My other bags are lined in Chevre, and now that I've got a Bolide lined in what feels like a baby's bottom I'm wondering how to protect the lining. The biggest potential offender is my set of keys, currently on a keyring and stuffed inside a Le Sportsac zippered pouch. This in a rather inelegant solution, so I'm throwing this question out to all of you. I realize that I could use one of the bag liners, but in a 31cm Bolide it seems like overkill. Any great Hermes Key holders out there?
