With the Rick Young harness, does it stretch when you're on all fours, and allow the binos to drop away from your chest and bounce on the ground, or does it keep them tight against your chest? It looks like it would droop like granny titties, especially with heavier binos, but I have never tried one.

That's the main reason I went to a full on chest harness. I got tired of thousands of dollars worth of optics hanging down and bouncing on rocks when I was crawling around the rocks to get a shot at something.

I also got tired of external lens covers, which were always breaking when they get cold and brittle, or falling off and getting lost when hiking through the brush. The full sized harnesses that completely cover the binos keep every bit of snow and rain off of the lenses.
