Hi! I'm torn between a Damier & Mono Speedy 25 at the moment, and while I love love love the Mono, what's tearing me away from it is the vachetta, whereas the Damier has the brown leather so it doesn't matter. I live around Boston, and our winters and the amount of rain we get in the spring is unbelievable. This bag would definitely be an every-day bag for me, but if the vachetta will really look bad because of the rain & snow, I don't want to deal with the hassle. Are there any treatments I can do to protect the vachetta? Or is it pointless to try & make the Mono work for me in this weather? Thanks!
