That does not always work; the outside might have external pockets and you would not want them against your body.

The bag I use has the top hinge on the outside top edge and works very well, it can be held down by a short velcro flap, and the zipper that holds it down properly has two handles so it can be zipped up either way, or both directions at once. The brand was "Oyster" although not marked as such, I bought it in the early 80s at Jessops, the branch in Holborn, London; I replaced the strap as it got threadbare but it's still my go-to bag: certainly got my money's worth.
