We believe leather is the most sustainable of all fashion materials. A single leather bag used for 25 years has a far lower per-year environmental footprint than replacing cheap synthetics every few years. The popular "vegan leather" alternative is largely PU plastic — petroleum-derived and non-biodegradable. Full-grain leather from responsible tanneries is a byproduct of the food industry and biodegrades at end of life.
Buying less, but better, is the more sustainable choice.
