Does such a thing exist? And if so do you know where I can buy one. I need a handbag I can just sling on my back so I can be hands free as often I will, at the last min, decide to run/scoot/cycle the school run, I also walk lots and lots (up to 10 miles a day) and don't want to be faffing changing my handbag over every time. I want something that looks good, I don't mind fun too.
Can you help?
