MECHANICAL PROPERTIES
Size:
It should be possible for a 6 feet tall man to be fully encased inside the
sleeping bag. The bag will be tested directly fbr this.
Dry Insulation:
The basic purpose of the sleeping bag is thermal insulation, that
is.
protection from outside cold.
Soldiers in the field might be exposed to rain as they are sleeping. This is
likely to make the outer surface of the sleeping bag wet. The purpose is to
check whether a wet sleeping bag would transmit more cold to the user.
Wet Insulation:
Water Resistance: Water resistance of the sleeping bag refers to the amount of water that may
seep in when the sleeping bag is subjected to rain. It may seep through the
fabric, the zipper or the stitching.
