I have been using the hooped Bibler bivy for several years now and I could not be happier. I have used it on many a backpacking trip as a great alternative to a tent, although it means you partner needs one as well. I have also used it at the base of many a climb for a lightweight bivy set-up that has never failed to deliver a great night's sleep. I have never had condensation issues and the material has held up admirably so far, as long proper care is taken. I have slept several nights on a portaledge in it with no problems what so ever. And I have endured more than a few rainy nights with no leaking. Although, if extended weather (more than one night) is anticipated, I would gladly carry the extra weight of a tent. Try talking to your partner, shouting through bivy sacks in a storm.
