I started off with dumping my helmet cam recording goods in a GP pouch, but even with extra foam, things were still a bit shifty so I made this up. I'd rather have the camcorder upright, but have to do it sideways as shown to deal with the lame AV plug. Top layer is for the camcorder and even has an elastic holder. The mass of wires is a mess, but not sure what else I can do short of cutting the actual wires.
There is a middle padded flap to separate the camcorder from the bottom area where the battery pack goes. To settle down the external wire situation I made a simple velcro shoulder wrap as seen in the last picture. Overall this pouch helps keep the recorder padded and recording without skips even with harsh movements. The latest helmetcam trend seems to be slim full digital recorders now, o well.
