hi, I have not yet camped out with just a tarp, bivi-bag and sleeping bag in these harsh conditions, i thought it would be fun or an experience to try it out. What is your advice for sleeping in cold temperatures in England?
I have a tarp and US issue Bivi +sleeping bag system that is supposed to be able to go down to -30 if used correctly so im guessing this should do the job just fine. One thing i wanted to ask about though is my Bivi bag... It has a flap at the top that can go over your head (do all bivi bags have this?), this may sound like a stupid question but is that sensible to have a totally enclosed bivi-bag? Wont air get short in there? and wouldn't your breath condense on the inside making your sleeping bag etc all wet? In the summer i have stuffed this flap down infront of my head so that it was not over my face, is it advisable to enclose the bivibag right up in cold weather? The bivi bag is goretex so does this mean that it is breathable but waterproof?
Many thanks for answering my questions!
