100 Year Jeans
Woven with high-strength raw Japanese selvedge denim, and the same aramid fibres as body armour.
- 14 oz. raw Japanese selvedge denim made by Kaihara
- Material woven with aramid fibres for extreme strength
- Jeans constructed by Blackhorse Lane Ateliers, London
The first ever pair of jeans were designed to be exceptionally tough – the strongest pants anywhere in the world at the time. So we’ve gone back to the first days of jeans to build them as they were meant to be built.
Constructed with a blend of high-strength 14 oz. raw Japanese selvedge denim and the same ultra-tough aramid fibres as body armour, our 100 Year Jeans are built to outlive you.
To build jeans this strong we’ve worked with world class partners. The denim starts life on low-speed, high-strength shuttle looms of Japan’s most fabled denim manufacturer, Kaihara, before the jeans are hand constructed by Blackhorse Lane Ateliers in London, where every pair is personally signed by the craftsman who built them.
Technical Details
Tough enough to survive 75kmph falls
While raw selvedge denim woven with aramid fibres is insanely tough on its own, we’ve taken the typical failure points in jeans and made them even stronger. We’ve lined the seat of the jeans with a layer of Cordura – a high tenacity Nylon with extremely high abrasion resistance. During lab testing we recreated a 75kmph fall and drag on concrete, and the seat survived without a single hole appearing. The rest of the jeans easily passed at 45kmph too, making these some of the toughest jeans ever made.
Selvedge creates a more durable denim
Selvedge denim can only be woven on low-speed looms called shuttle looms. The looms seal the edge of the fabric, creating a distinctive “self edge,” which is where the word selvedge comes from. And most importantly, selvedge creates a tighter weave, making for a more durable denim. In a world of fast fashion and mass manufacturing there aren’t very many shuttle looms left. And there’s an even smaller number of skilled artisans capable of operating them. But today Kaihara has 200 looms still in active use.
It has the stamp of master craftsmanship
Weaving denim on shuttle looms is a much slower process than making denim using high speed modern machinery, which means it’s impossible to mass produce denim like this. And that’s what gives selvedge the stamp of master craftsmanship. You can spot selvedge denim by looking for the distinct white edges when you roll up the hem of the jeans or look at the ticket pockets. And if you’re wondering what the thin yellow line is that runs through the white selvedge strip on the jeans – those are the aramid fibres we’ve used to make the jeans even stronger.
Our denim is made in the birthplace of Japanese denim
The Japanese city of Fukuyama has become a mecca for denim obsessives. Surrounded by the Chūgoku mountains on one side, and the Seto Inland Sea on the other, its unique climate has produced exceptional cottons since the Edo period. Today, Fukuyama is home to Kaihara, Japan’s top denim manufacturer. Founded in 1893 it started life making handwoven indigo-dyed bingo kasuri – a traditional fabric painstakingly woven on shuttle looms.
