no backpack attachment points on my F-1x
I've got two F-2's (one a real oldie, approaching 30 years) and an F-1x. My newer F-2 (within the last ten years) has the D-rings on the shoulder straps, and the O-rings on the back, making it easy to attach the backpack straps.
But my F-1x has no D-rings on the shoulder straps, nor the O-rings on the rear. Makes it very difficult to use with the backpack straps. I bought this bag maybe ten years ago, from a legit dealer. Was there a time when the F-1x lacked these rings? I know I already had the newer F-2 by then, so I was surprised and very disappointed when I first went to use the bigger bag on my back.
Is there any way to get this bag brought up to current standard? It's perfectly OK otherwise.
