Go Pro Hero HD Chest Harness.

This photo shows the Go Pro Hero HD camera mounted to the chest harness. At the left notice the buckle which snaps into the housing. Also seen near the bottom of the front mount are the adhesive tabs I've used to get the vertical angle up while riding the mountain bikes, since the camera will still aim downward slightly even adjusted at it's highest angle. These tabs are on both sides behind the plate, about 1" thick.
