Taking my proven hat mounting system and applying it to the RunCam2 camera.
The camera slides right into the built in cradle and automatically locks with a secure paddle at the front. Then the mount clips on to the front of the bill of the hat with the curved part resting against the forehead. The user supplied velcro patch then mates witht he velcro patch on the hat (be sure your hat has this) and the camera is locked in tight all setup to be at the perfect angle to capture whatever you happen to be doing.
User must supply a hook patch of velcro for the back of the mount and this works west with a "tactical" hat, one that has veclro on the forehead area.
