London-based design lab Esta debuts its first product during London Design Festival 2026, titled The Vertebra.

Informed by tectonics in architecture, the semi-aniline leather bag features an external aluminium frame, serving as an exoskeleton for the piece.

The bag is on display in an exhibition that encourages visitors to touch the piece and share their views on it, specifically asking attendees to vote if they think the frame carries or cages the leather.

Caged or Carried? takes place from 12 to 20 September 2026 at 20 Beauchamp Place, London SW3 1NQ, UK.
