Materials
Recycled aero-grade aluminium and full-grain leather.
The shell
Ribbed aero-grade aluminium, recycled, brushed by hand. The ribs are structural, not decorative — they are what let a thin shell take the load of a full case without flexing.
The interior
A lined interior with a flex divider and compression straps. No zips on the shell to fail — the case closes on latches.
The leather
The duffle and the small accessories are full-grain leather, the layer that keeps the grain intact and takes a patina rather than flaking. It will look different in a year. That is correct.
