Out of all the different binocular systems I've had, my favorites for westside hunting are the S4 lockdown and the RYO ultra light harness. The S4 is nice because it's quiet and keeps the rain off your binoculars with sort of a shell. The downside is that the harness is kind of cheesy and tends to ride up on your back.
The RYO harness doesn't have any case but it can be worn several different ways. When hunting in the brush I set it up to "side saddle" where I have my binoculars tucked under my left arm out of the elements, or I can conveniently put them in the front pocket of my vest and cover them with the flap.
