My binos (B&L 7 x 26 ) came with a long shoe string sort of strap. It’s nylon and flat, but thin. I wear it over my neck and shoulder and it lies on my side by my belt, out of the way. The nylon strap slides to let me pull the binos up for glassing and then back out of the way. I tie a loop in the strap if I want to wear them closer, up on my chest for birding and scouting. I’ve looked at different harnesses, but it seems like to much extra stuff. dwc
