These garments are designed to fit over the cold weather uniform. In hot weather, it may be desirable to use smaller
sized garments. Since an impermeable material is used in the garments, caution must be taken to avoid moisture build
up in the clothing insulation worn underneath the garments. Moisture build up may be reduced in two ways: by adjusting
the inner clothing worn to the outdoor temperature and the activity planned and also by utilizing the closures to permit the
heat build up under parka and trousers to escape thereby reducing the moisture within the insulating layers.
Improper use of these garments can produce heat
exhaustion within thirty minutes of hard work.
