In this paper, we provide useful information to choose the sleeping bag you need for each particular output.
MODEL WHAT I NEED?
The first thing is to pay attention to the conditions under which the bag will be used. We suggest considering the climate and terrain as well as the relationship between weight, size and efficiency that will be required.
Each person has a different metabolism and hence a different amount of insulation required. If you commonly sleep with many blankets, it is best to find a bag something warmer than normal for the weather to you head.
There are two values, expressed in degrees centigrade, which accompany the description of the entire bag, it is the approximate temperature range. The first value indicates the lowest temperature at which the bag keeps its interior comfort. Second, information about the lowest temperature at which the model may be used.
The temperature range is the essential basis for choosing a suitable bag. Remember that refers to the temperature outside the tent and not the interior, which is usually between 10 and 15 degrees higher.
Types of bags
Coffin: are the standard for backpackers because its narrow shape in the feet combines a more efficient heat retention in that area and a small footprint to save. Models such as the Zaigón have a width 84cm height and 56cm at the shoulder height of the foot, thereby preventing heat loss which occurs in very loose bags. One drawback worth mentioning that the feet are "trapped" and is less movement possible. Refrain claustrophobic.
Rectangular: offer more interior room to move but have greater weight and volume. Although less efficient in retaining the temperature is lower cost and sometimes have the ability to open and used as blanket, which is not small.
Intermediate forms exist, or modified sarcophagus, which combine the advantages and disadvantages of each format.
MATERIALS
The goose down filling main advantages for sleeping bags excellent insulating capacity, durability and low weight. The bag Softdown , for example, weighs only 0.85 kg. and has an approximate temperature range of between 0 and -10 ° C.
For humid climates or wetlands are the best choice as the bag fills synthetic Standard , still damp maintain body heat. Comparing dry, however, the isolation of synthetic material is less than the feather fillings of high quality.
The type of tissue from the inner and outer fabrics is important when seeking to maximize the breathability of the bag (so that no body perspiration and condensation trapped inside) and its impermeability.
The bag should be provided according to the weather, if the temperature drops a little longer than expected, you can always sleep more coat, but on a hot night no convenient way to adapt if we have a model for very low temperatures.
For more comfort, but especially to preserve the temperature of the bag, it is necessary to have an air mattress or EVA cooling by preventing contact with the ground.
A wide range of models and materials available, so finding the perfect bag for your plan outdoors is not an impossible task.
