I’ve heard good things about pac-Safe, thats probably the most secure messanger bag money can buy.  Just something to consider: its unlikely that someone will try to slash a messanger bag, they will try to steal the entire thing.  I don’t quite understand how it’s snatch-proof unless it attaches to you like a belt or something. 

60 bucks for a crappy looking bag?

i’d bring a small backpack as a daypack

ideally you would have nothing on your back and be able to roam a place like you walk around anywhere else

if someone wants to steal your stuff it will be gone if they are good and/or crazy

maybe go get an old looking bag that no one would want to steal from you……..

Thanks.  I was actually worried more about the slashing thing.  I will be going to Southeast Asia and not in Europe, and for some reason, I have this image in my head that petty crimes like slashing your bag while riding on public transport occur more over there than in Europe (probably because my mom had her purse slashed discreetly without her knowing it while she was riding a jeepney in the Philippines more than 10 years ago).

What about sleeping on overnight trains/buses in China and Southeast Asia?  I’m planning on bringing my digital camera (and possibly my cellphone and ipod) and storing them in my daypack when I sleep.  If I secure my daypack to a post with a cable lock, will that still be a problem?  I’m not really worried about my backpack since it will just contain my laundry and bathroom stuff.  It’s the daypack that I’m worried about.
