The choice of sleeping bag or can ruin your camping. A summer bag for the winter is too cold in winter and a bag is too hot for the summer. There is no single general purpose sleeping bag. You must make your choice wisely.
Most of the sleeping bags you use the rating "season", so the higher the number of seasons, the heat than it provides.
A-1-season bag should be used only in summer or indoors. Ideal for summer festivals, camping in the garden and short summersTravel. Also ideal to keep in the car just to be with friends. 3-season bags are good for use from Easter to autumn, but a little 'hot if it's a hot summer day. 4-season bags are designed for winter use, but still sticky, sweaty and summer weather conditions.
There are also 4 + season sleeping bags for use in extreme conditions, such as the Arctic or mountain climbing.
This is probably the best way to classify a sleeping bag, but some manufacturers use a temperatureAssessment to be done. This can vary greatly between manufacturers. Some manufacturers provide a sleeping bag with a score of +15 ° C, the other rate to -2 ° C. The EU has been confused with the introduction of a different classification system. This system uses four different temperature ranges:
Upper limit - the highest temperature at which a normal man would sweat a restful sleep without it.
Comfort - the lowest temperature at which a woman would be a standard relaxing bedtime, arelying on his back e.
Lower limit - the lowest temperature at which a normal man had a rolled up posture, a good night's rest.
Extreme - the temperature below which a standard might expect WOMAN strong feeling of coldness and maybe exposure or hypothermia.
It is absurd that a system can only further confuse the situation. Fortunately, most manufacturers to boycott. So, the season Rating stick. Heat is a subjective thing. So if you feelthe cold more than most people go for an extra season, which would buy another (eg, 4 instead of 3 year season) and if you do not feel the cold much less for a season. It is much easier than trying to decipher temperatures.
The weight and size of the sleeping bag is probably not important if you travel by car, simply choose a cheaper one. However, if you are backpacking, is lighter, smaller more comfortable and appropriate.
There are manyartificial fillings, which provide different levels of efficiency. I do not really think there is a great advantage over one another, just select the one that meets your needs for the season rating and weight / size.
The efficiency for the weight is usually considered real feather filling. But these sleeping bags are very difficult to clean because they do not like getting wet.
Most of the mummy sleeping bag with a zip from the left or right hand. You can usually zip linkBag to the right pocket to form a double bed. To verify if both options are zip to the bag you choose, if you will be able to want to do. But note that this method, the thermal efficiency can be created through the hole of the shoulder between the occupant is reduced.
