Ladies, my upper back and shoulder are suffering at the moment and carrying a heavy bag is just not helping. I'm looking for something lighter weight for the days when the discomfort is worst. I like a bag I can wear on the shoulder, a secure fastener and probably not too big as I'm vertically challenged. I thought about medium mitzy hobo but thats probably as rare as hen's teeth. A hayden is a definite possibility but I've no idea how heavy or light they are. Any suggestions?
