If I was in 25-45 degrees below zero I would want the small ax, loaded .45 caliber pistol, extra shirt and pants for each person, 20x20 heavy duty canvas, a bottle of rubbing alcohol, and a compass.
Th small ax is for choping wood for a fire.
The loaded .45 caliber pistol is for hunting food and eating it.
The extra shirt and pants would be helpful because you can put it over your clothes and stay warm.
The 20x20 canvas would be used for making a tent to sleep in at night.
The bottle of rubbing alcohol would be used to help heal cuts and burns.
A compass would be helpful to find your way to the city or wherever we are trying to go.
