Winter Camping -clothing -shelters -cooking -sleeping Clothing When winter camping, dress in layers so you can easily adjust your clothes to regulate body moisture and temperature. Three types of layers are considered normal : a liner layer against your skin (longjohns), an insulation layer (fleece), and a water- and windproof outer shell. Another way to stay warm in the winter is through vapor barriers. The body is always losing water through the skin even when we are Your boots should have waterproof outer shells such as oiled leather not active. This loss is known as insensible perspiration and occurs or plastic. Even though fabric and leather boots may have Gore-tex unless the air humidity is 70%. This insensible perspiration goes on at the rate of nearly half a quart every 24 hours. Since it takes 580 linings, the outer layers will absorb water which will eventually calories per gram to turn liquid water into water vapor, heat is freeze, placing a block of ice next to your foot. Protect against heat loss through your head by wearing a toboggan, continually lost through insensible perspiration as well as through balaclava, etc. Over half of your body heat can be lost through your sweat from any activity. A vapor barrier is a clothing item which is impervious to water thereby serving as a barrier to the head. One saying goes, "If your feet are cold, put on a hat." transportation of water vapor. When worn near the skin it keeps Do not wear too many pairs of socks. If the blood flow to your feet water vapor near the skin. Eventually the humidity level rises to the becomes constricted, your feet will get cold regardless of how many point where the body senses a high humidity level and shuts off socks you have on. Tightening your boot laces too tight will insensible perspiration. This prevents evaporative heat loss and slows constrict the blood flow as well. dehydration. Gaiters will keep snow, rain, etc out of your boots and therefore help keep your feet drier and warmer. Gaiters also add another layer of material around your lower legs to help keep them warm. Sleeping wise Increase the comfort range of your sleeping bag by putting it inside of a bivy sack. Other options include cloth liners, vapor barrier liners or space blanket bags, and doubling up bags. Vapor barrier liners should only be used in temperatures well below freezing. Doubling up bags should only be done if you still have enough room to be comfortable in the bag. You also need to insulate yourself from the underlying snow. Foam pads (Ensolite) or inflatables (Thermarest) work well.Your insulation should be a least 1/2 " thick (two 3/8 " summer pads work well, or use a Thermarest on top of a 3/8 " foam pad). It best to use full length pads so that all of your body is insulated. Going to the bathroom before you go to sleep helps keep you warmer because you use less energy to keep your urine warm. Don't breathe inside your sleeping bag at night. Breathe through a stocking cap or bandana instead. Moisture from your breath will wet your sleeping bag and reduce its insulating ability. If someone happens to wake up very cold and cannot get back to sleep all the people in the tent have to get up and make a fire to keep the person who is cold warm. Bathroom For maximum fecal dispersion, persons should make personal holes as needed. There is no reason for a group's waste to be deposited in one place. Head away from camp. Snow should be kicked over urine stains to prevent the "yellow snow" effect. Toilet paper can be a problem in the winter. Burning it once it has hit the snow is very difficult. You can burn it in a tin can or pack it out. A better idea may be to use snow or ice (although powder snow is difficult to use).
