well, today I tried carrying my backpack in the front and it was really uncomfortable. Any recommendations on a backpack that has some sort of security so that the zippers cannot be opened that easily? I did see someone with a backpack that had 2 sets of clips over the zippers so it would be a bit challenging to just open it up.

I know it's just a phone but i'm still out about $150 which is what it will cost to replace it and more than the cost I feel really stupid about my carelessness so that is causing me to be even more depressed.

To add to it I also put my passport in that same pocket and the thief did not take my passport so I dodged a really big bullet here, holy crap!

This seems ridiculously stupid in retrospect but I have no idea why I made such an obvious and glaring ERROR being an experienced traveler, that is what bothers me a great deal.

To give you some background, I've been traveling the last 6 months, been to 14 countries and dozens of different cities, on ferrys, buses, airplanes etc. I'm usually very cautious, watch my stuff like a hawk and never once had any issues. This is the VERY LAST day of my trip...I head back home tomorrow, perhaps that is why I was getting a little bit relaxed, so it's particularly depressing that my long exciting trip had ended on a bad note.
