Mike,
I have used a lot of variations on the grip clip theme. I could add tie-down loops, or someone could use these. Either way, it would probably work. I'm big enough that I don't have any trouble with it blowing away with me in it (or just my pack in it). If I leave my bivy and sleeping bag at camp for the day, I just fold it in half and put a rock or two on it (being careful not to tear the Tyvek). I just don't want to risk having a hole in the middle of the night from thrashing about.
Do you think I should add the loops? I could add a disclaimer like "use at your own risk".
Dave
