I know you aren't supposed to take damier azur and mono bags out in the rain/snow, but I was wondering why?? I know the material they are made of isn't supposed to get wet, but what happens if it does? Sorry if this is a stupid question!
The vachetta the leather trim on Mono and Dam Azur will get wet and a watermark will remain. Everyone has an opinion on the vachetta and for myself it is the reason I don't do Mono. It develops a lovely patina over time but is a constant change.
I think it just depends on how wet the leather gets. Mine have gotten wet, and the leather is still even. None of my bags are water stained. But I don't go and soak my bags, either... I hope that helps.
