Might be stupid question but...

Hmm... Caviar leather is supposed to be the most durable, and I generally find that it is very durable. The leather on my bronze Cotton Club seems pretty durable, because it's an aged calfskin, and thick, not flimsy in the least. You should check out the Cotton Club totes IRL, they're great! :smile:
 
My caviar cabas withstands all the torture I inflict upon it and it still looks good. I know my cambon bags even though they are not cotton club have taken beatings.
