Portable Sleeping Bag, You Right Choice for Camping

The portable sleeping bag is designed to protect you from the cold in a dream during campaigns. But depending on how the bag is made, which materials were used in its manufacture, the extent thought you will design a comfortable at these temperatures producer or not.

Let's talk a little about the physiology and heat transfer processes. Sleeping person produces between 75 and 100 watts of heat. For the person of average body type, this means that per square meter of body surface it falls between 47 and 55 W / m2 heat. The generated heat depends on the person of complex metabolic processes, which are influenced by gender, human complexion, his state of health and other factors. For example, a young, rather chubby man produces more heat than the older male, and many more women. In addition, beginning tourists feel cold longer inherent than experienced travelers. Just as people often working outdoors, are less prone to hypothermia than office workers. The general trend is that upon reaching 25 years people usually dense physique more cold-resistant than lean. Heat losses are due to heat conduction surface and air circulation, including breathing.

As you know, the more heat is generated during sleep, the man inside the sleeping bag warmer. Less than or persons susceptible to cold, the more comfortable it will be at lower temperatures. The task of the sleeping bag is to reduce the heat loss due to heat conduction.

Unfortunately, there is no universal sleeping bag that can be used in all conditions, so that it was easy, take up little space and at the same time was low. The main criterion for choosing a sleeping bag is its purpose, under what conditions and at what temperatures you will use it.

By the way, if you are going camping, a portable hanging light and a lightweight waterproof tent can also help you a lot.
