Gathering around the bonfire while exchanging fantastic stories about the whole day of hiking is probably one of the best things one can experience in camping. The worst part though is having to sleep uncomfortably in the dark and cold woods. The campfire might be a good source of warmth but because it can’t be kept live through the night, it is best to get the protection from a wind chill from something else, say, a sleeping bag.
A sleeping bag is basically a blanket with a certain extent of thickness and can be closed using the zipper in either one or both of its sides. It functions as a portable bed practically used outdoors. From the time of its first use, the sleeping bags have undergone different transformation in both features and materials used. Chinook sleeping bags, for example, employ the use of better in quality sleeping pads and thermal insulation to provide unmatched warmth and comfort to campers using it.
