Sleeping bags are essential equipment for outdoor camping and travel. A wide variety of sleeping bags are suitable for different purposes. Each has its own characteristics. What should outdoor enthusiasts choose? According to different purposes, the sleeping bags are generally divided into two categories. One type of sleeping bags is relatively thin and is used for general travel or camping. Most of these sleeping bags are used in the three seasons of spring, summer and autumn. There is also a category of sleeping bags for colder environments and even some adventure activities. Such sleeping bags are generally called professional sleeping bags. Ordinary sleeping bags are relatively cheap and widely used. Professional sleeping bags are very elegant in design and materials, and their prices are relatively high. However, if you go camping in winter or go to a high altitude area without a professional sleeping bag, you will not be able to. The difference in the use of sleeping bags determines the difference between the warmth of the sleeping bag and the manufacturing process.
The difference in grades and functions of sleeping bags is also mainly due to the use of different fabrics and thermal insulation layers. On the market, the relatively low-grade ordinary sleeping bag fabrics use normal nylon silk, and most of the insulation layers are artificial acrylic cotton. These sleeping bags are not very good in terms of heat preservation and are generally used only in an environment of about 20C and they are heavier in weight and compressibility. difference. High quality ordinary sleeping bags are much more stringent in material. Like the Ozark Ozark series of sleeping bags in the "sweet dream" and "climber" and other styles of sleeping bag fabric using a certain permeability of nylon, thermal layer using advanced microfiber cotton. The high quality materials make these sleeping bags excellent in warmth, weight and volume. Here, it should be added that any sleeping bag has a suitable operating temperature range, that is, different sleeping bags have their own "temperature scale". A typical temperature scale consists of three data, a minimum temperature: the lowest temperature limit used by the sleeping bag. Below this temperature is dangerous for the user. There is also an intermediate temperature; it refers to the ideal temperature for the sleeping bag to use the most comfortable. The maximum temperature refers to the upper limit of the temperature range, above which the user will be too hot to tolerate. In general, European and American sleeping bags are not suitable for Asians at the temperature scale, because Europeans are better at cold resistance than Asians, so we must pay special attention when choosing. There has been a case where the minimum temperature of the temperature scale is marked as -20C and the user is unbearable when the temperature is -5c in actual use. Of course, such as Ozark made a specially designed sleeping bag for the Chinese market. There is no problem with temperature standards. In recent years there have been many advanced man-made fiber materials that are widely used in sleeping bags insulation. Such special materials as INVISTA's seven-hole or four-hole cotton, 3M's Thisutale cotton and Hoechst-Celanese Group's Polargucrd cotton are mostly hollow fiber cotton and ordinary chemical fiber cotton in terms of quality and thermal insulation. Not the same level. More and more ordinary sleeping bags and professional sleeping bags have begun to use the above materials. Although many man-made fiber manufacturers announced that their materials are more than down in the comprehensive data of weight and heat insulation, but in fact far from this. Really professional sleeping bags, especially high-quality adventure sleeping bags are inseparable from down. In general, the amount of velvet in professional sleeping bags should be more than 80%, and the amount of velvet in ordinary feather sleeping bags should not be less than 70%, otherwise it will not meet the requirements in terms of compressibility, weight and warmth. Ozark Ozark professional series of two kinds of sleeping bags plush amount of 800g1000g, containing more than 85% of the cashmere, the minimum temperature standards are -10c and -15c, winter camping is more appropriate. The Ozark professional sleeping bag used by the Tibetan mountaineering team when it conquered the Nanga Parbat peak, known as the eaten demons, was plunged into 2000g, containing 85% grey goose down, sufficient to withstand the severe cold of -35C. The type of feather down and canopy looseness are also a factor, and goose down is better than duck down in general. The fabric of the sleeping bag is preferably capable of having a little waterproof function to prevent the sleeping bag from getting wet by the dew or the condensed water mist in the tent and affecting the warming effect. Of course, the ventilation performance is relatively more important, otherwise it would be very uncomfortable. Some brands of sleeping bag fabrics are made of special waterproof and breathable materials.
Sleeping bags are mainly mummy in design style. This design has a hood, large and small, and conform to the shape of the human, the side of the sleeping bag is equipped with a zipper to facilitate access, this design is a good insulation performance. In addition, there is an envelope-type sleeping bag, which not only uses comfort but also can pull the zipper apart for use as a quilt, and can be used both outdoors and at home. Professional sleeping bags are all mummy-type, and considering that people are most likely to feel cold when they are sleeping, they are particularly thick in the lower part of the sleeping bag. Some models also design a thicker foot pad. The head of the sleeping bag can be tightened to prevent cold air blowing. It is particularly worth mentioning that in the design of insulation layer structure of sleeping bags, in recent years, high-grade professional sleeping bags all adopt an upright lining design, and the fabric inside and outside the sleeping bag is directly sewn together. This design better prevents the movement of the down in the insulation layer space of the sleeping bag and makes the down distribution even. There are many kinds of sleeping bags, but when choosing a sleeping bag, like choosing other outdoor products, it is not the most expensive and most advanced, that is, what you should choose. Only the best one that suits you can match the outdoor sports you are engaged in. Ok.
