Lifehack #1, use a fly fishing vest

A recent thread on 43Folders Google group discusses how to carry around all your stuff like Hipster, PDA, cellphone, pens, Moleskine, MP3 player, wallet and so on. Usually I carry a bag (which is a sort of Inbox for me as well, more on that later) but while traveling, and generally in the summer, I use a fly fishing vest.
A fly fishing vest has a lot of pockets of all sizes, and you can carry around all your stuff in a comfortable way. You have your hands free and do not have to juggle with a shoulderstrap bag or purse. There is also photographers vest which is well stocked with pockets.
Well, that was my Lifehack #1. Stay tuned for Lifehack #2...
