1. Try to buy down sleeping bags.

A sleeping bag filled with artificial materials is about the size of a down sleeping bag when opened, but it is much bigger to carry. In addition, sleeping bags filled with artificial materials are also heavy. Down sleeping bags are relatively expensive, but they have strong warmth and are smaller in weight and volume than artificial materials. Choosing down sleeping bags can't just refer to the temperature scale, because many sleeping bags are based on the physique of Europeans and Americans. When shopping, you must choose high-purity cashmere. 80%-90% pure velvet is better. American brand sleeping bag, more than 700 fillpower, very fluffy.

Nowadays, many sleeping bags can connect two sleeping bags with zippers to make double sleeping bags.

When buying sleeping bags, buy sleeping bags with different zippers with your partner. Generally speaking, men buy sleeping bags with zippers on the right and women buy sleeping bags with zippers on the left. The fabric of low-grade ordinary sleeping bags on the market is nylon, and the insulation layer is mostly artificial acrylic cotton. These sleeping bags have poor thermal insulation and can only be used in the environment of about 20c, and they are bulky and have poor compressibility. High-quality ordinary sleeping bags are much stricter in material. Any sleeping bag has a suitable temperature range, that is, different sleeping bags have their own "temperature scale". The general temperature scale consists of three data, one is the lowest temperature: it refers to the lowest limit temperature of sleeping bags, below which it is dangerous for users. There is also an intermediate temperature; Refers to the most comfortable ideal temperature for sleeping bags.

The maximum temperature refers to the upper limit of the temperature range. Above this temperature, users will be unbearably hot. Generally speaking, sleeping bags in Europe and America are not suitable for Asians on the temperature scale, because Europeans have higher cold resistance than Asians, so we should pay special attention when choosing them. There have been cases where the lowest temperature on the temperature scale is -20c, but users can't stand it when it is -5c in actual use. The type of down and the looseness of crown are also influencing factors. Generally speaking, goose down is better than duck down. The fabric of the sleeping bag should have a little waterproof function to prevent the sleeping bag from being wet by dew or water mist condensed in the tent, which will affect the warm-keeping effect. Of course, air permeability is relatively more important, otherwise it will be very uncomfortable. Some brands of sleeping bags are made of special waterproof and breathable materials.

How to choose a dirty sleeping bag?

Choose a sleeping bag according to your body shape: a sleeping bag that is too small will be too tight to turn around and uncomfortable; Sleeping bags that are too big are empty, which will affect warmth.

Pay attention to the temperature scale of sleeping bags:

All along, the most important data for choosing sleeping bags is the temperature scale. The temperature scale is divided into three data: the limit temperature scale (the lowest temperature scale, blue temperature scale), the comfort temperature scale (some manufacturers also divide this temperature scale into high and low temperature scales, blue to orange temperature scale) and the highest temperature scale (red temperature scale). It should be noted that the temperature scale is only a relative concept. There are no industry associations and standards for sleeping bag products, neither at home nor abroad. Some big brands and research institutions calibrate their products according to laboratory tests and field experience. This temperature is for reference only. It will vary from person to person and from environment to environment. Generally speaking, the temperature scale given by the manufacturer is measured by people with good physique in an ideal environment. Pay attention to this when choosing to buy, and be conservative. Sleeping bags generally have three temperature scales:

Only one temperature is marked. Usually this temperature scale is the limit temperature scale of this sleeping bag. If used below this temperature, it may be dangerous. The actual comfortable temperature of this sleeping bag varies from person to person. This sleeping bag has two temperatures, usually an extreme temperature scale and a maximum temperature scale (or an extreme temperature scale and a comfortable temperature scale). The highest temperature scale generally means that it will be too hot for normal use at this temperature. Mark three temperatures, namely limit temperature scale, comfort temperature scale and maximum temperature scale.
