Outside of the jacket made from 100% Dyneema® Black
Highly abrasion and rip resistant
Lined with ultrasoft Polartec fleece

140 years after the denim jacket was adopted by miners, cowboys and labourers, and more than 100 years after the first leather bomber jackets were created for WW1 pilots, we’ve built the toughest utility jacket ever created. Every fibre on the outside of the Indestructible Utility Jacket is up to 15x stronger than steel. The material we’ve used is so tough it was originally used in body armour, anti-ballistic vehicle armour, and ropes used to tie down oil rigs in violent, icy seas.

The fleece-lined edition of the Indestructible Utility Jacket is not just designed for pure strength. We’ve turned it into an all-season jacket by making the outside waterproof, and by lining the inside with soft Polartec fleece so you stay comfortable in any environment. The jacket is constructed with ultrastrong bonded thread, heavy-duty embossed metal buttons, and hidden passport pockets.

The Indestructible Pants are designed for pure strength

Woven with a blend of Dyneema® for extreme strength, and elastane for extreme stretch, the Indestructible Pants are about as close as we’ve got to building a batsuit. Since 2019 we’ve been rebuilding ordinary clothes with the strongest fibre in the world – Dyneema®. Having already rebuilt jackets, puffers, hats, vests and jeans with it, we’ve now brought the same technology to pants. While the Indestructible Pants are just 1 millimetre thick, they’re highly resistant to abrasion and tearing and can withstand a 75kmph fall and drag on concrete.

They’re also crazily stretchy
The reality of most materials this strong is that they’re heavy and don’t stretch at all. But we’ve completely rewritten the normal rules with the Indestructible Pants. We’ve blended 10% elastane into the pants which creates a material unlike anything you’re likely to have worn before. The material comes with extreme four-way stretch, so whatever move you pull the pants will simply go with you.

Built with extreme strength fibres

The other 90% of the material is a blend of Dyneema® and Cordura that creates a balance of extreme strength and comfort. Dyneema® is an ultra-high molecular weight polyethylene that combines extreme strength with very low weight. On a weight for weight basis it’s up to 15x stronger than steel. And Cordura is a densely woven, high-tenacity nylon that’s ultrastrong. That’s why you’ll normally find it in hiking boots and on motorcycle gear thanks to its high abrasion resistance.

What the pants look and feel like
While the Indestructible Pants look like normal pants, they’re not built from the regular materials pants are built from, so they’ll feel a bit different to the other pants in your wardrobe. The material feels more like a highly elastic and flexible softshell, with a really technical and slightly textured face.

How we tested them

To figure out just how tough the Indestructible Pants are, we took them into the lab and beat the crap out of them in a variety of different ways. The tests we put them through were looking for one thing above everything else – extreme strength. So we recreated real-world conditions which would destroy most pants very fast. From blunt force trauma and sudden impact from high speed falls, to the steady grinding down of materials caused by daily wear and tear.

We recreated a high speed fall and drag on concrete
The Darmstadt abrasion resistance test is normally used to assess the durability of motorcycle gear by recreating high speed falls onto concrete. We attach three samples of the pants’ material onto a machine with mechanical rotating arms which hover over a slab of rough concrete. The arms then start spinning as they approach the slab, simulating a high speed fall and 30 metre drag, by slamming the material into the concrete. It’s not a subtle test.
Highly durable against regular wear and tear
While the Darmstadt test demonstrates how the pants perform under stress at speed, it’s important to see how they stand up against wear and tear over time. So we also use the Martindale abrasion resistance test to determine how quickly clothes will break down. A mechanical thumb rubs the fabric repeatedly until the fibres break. The test goes to 100,000 revolutions, the equivalent of a lifetime’s wear. A normal polyester fabric survives 25,000 revolutions. The Indestructible Pants easily pass 100,000 cycles.

Tough enough to survive at 75kmph

We started testing the Indestructible Pants with the machine rotating at 265rpm, which is equivalent to a 45kmph fall and drag. They passed with barely a scratch. So we increased the speed until we got all the way up to 412rpm, which is the equivalent of 75kmph. At this point, the impact and friction caused the first small hole in one sample that was 1cm across. The other two samples were completely intact. This is without reinforced panels or multiple layers. Our pants are a single layer that’s just one millimetre thick.

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.
Built with an Italian mill who specialise in ‘tough’
No one’s ever attempted to make Indestructible Pants before. So we worked with a specialist Italian mill outside Florence who produce fire-proof clothing for the armed forces, full body suits for pro motorbike riders, chainsaw-proof boots, and a material called Shark Skin that’s impervious to hypodermic needles. Their biggest customers are the Italian army and the Swedish police, so they sounded like our guys.

Reinforced and articulated construction

Every critical seam on the pants has been stitched with double lines of heavy-duty thread which are reinforced with woven tape on the underside. And we’ve constructed them with an articulated shape which works with the material to follow the natural shape of your legs whatever way you stretch.

Elasticated and rope tied waist

The pants are built with an elasticated waistband, so they’re comfortable like sweatpants. The waist tightens securely with a rubberised, metal tipped rope. And there’s a zipped fly.

Four zipped pockets
All the detailing on the pants is built to be streamlined, durable and practical. So you’ll find four pockets constructed with concealed zippers which lock into place. There are two side pockets and two at the back. Concealing the zippers behind the same high-strength material as the rest of the pants, means they’re just as protected as you are.
