So, other than keeping aware at all times and never looking like a distracted, confused tourist (fumbling with a ticket machine for a train, texting while waiting in a line, or looking at a map while standing in the middle of a piazza), what can we do? There are lots of security devices for travelers. The leg wallet is something I thought might work for keeping extra cash, the emergency credit card or our passports. When I got it I was amazed at how well it fit... sort of like a snug sock. I'm certain it won't slip off. There are two zippered compartments that can fit a decent amount of stuff. My wife also had a teeny bra wallet (a satin sack to hold a couple of cards) but this leg wallet will work for most of what we need to secure. To be honest, the bra wallet was pretty useless since I held pretty much everything safely in my leg wallet.
UPDATE: The leg wallet was a great way to secure three passports, extra cash and a couple of back-up credit cards. It never slipped down my leg and as long as I was wearing long pants, no one knew I had it on. It was much better than the money belt wallet I also brought, which I never used. My only complaint was that on very hot days it tended to chafe a bit on the top end where its elastic was.
The Pacsafe (there are smaller and larger models) is designed for safety. The strap has a wire in it so it can't be cut. The strap also has locking latches which are easy to open, wrap around a table leg (as you are having lunch) and lock again. Most of the zippers can be locked. The fabric is tough, water repellent and cannot be cut with a razor. Inside there is a compartment that has RFID protection. If you don't already know (we recently learned about it), lots of credit cards and passports now contain a chip "for our convenience" so we don't have to break a sweat by swiping a card... just sort of wave it, or recently, sticking into a slot and waiting even longer for the transaction to be completed... yea right. For $100 a thief can buy a scanner, plug it into a laptop, put the whole thing into a messenger bag and scan people's card info within 3'... sometimes further. (What are they thinking? Just because you CAN doesn't mean you SHOULD build these things!) RFID protection is a shield against this (although I heard that wrapping your cards and passports in aluminum foil works just as well).
This bag holds a lot but the water bottle pocket on the side was a bit snug for our tall Thermos brand bottle. Still, it is yet another barrier against the filthy, sticky fingers of little thieving kids and bogus priests alike.
UPDATE: For travel, Lisa thought the bag was heavy, bulky, unattractive and she couldn't find things inside easily. Personally, I think she missed her good old mule bag, which was actually a tad bigger. Also, she might have thought it was heavy because at times she was carrying an extra water bottle--something that I couldn't fit into my messenger camera bag (which itself was always overloaded with most of our tech stuff).
UPDATE: I wound up not using this strap for my camera. Instead, I used a hand strap which I prefer for shooting... the camera hangs onto the end of my hand as an extension of my arm. Much less likely to tangle when putting the camera back into the bag. Remember, I'm a pro shooter and just happen to like having my camera attached to the end of my hand. If you are used to straps, this is a great product.
UPDATE: We did use this lock all the time when hanging out in train stations. We'd cable all the bags together and huddle around them, putting the bags against a wall. The cable lock made it less likely that anyone could actually snatch and run off with a single bag.
