For a generation the Basic Essentials series has been as much a part of the outdoors experience as backpacks and hiking boots. Information-packed tools for the novice or handy references for the veteran, these volumes distill years of knowledge into affordable and portable books. Whether you're planning a trip or thumbing for facts in the field, Basic Essentials books tell you what you need to know. Discover how to protect yourself from core heat loss while you're outdoors in any season, recognize the physiological effects of the cold and adapt so you can enjoy yourself safely, distinguish between rapid onset and slow onset hypothermia, use the most efficient techniques to re-warm and treat a hypothermia victim, and clothe and insulate yourself properly for the travel you undertake.
