My friend I hunt with a lot has done this since the very first bino harness KUIU made. With that first harness they provided a center strap that would replace the bino cover. Leaving an elastic strap to tuck the binos into. He liked it so much that when they stopped offering the center strap I gave him mine. He’s still carrying his binos that way. Had to be 2011 or early 2012 when we got those original bino harnesses.
Update: bought one, set it up, fits my needs perfectly for new GPO 8x40 range finding binocs! Love the function, weight, size, etc.. I might sew on two 3/8" side release buckles for predator calls.
