The function of sleeping bag

Some people who love traveling and outdoor sports will bring sleeping bags with them when they go out on vacation, because sometimes they can't find a hotel at night and they will sleep on the floor. In order to ensure their safety and warmth, they will use sleeping bags. In fact, sleeping bags are a good material. In summer, they can also isolate mosquitoes and block the wind. So what are the functions of sleeping bags?

The role of outdoor sleeping bags

1. The role of outdoor sleeping bags

The function of a sleeping bag is only to keep heat loss as little as possible, while the human body inside the sleeping bag constantly generates heat to keep warm. The amount of heat generated by different individuals and situations is different. All sleeping bag temperature calibration systems are based on a standard human body, but such a standard human body basically does not exist.

A sleeping bag is a bag you use to sleep in. Currently, most sleeping bags on the market are marked with comfortable temperature and extreme temperature. The comfortable temperature is a series of temperatures that the user can sleep at throughout the night, with a maximum and minimum limit. The maximum comfortable temperature refers to the feeling of heat in the sleeping bag but not the kind of heat that causes a lot of sweating. It is generally defined as the sleeping bag zipper is open, the arms are placed outside, the head of the sleeping bag is not tightened, etc.

2. Washing of outdoor sleeping bags

Both synthetic cotton sleeping bags and fleece sleeping bags can be washed directly, or machine washed if your washing machine is large enough. When drying, try to lay it flat or hang it in multiple places to avoid excessive sagging. How to wash a down sleeping bag: According to down experts, a down sleeping bag only needs to be washed once every four years. The service life is about 10 to 12 years and can be cleaned 3 times. If it is not too dirty, it can be cleaned simply by using a towel dipped in gasoline to clean the surface material.

3. Packing and maintenance of sleeping bags

Before compressing and packing, turn the sleeping bag inside out and expose it to the sun. After making sure the inner layer is dry, restore it to its normal state, roll it up to squeeze out the air, then unfold it and stuff it into the packing bag from one end. To ensure even compression, turn the packing bag while stuffing it and apply pressure to the sleeping bag with your knees. In humid conditions, a plastic waterproof bag should be added to the packing bag.

As for the storage and preservation of down sleeping bags, compression is not a good idea because down sleeping bags need to breathe. The best way to store a down sleeping bag is to choose a large, breathable storage bag to keep it in a fluffy state. Down products should not be exposed to moisture and should be placed in a dry and ventilated place. After use, they should be exposed to the sun or air as much as possible to keep the sleeping bag dry and fluffy. If such conditions are lacking in the wild, this procedure must not be omitted after returning home.
