The problem was that the OP was being quite rude at rejecting the advice of a number of experienced backpackers who have, at one time or another, tried using a stand-alone bivy and very promptly quit doing so, for the reasons we have cited. He doesn't have to take the advice, but at least he could be polite about it! I for one suggested several pages ago that he just buy the bivy, try it out and return it to REI if it didn't work for him, but that didn't stop his rather rude posts. This thread has gotten nowhere in three pages, why don't we put a stop to it?

I can just imagine the kind of response the OP will get on BPL if he takes the same tone he has here! I'm a BPL member, so I won't have to imagine it if he does go there.
