Mine has a small strap handle near the top. It's kind of on the "back" (the side that faces your back), but it's still near the top.
It's too far down to REALLY be useful - it seems to be just for hanging in a retail store or something - but it can work as a handle if you remember to grab down there.
Does yours have this strap? You might be able to rig something up to it, to extend it up higher, or maybe just velcro it or something so it doesn't flop down.
