Sleeping bags are essential for camping and traveling outdoors. There are many kinds of sleeping bags suitable for different USES, and each has its own characteristics. How should outdoor sports lovers choose? There are two main types of sleeping bags according to their different USES. One type is thin and is used for traveling or camping. Most of these sleeping bags are used in spring, summer and fall. There is also a category of sleeping bags that are used for colder conditions and even for adventure activities. The average sleeping bag is relatively inexpensive and versatile. Professional sleeping bags are sophisticated in design and materials and are relatively expensive, but you can't go camping or traveling to high altitudes without them.
There is a suitable temperature range for any sleeping bag. The normal temperature scale consists of three data points, one minimum temperature: the minimum temperature limit used by the sleeping bag, below which it is dangerous for the user. And a comfortable temperature; The ideal temperature at which the sleeping bag is comfortable to use. The maximum temperature is the upper limit of the temperature range, above which the user will be unbearably hot. The temperature is just a reference, and it varies from person to person and from environment to environment. Generally speaking, European and American origin sleeping bags are not suitable for asians on the temperature scale, because europeans have higher tolerance to cold than asians, so we should pay special attention to the selection.
In recent years, many advanced man-made fiber materials have been widely used in the insulation of sleeping bags. More and more common and professional sleeping bags are using these materials. Although many man-made fibre manufacturers claim that their materials outperform down in terms of weight and insulation, this is far from the case. A true professional sleeping bag, especially a high quality adventure sleeping bag, requires down. In general, professional sleeping bags should have a velvet content of more than 80%, and ordinary down sleeping bags should not have a velvet content of less than 70%. Otherwise, compressibility, weight and warmth will not meet the requirements. The type and size of the down is also a factor, with goose down generally superior to duck down. The fabric of sleeping bag had better have a little waterproof function, in case the sleeping bag is wet by dew or condensed water mist inside the tent, affecting the effect of keeping warm. Of course, the breathable performance is relatively more important, otherwise it will be very uncomfortable.
Sleeping bags are mostly mummified in design. This design has a head cover, large top and small bottom, which is in line with the human-oriented shape. The side of the sleeping bag is equipped with zippers for easy access. This design has good insulation performance. In addition, there is an envelope-style sleeping bag, which is comfortable to use and can be unzipped as a quilt, both outdoors and at home. Professional sleeping bags are all mummified and are thickened at the bottom of the bag to allow for the cold in the feet. The head of the sleeping bag can be tightened to prevent cold air from blowing in. There are many different types of sleeping bags, but when choosing a sleeping bag, as with other outdoor products, it is not the most expensive or the most advanced or the best. Only the most suitable one can match your outdoor activities.
