While glassing I may let my binocs hang off my neck, but rarely when hiking.
I like the vero vellini neoprene binocular straps the best though I did get the harness type for the Leica geovids I purchased a couple of years ago
Personally I still prefer the vellini type.
When hiking I slip one arm through the strap and carry my binocs like a shoulder bag, under my non dominant arm ,doesn't matter if you're wearing a chest bag or not, I do at times, but not often.
''Tis what works best for me and I would think it'd be a good system for those of you that wear a chest bag regularly
