Around my neck and under my right arm (left handed). Then my bugle tube does the same over the binos. Sometimes when I move just right my tube bangs against my binos and makes some nice glunking sounds. I've had bulls come in silently just from that.
I got pretty attached to my hill people chest pack. Then I found out they sell a bino pouch that attached to the front. I like this. Even rifle hunting, when I have no handgun I leave my AGC bino bag at home.
Vortex Bino Harness. Its cheap, does the job, fits under a backpack well and does everything I need it to do. I try to keep everything simple. Too much gear hanging off becomes a hassle for me sometimes.
Enclosed chest bino harness. Anything else would be lost or torn up quickly where I hunt. It has to stay slim though. I don't want a full sized backpack on my chest.
FHF and marsupial work for me, even though FHF isn't fully enclosed.
I ran one of the elastic Crooked Horn bino harnesses with their Binoc-Sock for several years. Now, with higher dollar glass, I'm running the Kuiu Pro bino harness. I'll never carry my optics exposed ever again.
