the bottom line is this... there is comfort in camp and there is comfort while hiking. you dont get to have the best of both. often you have to pick one or the other. the trick is finding a balance. if you want to save weight at the cost of being cold then your good. just make sure you dont go so far with saving weight that you are dangerously cold. its ok to be uncomfortably cold sleeping. thats acceptable for me. ill take the trade off. but if you are doing this alone as i am then you have to walk that fine line carefully. you really can freeze to death this time of year if you are alone. be careful and good luck.
