I dunked a Fossil and it was a disaster. There was some kind of glue in the seams that melted out and stained the bag worse than it was before.
I can't imagine living in such a cold climate. It was in the 50s today and I was freezing!
I did the same with a Fossil and the lining literally came apart. I haven't really figured out what to do with it yet. I love my Fossil bags so it bummed me out.
