The same type of heavy duty leather strap Tony Makris of Under Wild Skies uses. Adjustable for a long hang (shown) or a shorter hang depending on your height and preference. Slides out of the way on your back in seconds and stays there when you need to shoot or crawl. Friction of the leather strap keeps it anchored and for added support you can put it through the button down shoulder flap on your safari jacket. Simple and flawless design that someone should have come up with a long time ago.
