It also appears some photos that the lower buckles might be to far back. In other worlds doe it interfere with your shoulder straps on your pack? It looks the shoulder straps would come right over the buckles possibly digging into your side with a pack on.
From sg holmes IG. That side buckle is squarely under the pack strap. My fhf and marsupial harnesses don’t go under the pack straps. Looks like you’ve gotta start feeling that dig into your ribs after a while?
