What every piece is made from, and why we chose it.

Black vegetable-tanned horse leather

Horse Leather

The hide, and why it's ours — supple, strong and light, sourced as horsefront and vegetable-tanned in Tuscany.

Leather being cut by hand in the studio

Vegetable Tanned Leather

Made for us at Conceria Maryam in Santa Croce sull'Arno — developed and tanned to our own specification, not bought finished.

RiRi zips

RiRi

The zip standard since 1936, made in Mendrisio, Switzerland — and why it still runs smoothly after ten years.

Hand-forged blued steel hardware

Hand-Forged Blued Steel Hardware

Forged, not cast, by an independent blacksmith — and why that difference shows up years later.

Waxed canvas weave

Waxed Canvas

Where we use it, why it sits alongside leather in the larger pieces, and how it wears in.

Paper patterns in the studio

Care

Less is more — how to clean, condition and restore a piece, with the specific products we use ourselves.
