I also have this GORGEOUS bag in tobacco and I have not done anything to it! I was thinking of using Apple Gard Rain and Stain spray - it's a great product that I've used on my Chloes, Fendi spy and other leathers. Even Balenciaga bag owners use it on their light-colored delicate leathers. But there might be a chance of the beautiful color darkening. So I will leave it be and let it dry out if I get caught in the rain with it.Ooh, this is what I've been looking for! I've got one in the tobacco color and I've been wondering if carrying it in the rain will harm it? Is there a way to waterproof it?
