Oops. I don't mean the underarm stabilizer strap. I mean the main strap. When it is fully strapped down I have a large piece that flies everywhere. I don't like to use the plastic thing on the strap to shorten it, because then I have to make it longer when I take the bag off. I was thinking a large carabiner to clip the end of the strap to the D-ring, but I don't know where to buy a large one.
