I have use two types of bino harness syestems, the Solo hunter and Marsupial gear
Both strap to your chest so they are close to your body, so if you are on your hand and knees they don't get in the way, they protect your binos from the rain or scrub
Both harness have a lid with magnets, so when you open the harness the lid stays open out of the way, until you need to put your bino away, I found this system works without any issues
I have attached a additional pouch to the side of the harness, so that a gps or a range finder can be accessed easily. Marsupial gear made a pouch specifically for the Garmin Rino
Anyway, I found these two types of bino harness system works well, they make carrying/protecting/using your binos easy. Well worth the money
Cheers
