I added two small holders (out of ripstop nylon) to the shoulder straps, one for a small digital camera and the other for my GPS. The holders held the bottom half of the unit and then I had small elastic that prevented the units from bouncing out. I had one piece of elastic going around the GPS horizontally and then came over the top with another piece of elastic and sewed it to the middle of the horizontal elastic. This way I could bend over to pick up my hiking sticks etc., and not worry about the camera or GPS falling out. I only sewed the top of the pocket to shoulder strap. The rest of the pocket was free – worked fine.
