Doug Dickerson wrote a review of Adventure Medical Thermo-Lite Outdoor Bivy Sack 1 person on December 28, 2005
For those looking for an emergency bivy or for someone like myself seeking a lightweight bivy for use under a smallish tarp or poncho, this is what you are looking for. I found the bivy useful in cold weather when used in conjunction with a vapor barrier bag liner inside my down bag (as this bivy is not made of breathable material, although it does have a foot vent and large head end opening). It repacks into it's small stuff sack without force, and should last many outings with careful use as it is constructed with somewhat fragile material, similar to the fabric in FroggToggs rainwear only thinner. Could use a lower price given its high wear potential, but overall its a useful product for me.
