Season camping, how to choose moisture pad

Written byAdventor

Outdoors who really understand and really love camping will not give up camping because of "cold". They camp on empty, snow-covered wilderness and are warm and harmonious. Where did this warmth come from? From the choice of campsites, the construction of tents, the temperature scale of sleeping bags, the matching of clothes, the production of food, and the use of accessories, we can explore in depth. Let's talk about how to choose a moisture barrier when it comes to winter camping.
First, the role of the moisture pad
After sunset, the ground heat dissipated quickly and became cold in a short time. When lying down during camping, the body directly touches the ground. At this time, the conduction will bring the body heat to the ground, causing the body to lose heat and produce a feeling of coldness. Moreover, the ground is uneven and the moisture is heavy, and it is uncomfortable to lie directly on it. These problems are solved by the moisture-proof pad.
It can be seen that there are three main functions of the moisture barrier:
1, keep warm
2, moisture
3, flood control
Then, how to play the above three functions of the moisture-proof pad, you have to start from its principle~
Second, the principle of the moisture pad
The principle of moisture-proof pad: Block the heat exchange between the human body and the outside world, form a layer of thermal insulation around the human body, and block the loss of heat from the human body to the maximum extent, thus exerting the heat preservation effect.
In terms of thermal conductivity, metals are the most conductive to conduct heat, while feathers, foams, and gases have low thermal conductivity. Therefore, moisture-proof pads are often considered from the perspective of foam and aeration.
Third, the type of mat
Foam moisture-proof pad: It is made of XPE and EVA. It has good strength, toughness and tensile strength. It is crusted (embossed) by high-temperature rigidity in the process to enhance water resistance. At the same time, it enhances the appearance, water repellency, and also improves the toughness, and because of the grooves of the pattern, the feeling of breathability is also better.
Automatic inflatable cushion: It is very comfortable to use. The inside of the moisture barrier is filled with a sponge with good compression and expansion. The gas in the sponge is squeezed, and the gas nozzle is closed to make the inside of the gasket semi-vacuum, and the volume will become smaller; open the nozzle, Under the action of external air pressure, the sponge expands and can automatically suck the air into the pad. Therefore, it is called an automatic inflatable cushion, and the air-filled moisture-proof pad has very good elasticity.
Manual inflatable cushion: also known as air bed, was first used in the country as a floating pad on the water, and later used by some people as a mat for camping. The feature is that the moisture resistance is good, but the volume is large and heavy, the inflation and deflation are troublesome, and the inflation and exhaust are troublesome.
From the price comparison: manual inflatable cushion> automatic inflatable cushion> foam mat
Contrast from volume: manual inflatable cushion > automatic inflatable cushion > foam mat
Contrast from warmth: manual inflatable cushion> automatic inflatable cushion> foam mat
Fourth, winter camping, use of moisture-proof pad tips
In winter camping, in order to double the warmth, the method of superimposing the moisture-proof pad can be used;
1. Lay a thick layer of plastic cloth on the ground (similar to the material and thickness of the greenhouse), the area should be larger than the tent area to better moisture;
2. Build a tent on a plastic sheet;
3. Lay foam mats are placed inside the tent;
4. Place an automatic inflatable cushion on the foam moisture barrier.
If you are camping yourself, you can also use a gas bed if conditions permit.
