Made from a material 15x stronger than steel
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.
We’ve made Dyneema Black waterproof
To build the latest version of our Indestructible Puffer we’ve bonded a waterproof membrane to the underside of the Dyneema. It’s this membrane that makes the world’s toughest material weatherproof. And it’s the first time this has been done. Constructed with millions of tiny pores, the membrane allows sweat to escape while keeping rain out. So even if you’re in a snowstorm or a downpour and the Dyneema begins to absorb water, it can’t come through the membrane, so that’s where it stops. All the jacket’s seams are reinforced with heavy-duty bonding to make it fully waterproof.
What this jacket can survive
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 it gets the stronger it gets
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.
In the coldest place on earth, this is the strongest jacket
With winters getting a little crazier, the jacket is built to see you down to -30°C. And if the temperature starts dropping again, the jacket just gets stronger, making it unlike any other material ever created. The lowest temperature recorded at ground level on Earth was -89°C in the Soviet Vostok Station in Antarctica. It’s here that the Indestructible Puffer comes into its own. In the coldest temperature ever recorded, this would be the strongest jacket ever made, and still getting stronger.
Built to work in regular cold too
The jacket is insulated and triple-lined. It’s black as that retains most heat. The baffles are large to reduce the potential for cold spots. And the hood covers most of your face. Try this on indoors and you’ll see pretty quickly that it will do the job you need it to do. Of course, the heat you generate through movement and what you layer the jacket with will always have a profound impact on how hot or cold you feel – explorers pushing hard in the Arctic have been known to strip down to their t shirts. But this is a jacket you can take anywhere.
Why you find Dyneema in survival situations
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.
Dyneema has tethered satellites and pulled up shipwrecks
Instead of using the lightest possible outer layer, we’ve built our jacket from the same material that was used to make the ropes that pulled up the Concordia cruise ship when it sank. It’s the same material used to create a 30km long tether designed to pull a capsule back down from space – despite reaching space it weighed just 5.5kg and only needed to be 0.5mm thick. And it’s the same material being used to create 1 centimetre thick tsunami barriers to stop 20 metre waves.
Why you probably haven’t heard of Dyneema before
The reputations of materials are created over decades of exposure, heavy marketing spend, or moments in history like the Nylon riots in 1945 that created brand recognition overnight. Dyneema has had none of these things. But there’s a difference between how well something performs and how well known it is, and sometimes the best things are secret. Whether it’s famous or not, this is currently the strongest fibre on Earth that you can build a piece of clothing out of.
Earth never reaches Dyneema’s melting point
Dyneema’s melting point is a subject of discussion online as it’s lower than the polyester used in most clothing today, and also the aramid fibres used in military gear. But to put it in context we’d have to return to the Hadean period of Earth around 4.5 billion years ago to find air temperatures that would melt it. The melting point of Dyneema is around 130°C, which is 73 degrees above the hottest air temperature ever recorded on Earth of 56.7°C in Death Valley, California.
What the jacket can’t survive
The short answer is it won’t survive bullets or the inside of a volcano. Yet. This is a puffer jacket designed to perform in the toughest environments and coldest conditions on Earth. But like any puffer it is not built for extreme heat, so don’t fire a flamethrower at it. And we designed it for adventure not for warzones. So while this is the strongest Dyneema ever used in a jacket, it won’t stop bullets. You need more layers of Dyneema for that.
Why normal puffer jackets fail
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.
This is not a lightweight puffer jacket
The Indestructible Puffer is very different to a lightweight packable down jacket, in the same way that climbing into a tank is different from climbing into a car. It’s not going to rip apart after a year or two, or start leaking feathers, and you won’t want to try and pack it away into its own pocket because it will fight you. This is built for the hardest challenges in the toughest places, which is why it weighs 2,000 grams and is built to keep you warm at -30°C.
We use plastic bottles to recreate the warmth of down
The Indestructible Puffer’s insulation is made from 100% recycled plastic bottles. The ultrasoft microfibres are so light and puffy that they trap enough heat next to your body to recreate the warmth of down, without needing to pull feathers out of ducks or geese. And while down will clump and stop insulating if it gets wet, the synthetic fibres will continue keeping you warm even in damp conditions.
How the insulation performs against down
While down traps heat well, it doesn’t breathe well. So it’s not the ideal option if you’re working hard. If you’re hiking, climbing or skiing our insulation will do a better job of regulating your body temperature, as it will breathe better and won’t hold onto sweat. And while down will win on a ‘warmth to weight’ ratio if you’re trying to make the world’s lightest jacket, we’re not. This is an Indestructible Puffer, not a weight saving exercise. The synthetic insulation will keep you just as warm at -30°C, and only weigh a few hundred grams more.
What the jacket feels like
The outside of the jacket feels like denim on a cold day. It’s soft and smooth to the touch, but you can still feel a light grain under your fingers. If you’ve ever come across ultra-lightweight Dyneema used in backpacks you’ll know it feels and sounds a bit like paper. But the material we use is simply a different species. It’s called Dyneema Black which is far stronger and far thicker because it’s spun then woven, and it’s never been used for clothing before. The underside of the jacket next to your skin is soft and lined.
Ultra-durable detailing throughout the jacket
The front zipper is a heavy-duty, two-way zipper, so you can undo the jacket from the top and the bottom at the same time. A large storm flap and brass press studs with a matte black finish help secure the jacket in place. You’ll find adjusters on the inside hem to tighten the jacket at the waist. These are also built from metal, work with a double pincer action, and come with a cord adjuster built from Cordura.
Five pockets built for warmth and stealth
The jacket comes with two large fleece-lined side pockets that are big enough to fit your hands even if you’re wearing gloves, or keep them warm if you’re not. There’s a front pocket large enough for wallets, cards, passports and keys, that’s designed to be accessed quickly even in a blizzard. And on the inside of the jacket you’ll find two more pockets, one on either side of your chest.
Unrippable protection for your head
At the side and back of the hood you’ll find extra-thick, elasticated drawcord adjusters with knotted, rubberised ends to tighten it up. The hood is lined on the inside just like the rest of the jacket so it’s soft against your face and skin. The jacket has a high collar to insulate you in the harshest conditions, and it’s double-lined with a soft, brushed fabric against your neck, nose and mouth.
SIze + Fit
The Indestructible Puffer is designed with a loose fit, with plenty of room for other layers underneath. If you prefer a closer fit, we recommend you go for the size down.
