   The common view now is that in outdoor camping, warmth mainly relies on sleeping bags, which is not completely explained. In fact, in outdoor camping, warmth is a systematic project, and the main combination is a combination of tents, sleeping bags, and moisture-proof pads. It can be said that none of them is indispensable. Without any one, you will feel cold.

   This time we will talk about sleeping bags. When purchasing sleeping bags, we should not blindly feel the thickness of the sleeping bag directly because it is not reliable. We need to pay attention to two parameters most, one is the extreme temperature scale of the sleeping bag, and the other is the filling material of the sleeping bag.

   I have introduced a lot about the temperature scale of sleeping bags before. Currently, most sleeping bags have two identification methods. One is to directly mark a fixed limit temperature for you, such as -20 degrees, and the other is to mark a range from red to blue, gradually changing. Anyway, we need to look at the lowest limit usage temperature. Generally, sleeping bags with lower limit temperatures have better insulation performance and correspondingly higher prices, The specific sleeping bag you need to purchase with the extreme temperature scale depends mainly on the midnight temperature of the camping location.

   Comfortable temperature: The most comfortable sleep temperature for normal adult women.

   Temperature restriction: the best sleep for normal adult males

   Extreme temperature: Generally refers to the temperature before normal adult women experience health problems or danger during sleep.

   The concepts given above are only for reference, because each country, population, ethnic group, and others have different cold resistance abilities. Even in our country, southerners are more resistant to cold than northerners. In fact, I suggest that you don't buy too thick sleeping bags when purchasing them, because too thick sleeping bags can only be used in winter and cannot be used in spring. My suggestion is to directly buy two sleeping bags, one thicker and one thinner. In particularly cold environments, you can use two sleeping bags together. In summer, you can use a thinner one, and when it's slightly cold, you can use that thicker one. There are various combinations depending on the temperature.

   Next, let's talk about fillers. Currently, most sleeping bags are filled with down, hollow cotton, fleece, etc.

   Duvet sleeping bags are relatively lightweight and have good warmth retention. Generally, high-quality sleeping bags are filled with down. For professional climbers, hikers, and other groups, the first choice is also a down sleeping bag. Down sleeping bags also have drawbacks. Once wet, down sleeping bags lose their thermal insulation properties and are not easy to dry, so it is important to be waterproof.

   Hollow cotton is composed of various tubular fibers, and its insulation mainly relies on the air in the fiber holes. Although its insulation and compressibility are not as good as those of down sleeping bags, and it is also relatively heavy, hollow cotton also has advantages. For example, hollow cotton sleeping bags still have very good insulation ability even after being damp.

   Fleece sleeping bags are generally made of polyester fiber, which is a bit like a blanket and has a certain degree of warmth retention. If used, they are basically used as the inner liner of the sleeping bag.

The style of the sleeping bag

   There are various styles of sleeping bags nowadays, including mummy and envelope styles. Mummy sleeping bags are commonly used in professional mountaineering, hiking, high-altitude cold and other places. Mummy sleeping bags have narrower steps, and then wider and wider upwards. The shoulders are the widest, and the hat on the head can be tightened, providing excellent warmth retention.

   Half rectangular, the structure of this sleeping bag is rectangular, and the space inside is slightly larger than that of a mummy sleeping bag, but its warmth retention is slightly inferior to that of a mummy sleeping bag. My first sleeping bag used this one.

Envelope style sleeping bags, as mentioned here, do not have a hat and have a zipper that can be opened. They are a bit like quilts, with average warmth retention and relatively heavy weight. They are only suitable for weekend picnics and camping, and are not recommended for professional outdoor activities.
