I used this most while skiing since when biking it doesn't allow for the GoPro to angle up far enough resulting in filming the ground. But after reading a few tutorials, just clip the GoPro in up-side-down that way you can angle the camera up as much as you'd like and when editing the video, just invert the video. Easy fix. Now I use the Chesty almost every time when skiing and mtn biking.
I recommend it to anyone.
