The bivouac bags are often used as a short-term tent replacement for weight savers. The weight is as minimalistic as the comfort. Bivouac with the Ultralite Bivy Should you find yourself in the position of having to set up your camp outdoors, i.e. to set up a so-called bivouac, we have a few tips for you: - First choice in such situations is a bivouac sack. It is windproof and protects you from rain and snow. The reflective inner side keeps the warmth on the body. However, upside down (silver reflective side outside) the bivouac bag can also protect you from too much heat. - Find a place that is protected from the wind. Do not lie down on sloping snow fields. Bivouac sacks are slippery. In strong winds, make sure that there are no loose branches or stones above you. - Never lie down in dry stream or river beds. If necessary, position your legs facing the wind so that the wind cannot penetrate the bivouac bag. - Place your luggage or rucksack next to your face for protection. - Clothing is best kept in the bivouac bag as long as it is reasonably loose and you have enough room. These clothes help to form air chambers, which have an insulating effect. - To warm up the bivouac bag quickly, it helps to breathe into the bivouac bag. - But never close the bivouac bag completely when you are lying in it, because then you cut off your oxygen supply. - Take your water bottle and possibly a snack with you in the bivouac bag. Food and drink keeps body and soul together. A bivouac bag is also an aid for the care of injured people or their transport. In an emergency, simply cut open the bivouac bag and use it as a rescue blanket.
