I purchased a camel pack (small backpack with a water bladder) a couple of years ago and I take it to work or when I go out on the water. It holds my lunch, camera, a small first aid kit, has pockets for a pen, a lighter, my knife, and other misc. items. I can also expand it to include a couple of fly boxes. Its been a great little setup. I have a couple of vests but they would literally be a pain in neck and shoulders once I loaded them up (poor design?).
