British clothing brand Vollebak has introduced its latest material experiment, the Rock Jacket, a one-off prototype garment constructed from thousands of miniature slate pieces. Having previously worked with copper, wood, aerogel, and electromagnetic shielding, the brand reaches further back into the material timeline by turning solid stone into wearable, flexible outerwear.
The jacket's surface features thousands of 5mm x 5mm slate tiles mounted on a neoprene backing, forming a grid that twists and bends while retaining the uneven texture of natural stone. From a distance, the garment resembles pixelated armor, while close inspection reveals the detailed layers and natural variations of the slate material itself.

The material was developed in collaboration with French designer, material technologist, and experimental cabinetmaker Steven Leprizé. Vollebak approached him to explore a wearable successor to their earlier Wooden Jacket. Leprizé adapted WooWood, his elastic marquetry technique that bonds small wooden tiles to a flexible rubber membrane, substituting timber with thin squares of slate.
Transforming rigid geological materials into a flexible textile represents an advanced intersection of material science and fashion engineering. By bonding stone onto neoprene with laser-cut precision, the design bridges architectural elements with everyday apparel, pushing the boundaries of wearable experimental prototypes.
Production begins with slate sheets measuring 100 x 50 cm and just 0.5 mm in thickness before being cut into half-centimeter squares. According to Leprizé, the fabrication involves approximately 50 distinct steps, where precise cutting ensures the grid moves cleanly without sacrificing the distinct visual character of the stone.

Vollebak fashions these flexible sheets into a cropped, minimalist Harrington jacket silhouette. The slate panels are laser-cut and joined with visible taped seams, contrasted by functional Cordura pockets and a conventional zipper. Currently existing as a unique one-of-one piece, co-founder Nick Tidball views the design as the beginning of an ongoing investigation into rock as a potential construction material for clothing.
