I found a great little side bag for my pocket wizards today. It was EXACTLY what I had been looking for. I have several pocket wizards and all the cables, but no way to carry them, sometimes I want them, sometimes I dont. I wanted a bag I could connect to my main bag when and if I need them, and if not detach and leave at home.
The girl at the camera store showed me some of their other products, I was really impressed. It is a company that was started by photographers and they have a number of very innovative products. (Most of these camera bags do not look like camera bags, intentionally).
I bought the Pocket Wizard pouch (it was like $35), its very well constructed, smartly designed and comes with a full lifetime warranty. Think Tank Photo Gear
