Outdoor tent camping trip and coping with temperature loss!

（1） Tent

The outdoor life starts with tents. Tents can be good or bad, with thousands of yuan expensive and dozens of yuan cheap. The difference lies in the design and materials of tents. A good tent has three characteristics: waterproof, warm and breathable. The material shall conform to the above three characteristics, and shall be of toughness, which can withstand stretching without cracking.

Each region has a different climate. For example, Tibet belongs to a plateau area with few vegetation. The climate is characterized by a large temperature difference between day and night, strong wind and dry, but little rain. Therefore, the choice of tents must focus on good heat preservation and strong toughness. The inland is rainy and humid, so the heat preservation and waterproof type should be selected.

The tent brand we use is Sanfeng Piaoxue, and the price is about 1000 yuan. This tent is characterized by its ingenious design, which is both ventilated and warm, the metal frame is tough and firm, the outer tent is tough, and the wind rope hook is also arranged reasonably, which is suitable for use at low temperatures. But this tent also has some regrets. In humid areas, the inside of the outer tent will be drenched every morning. This is because the air is humid and the water vapor freezes at low temperature at night. If it is sunny, you should take it out to dry every day. If it is cloudy and rainy, you can only take a bucket of paper to wipe it up, otherwise you can't sleep that night.

（2） Sleeping bag

Next is the sleeping bag. As far as I know, the goose down sleeping bag is the most insulated sleeping bag at present. Goose down is not only thermal insulation, but also very moisture resistant, and it also has the effect of moisture removal. We use a black ice goose down g700 mummy sleeping bag. The price is more than 800 yuan. It can keep the cold from minus 10 degrees. It is about the size of a large bottle of cola when it is put away. When it is opened, it will automatically inflate and expand greatly. It is very comfortable since it is covered. Because the goose has the function of automatic moisture removal, you will find that the outside of the sleeping bag is wet every morning. Don't be afraid, it is the moisture captured by goose down and can be dried with a bucket of paper, It can also be dried in the sun.

（3） Brushed inner sleeping bag

Fleece sleeping bag is very cheap, about tens of yuan, but it is very important. It can be used as a bed sheet or as a sleeping bag liner. When we sleep at night, we will emit a lot of moisture. The fleece liner can effectively absorb human moisture. It is easy to take it out in the daytime to dry or blow dry, because the fleece sleeping bag is easy to dry. If the atmosphere is cold at night, it can be used as the liner of the sleeping bag to improve the insulation effect of the sleeping bag.

（4） Automatic Inflatable Cushion

Inflatable mats are also very important outdoors, especially in the humid winter. The ground is wet and cold. Inflatable mats can effectively prevent the ground moisture and cold low temperature from eroding our body temperature. At the same time, they are also very soft to sleep with, and the price is within 200 yuan (single person).

（5） Damp proof pad

**Two sets of moistureproof mats are available. One is large and thin, which is placed underground outside the tent to prevent water vapor from corroding the bottom of the tent. The other is thick, which is placed at the bottom of the tent, to effectively prevent moisture from affecting the bottom of the sleeping bag. With the above five magic weapons, we can spend the winter outdoors in the west and southeast. * * also carries an electric blow bucket for drying clothes, sleeping bags and tents. Because the mainland is too wet, clothes are easy to get damp.

（6） Power Bank

The power supply for outdoor life is also the key. Without power supply, you will not only lose all contact with the outside world, but also lose the lighting. Therefore, the power bank is also very important. We use a large 20000 mA power pack, which has three pieces. Although it is very heavy, it can maintain the mobile phone and lighting for about a week. Although this kind of charging treasure has a large capacity, it takes more than eight hours to charge. This is the law of conservation of energy.

（7） Folding solar charging panel

This kind of solar charging panel is very effective on the plateau. Because the sunlight in the plateau is very abundant and fierce, the charging efficiency is very high. The 20000 mA charging bank mentioned above can be fully charged in about seven or eight hours. It can be seen that the charging effect of the solar charging panel on the plateau is no less than that of ordinary AC power. But it has little use in the mainland because there is too little sunshine.

（8） Cycling clothes

Even if the weather is colder, we will sweat during cycling, and we will feel cold only when we stop. If it is summer, we only need to wear a thin cycling suit. Even if we sweat a lot, we are not afraid of it. The cycling suit is made of fast drying cloth, so the sweat will soon dry.

Riding in winter is totally different from riding in summer. Try to avoid sweating, and it's easy to catch cold. If you have the conditions, try to buy special clothes for riding, even if you sweat, it is easy to volatilize. When we went out of Shenzhen, each of us had two sets of cycling clothes, but we had been outside for a long time and did not know where we had lost them. The only thing we have left is a suit of jacket for each person. The jacket is very warm and rainproof, but it can't stop the body from sweating, and the moisture can't evaporate. It's wet inside and easy to catch a cold.

（9） Thermal underwear

When the temperature is below zero, the wind is strong, and it is very cold to ride, especially when going downhill. A piece of thermal underwear can bring you warmth. Others need a lot of additional equipment. People who have been wandering outside for a long time must not make do with their personal belongings. They must plan carefully to avoid embarrassment in the outdoors.

（10） Correctly select the tent setting site

Tents can not be set up anywhere. We should not be far away from human gathering places. * * choose to be in police stations, township governments, banks and other monitored places. In remote areas, we should also choose to be in village committees or discuss with local people in their yards. Especially when traveling in Tibetan areas on the plateau, you should never go far from the highway to set up tents in the depths of the grassland, because there are other wild animals in those places besides yourself. The temperature difference between day and night on the plateau is large. If you don't make adequate preparations, it is easy to lose temperature. If you still feel very hot when the temperature outside is very low at night, it indicates that your life is in danger because of the temperature loss. It is not recommended to travel alone on the plateau, but * * travel together.
