I never use Oak Bays in the rain as I am such a coward. Everything else from eggplant Bays to Darias to little Lily get used. I love Oaky and have sprayed her and bought her an Envirosax. Yet I still check the weather forecast before I use her!
I never use any of my Mulberry bags when it is raining, apart from my Chocolate Antony. I just don't want to take the chance! I personally think you made the right decision to leave your SBS at home today.....
