The binos I use the most have spent I don't care to recall how many years in a pocket of a game bag. The pocket collects lots of twigs and leaves. They look worn, and should considering the years, but I have not noticed any loss of performance. They're the old Leupold Yosemite 6x30. I use them to spot treed squirrels. I bought a couple pair of the Kowa equivalent for my kids. They're a little better. For someone who is already climbing on their 4wheeler half an hour after sunset, they're good enough.

I don't think I could fit enough snacks in a bino harness.
