What is a wooby? What is a bivy? Thanks.
Saddle Tramo, Thank you very much for the questions. I am consistently suprised about how rarely I get questions. I think part of it is that there is a very macho streak in many survivalists so that unless they will actually die (Excuse me but where do you keep the Israeli bandages? I have a bit of a gunshot wound and could really use one.) I like questions because they show me that someone is TRYING TO LEARN. Any time one person has the guts to actually ask a question there are surely 5 folks who didn't know what was being talked about and were embarassed to ask.
A bivy is a water resistant/ proof bag that goes over your sleeping bag to keep you warmer and dry in inclimental weather. Here is an example of one. They vary in size and exact patterns. Some are just a waterproof sack which goes over your sleeping bag and zips all the way up. Some have a small pole or two to kind of get the bag off of your head. Personally I can say the waterproof sack style bivy takes a little bit of getting used to; though the first time it really raint it is amazing how quickly you will pull the top cover all the way over your head. Unless you are truly clostrophobic (sp) I would say the ones with the poles aren't necessary. The advantage of a bivy sack instead of a tent is that it is much lighter. A bivy weights a couple pounds which is a heck of a lot less than most tents. Also they are a lot more compact.
A wooby is properly called a poncho liner. Here is a picture of them. They are a light quilted nylon/ poly blanket which is quite warm for it's weight and rolls up pretty compact (about the size of the big family sized Campbells soup can) They can in theory be attached by the little strings on the side on the inside of a poncho but I don't recall ever actually seeing anyone do that but I think it was a big thing back in Vietnam. In the last decade or so people just use them as blankets.
As the story goes they are called woobies because you would be cold without it. I bring one to every Army overnight trip I go on. They are great for slipping into your sleeping bag's stuff sack to make it a bit warmer or to put into an assault pack for a mission. In cold weather (below 35ish) a woobie alone will not keep you comfortable but it will be the difference between being somewhat cold and tossing and turning all night and slipping into the danger zone.
