You guys are very Americanized. There is no more free thinking. Attach the strap to the binoculars, place the binoculars in the bag-case and close it with Velcro, leaving the strap outside and passing through the back of the bag cover. You hang it around your neck, shoulder, etc. The bag, though durable, is light. It will not fall off and will be held by Velcro, and the binoculars are actually on the strap. Maybe this is not my know-how, maybe it was conceived by the practical Japanese and is no longer described as understandable.
