I guess if you have Swarvoski El Range, your not going to go with my option, but perhaps someone else out there might, so I will put it out there.
I use a Bushnell Deluxe Bino Strap ($12.89) and then put my $300 binos in a Leupold's Go Afield case ($25).
It is no frills, but works great for how I hunt. If the weather is good, I don't use the case, just throw it in my pack. I am almost always wearing a pack, so if it is raining or snowing I run the chest strap from my pack through the back of the Leupold Case and I am good to go.
