Entering the autumn, it is the best season to engage in outdoor hiking, cycling and mountaineering. If you are a “new donkey” entering the outdoor donkey circle for the first time, you will put a sleeping bag in your backpack to solve the sleep problem when you are excitedly preparing to participate in outdoor tourism activities with the old donkeys.
According to the material, the sleeping bags are divided into cotton sleeping bags and down sleeping bags. The advantages of cotton sleeping bags are the price, and they still have a certain thermal insulation effect in the case of slight damp; The advantages of down sleeping bags are light weight, small packaging size, and good thermal insulation; The warmth retention of down sleeping bags is one of the strongest among existing types. Therefore, travelers who travel far to mountains and rivers or travel in spring and winter always think of it. However, since the lining of the down sleeping bag is filled with duck down, it is naturally not easy to store, and certain skills are required for folding.
The human body is the source of heat for the sleeping bag. If you do a warm-up exercise or drink a hot drink before going to bed, your body temperature will increase slightly and help shorten the warming time of the sleeping bag.
The water absorbed by the sleeping bag is not mainly from the outside world, but the human body. Even in extremely cold conditions, the human body will still discharge at least a cup of water during sleep. The thermal insulation cotton will bond and lose its elasticity after being wet, and the thermal insulation ability will decrease. If the sleeping bag is used continuously for several days, it is best to dry it in the sun. Frequent cleaning of the sleeping bag will keep the insulation elastic.
