The Denim Puffer Jacket.
We’ve taken the puffer jacket – traditionally one of the weakest and most delicate pieces of clothing you can buy – and rebuilt it from the strongest fibre ever made. Every fibre on the outside of the jacket is up to 15x stronger than steel, so even if you were wearing a steel-plated jacket that was the same weight, the Indestructible Puffer would be 15x stronger. The material we’ve used is so tough it was originally used in body armour, anti-ballistic vehicle armour, mooring systems for giant container ships, and ropes used to tie down oil rigs in violent, icy seas. In early tests the mooring lines were so strong they broke the machines that were meant to be testing them, and the body armour stopped bullets from a Kalashnikov. So when we went to build the toughest puffer jacket ever created, there was only ever one material we could make it out of. Built to see you down to -40°C the jacket comes in one colour, black. And one mode, tough.
The Indestructible Puffer is made from Dyneema which is the single strongest fibre known to man today. If you’re into chemistry, it’s an ultra-high molecular weight polyethylene that combines extreme strength with very low weight. On a weight for weight basis Dyneema is up to 15x stronger than steel and 40% stronger than high-strength aramid fibres. While it’s often used as a composite – an ingredient added to other materials to make them exceptionally strong – the entire outside of this jacket is made from 100% Dyneema.
To understand just how tough Dyneema is you have to look at how it’s being deployed in the world today. It’s used to make bullet resistant vests, armour and helmets. It’s used in panels on tanks to protect against stronger ballistic threats like anti-tank projectiles. And you’ll find it in bulletproof cockpit doors in most commercial planes in the US. Unlike other high-strength materials it’s so light it floats on water, and it’s resistant to the long-term effects of moisture, UV light and chemicals, which is why it’s now also being used in artificial limbs.
We wanted to create a jacket that could withstand the toughest challenges in the coldest places on Earth. Nature claws at you, hits you and freezes you. So in our testing we exposed the puffer jacket to the shearing, tearing, and blunt-force traumas that you’ll get in the real world from rocks, ice, trees, and falls. Dyneema is so strong this jacket is almost impossible to rip. Blunt-force trauma will have almost no impact on it other than marking it. And our knife slash test shows what damage the sharpest rocks would be likely to inflict.
The colder Dyneema gets, the stronger it gets, which is why it’s used to make the mooring lines on giant ships and deep-water oil rigs that have to perform in freezing seas. A mooring line on a winch buried under heavy ice on a ship sailing in extreme conditions simply can’t fail. As the temperature drops down to -50°C the Dyneema ropes gain 5-10% strength. Projections show that the rope would gain even more strength if it dropped to -150°C. And it doesn’t just get stronger, it also loses no strength in relation to abrasion resistance or cutting.
Most puffer jackets are built to be as light as possible, so the outsides are typically made from super lightweight polyester and nylon. The trade-off for this weight saving is that they are incredibly easy to tear and snag. And once you have a rip, or the seams have started to go, or the tiny spines of down have poked their way through the lightweight outer layer, it’s simply an escape hatch for the feathers inside, and the jackets destroy themselves from the inside out.
