I really love my Rick Young Ultra Light harnesses.....I have used one while backpacking with my Nikon SE and Swaro Habicht. And use it exclusively in normal use. I works great while wearing a backpack and weighs only 1oz unlike your binos.
If you use a chest strap on your backpack, make sure the top straps of the RY harness are over the top of your chest strap.
I would not really want to carry a 2.5lb binocular on serious Hiking or Backpacking trip though :eek!:
