Last month in Mexico, Christina and I had finished shooting on this dive and were drifting along in the Cozumel current. She took the housing and shot a few frames of me doing nothing.

Even with water temperature at 81-82F, the hat helps keep the heat in on long dives. I have two; the other one has red air vents that look like horns. The vents release air trapped in the cap and provide a certain amount of comic relief.
