for a little while i wore a BDU jacket with the breast and handwarmer pockets...i filled it up pretty well and it distributed the weight well. it carried some extra goodies that don't fit into my pants pockets that weren't absolutely necessary but were good to have on me, and came in handy once or twice.
i have also carried a possibles sort of bag, usually a small backpack or more commonly a satchel/shoulder bag...aka man purse. i tend to want to fill it up though, and i have a tough time organizing with the bags that i have had. i also like to switch up bags frequently (sometimes i feel worse than a woman with her purses) so i don't like to put too much stuff in the few accessory pockets i have. i have more or less settled on a small pouch with all the stuff in it that i can switch between different bags, but i still have trouble keeping that small and light.
anyways, back on topic...
i have considered after wearing the BDU jacket for a while that maybe something like a basic photographer's or even a fishing vest could be pretty cool for carrying some basic backup gear.
i once read a cool article that a guy wrote about a vest he wore every single day that looked pretty snazzy, he fit alot of neat little goodies in there too. i will have to see if i can hunt that up, it would be cool to read again.
