FedEx just delivered my GST with silver! Of course, I immediately put all my stuff in it and it fits very nicely with all the compartments. But for those who have this bag, I have a few questions: does it soften up a bit? The straps slide off my shoulder a little and I am hoping that with wear, it will conform to my shoulders. Also, with wear, I am hoping that it becomes a bit less rigid. I have been wearing my cabas which I think is almost the opposite of this bag, so it may take getting used to. Any answers or advice, experts?
