Overinflated air mattresses are hard and uncomfortable. Skiers with big hips should dig a hip hole whether or not it is overlain by fir boughs or an air mattress. Wet socks and innersoles can be dried on a good day by tying them outside the rucksack. On bad days they may be dried against the belly, a method which can also be used at night if necessary; however, it increases the moisture which will be condensed in the bag or tent. Because of the low rate of blood circulation when one is lying down, socks should not be dried on the feet. Sleeping too warm is undesirable. Even though one is not conscious of perspiring, water is always being evaporated from the skin surface. In extremely cold weather this moisture will condense as frost in the outer layer of the sleeping bag, impairing its insulating value and necessitating frequent drying. |
