Be prepared for wet, wind, and cold.
Wear fabrics that stay warm when wet (NO COTTON!).
Stay dry. Stay well HYDRATED.
Snack often on quick-burning carbohydrates – sugar.
Carry bivouac gear and know how to use it.
Be attentive to yourself, to your companions, and to the environment.
Do not tolerate the cold or cold extremities.
React early & quickly.
