The main focus is equipment: how to choose the right sleeping bag; what advantage a round dome tent offers; why you shouldn't buy an axe with a painted handle; when fishnet longjohns are better than cotton ones; which snowshoes maneuver best in scrubby areas. The book also includes a chapter on predicting weather, as well as sound tips on safety and equipment upkeep.
