We will discuss some different types of bags and hopefully shed some light on this often frustrating process. Temperature ratings play the most important role in the decision of purchasing a sleeping bag. Our manufacturers label their bags with a temperature rating. The rating allows the salesperson and the customer to know the minimum temperature the bag can sustain heat. However, the rating is only an estimate and should not be viewed as exact.
Different people have different metabolic rates and generate heat in different ways.
Metabolism is important. However, most people do not know or can not acquire their metabolic rates. Keeping a good diet, along with hydrating the body play an important role in remaining comfortable. A well-prepared packer should have sufficient clothing for any situation. If you do not have the experience to know what is needed, try your local outdoor store and ask for the hiking guru.
