I'm a birkin wanna be owner. Someday I'll be ready--maybe a year or so. However, I"ll likely only own one--ever. Needless to say, I need a leather that lasts. I've reviewed the posts and the leather guide. The Togo seems like a good choice, but this cannot be refurbished?? If that's the case, is the box better? I'll be travelling soon and will have an opportunity to visit a Hermes boutique and want to check out the leathers--but I would like to have one in mind when I go in. In your experience, what is the best leather for durability? Must stand up to rain and snow, and ideally be scratch resistant. Ideally, would also like it to not be too heavy. Thank you!
