I'm going to London this week and giving some thought to what to wear. I like to have my hands free for traveling about, up and down on the tube, on and off buses. I've treated myself to a new cross-body bag from Osprey in patterned suede. It's light and comfortable and also, hopefully, of no interest to pickpockets. I like to think that I'm fairly street savvy as I worked around London for years, lugging my portfolio. The only city where I have been very successfully pick-pocketed is Florence. They lifted my bank card and spent to the limit at an up-market men's shop. No wonder the men in Florence were so well dressed!
This design of the bag couldn't be simpler, just a large zipped envelope with an adjustable strap which can be removed to create a clutch. We'll see how it performs once I've crammed it with stuff!
