable
The outer shell is treated with a water repellent coating that helps water roll off its surface, while the graphene membrane in the middle prevents water from passing through. It means the jacket can cope with wind, snow, and rain showers. The only weather it’s not built for is heavy downpours. At the same time the membrane allows sweat vapour to escape from the inside, helping to prevent you from overheating when you’re working hard.


In 2018 we built the world’s first Graphene Jacket. Then in 2022 we used graphene to bring us one step closer to an invisibility cloak.


The puffer’s insulation is infused with graphene, which conducts heat better than any material on earth.

The graphene conducts heat and warms you up
Graphene conducts heat better than any material on Earth. So when you’re wearing the jacket in cold weather it helps equalise your skin temperature by sending heat from the hot bits of your body like your head, to the cold bits like your hands. It’s the first wave of conductive fabrics that will carry heat or electricity around your body but without any power source. Lab tests have shown that the closer to your body the material is, the more effective it will be at regulating your skin temperature and increasing it by an average of 2°C.







Graphene’s discovery was so mind-blowing it was compared to finding CERN’s Large Hadron Collider on your desk.
