I take this travel pouch of sorts with me on trips, your belt goes through one of the sewn on loops and the pouch rides on the inside of your pants. I keep one card and some cash in my billfold but spread the rest of my cards/cash between that pouch as well my backpack I keep locked up at the hostel.
I didn't go that rout for EDC just because I didn't want to feel it while dancing on my stomach. But they make travel belts and secret pockets I think I'll get a setup for the next rave for my phone.
I used a Hidden Pocket while I was there. Not so much that I was worried about getting stuff stolen, but our passports fit much better inside that, than in my clothes pocket. I didn't want to put it in my backpack to risk getting lost.
That Osprey backpack looks nice, and I would have loved to had a good backpack while there, but it's still a little pricey. Can you, or anyone else on this thread recommend a good sub-$100 backpack?
For the sewing impaired there is this "pocket" thing:
I got one and I intent to try it on my next trip.
