When you really need them, and you'll probably use them(more) - Vanguard Optic Guard Binocular Harness

Carrying optics has always been a chore for me. When you have expensive and fragile equipment, what you don't want is damage. So you pack it or pouch it. Out of sight out of mind. Pun intended. This harness puts the glass tight on chest and out of harms way, hands free. You don't have the weight of the strap on the back of your neck, no dangling into stuff swinging around. It's quick to spot something, let go, and move. I use only a small glass on mine, a M24 Fujinon. You can pull or slide the glass to your liking. When on a low crawl it stays put. Forget a flat crawl. You might want to make release clips or something to remove the glass from the harness anyway as it comes without. Take time to adjust it and practice using it. Good for your kit. Good Luck.
