Vollebak Just Made the World’s First Jacket Out of Actual Rock

The first tool any human ever picked up was a rock, and it was then sharpened into a cutting edge on a Kenyan lakeshore some 3.3 million years ago. We’ve since stacked stone into pyramids, castles, and most of history’s great cities. And, yet in all that time nobody has managed to ever wear the stuff (for obvious reasons, of course).

Vollebak, the London experimentalists who’ve already built jackets from copper, wood, and mycelium, finally cracked the stiffness issue with their one-off Rock Jacket.

The breakthrough came from Steven Leprizé, a French experimental cabinetmaker whose Paris studio, ARCA, made its name making wood do things that wood shouldn’t. His WooWood technique bonds hundreds of tiny wood tiles to a rubber membrane, creating marquetry that stretches and twists. Vollebak originally rang him about a wearable version of its Wooden Jacket prototype, and he countered with the same trick, but pulled off in slate instead.

Slate was the unlock because it naturally splits along its cleavage planes, yielding sheets a scarcely believable 0.5mm thin. Leprizé’s bespoke cutting machine slices them into 5mm squares, roughly 54,000 of which cover this jacket, and each one is bonded to neoprene with an adhesive cooked up alongside 3M engineers in Switzerland. All in, the material takes 50 steps to produce.

Turning that material into an actual garment was beyond challenging. Stitching slate was clearly never going to happen, so the seams ending up being visibly taped. This causes the surface to flex more like a watch bracelet than a fabric, which also ending up ruling out anything tight or heavily gathered. Vollebak settled on a minimalist cropped Harrington with Cordura pockets and a zip, cutting its panels from five full sheets of Leprizé’s slate.

The neorprene itself comes from a UK supplier whose core business is fetishwear, because, as Leprizé cheerfully notes, rubber meant to sit against bare skin has to be the good stuff.

Nobody at Vollebak is even pretending that this version is practical. It was built as a proof of concep, similar to the Wooden Jacket. And Leprizé is already developing granite, marble, sandstone, and schist versions of the material.

Depending on which interview you read, a production version is anywhere from two years to a decade out.

There’s exactly one Rock Jacket in existence, and Vollebak has it listed at $50,000 alongside a field inviting you to enter your own bid, if that number feels negotiable.
