CLOTHING AND INSULATION
You can use many materials for clothing and insulation. Both man-made
materials and natural materials, such as skins and plant materials, are available and offer significant protection.
Animal Skins
The selection of animal skins in a survival situation will most often be limited to what you manage to
trap or hunt. However, if there is an abundance of wildlife, select the hides of larger animals with heavier coats and large fat content. Do not use the skins of infected or diseased animals if at all possible. Since they live in the wild, animals are carriers of pests such as ticks, lice, and fleas. Because of these pests, use water to thoroughly clean any skin obtained from any animal. If water is not available, at least shake out the skin thoroughly. As with rawhide, lay out the skin, and remove all fat and meat. Dry the skin completely. Use the hind quarter joint areas to make shoes and mittens or socks. Wear the hide with the fur to the inside for its insulating factor.
Plant Fibers
Several plants are a source of insulation from cold. Cattail is a marshland
plant found along lakes, ponds, and the backwaters of rivers. The fuzz
on the tops of the stalks forms dead air spaces and makes a good down like
insulation when placed between two pieces of material. Milkweed
has pollen like seeds that act as good insulation. The husk fibers from
coconuts are very good for weaving ropes and, when dried, make excellent
tinder and insulation.
