One third of a person's life is spent in bed, as the saying goes, half the day and half the night. This is the slogan of Simmons, and it is also the case in life. We are very concerned about the quality of sleep, especially whether the bed is comfortable or not. We spend a lot of money to buy high-end mattresses. Thousands of dollars are just high-end entry-level models. Why do people spend so much money on mattresses in buyers and ignore your "Simmons" outdoors? Many of these people around me carry birds and elephants, and the MSR tents use expensive sleeping bags, and the moisture-proof pads are bought by Taobao for dozens of dollars. I asked them why you spent so much money to buy equipment for yourself, but could not bear to buy a better moisture-proof pad? They replied to me and said, "I don't think the damp pad is important. It can be used on the ground"
Self inflating mats is a necessary equipment, as important as sleeping bags. Because the moisture-proof pad can not only reduce the discomfort caused by sleeping on uneven ground, but more importantly, it can isolate the cold feeling on the surface of the earth! Even in summer, the temperature of the earth’s surface is still lower than the temperature of air. When we touch the earth’s surface, the conduction will bring the heat of our skin to the ground, causing the skin to lose energy and produce a cold feeling, so we Moisture-proof mats are needed to help us do the isolation work, and will not lose temperature due to energy loss! The isolation principle of the moisture-proof pad is the same as that when we use sleeping bags and warm clothes. They use a layer of almost non-flowing air as an insulation layer to block the low temperature of the outside world. The effect of isolation varies depending on how much air layer and fluidity the air layer can use.
Let's talk about it a little more! You will catch cold on the ground. In the long run, rheumatoid arthritis will find you. Outdoors, especially in winter, a moisture-proof pad that does not function effectively will make you sleep on the ground!
Just like the working principle of the stuffing in sleeping bags and clothing, the moisture-proof pad also blocks the heat exchange between your body and the outside (ground) cold air. She isolates a layer of dead air (DeadAir) between your body and the ground, and uses the heat of your body to gradually increase the temperature of this layer of "dead air", making it a heat exchange between your body and the ground A barrier to play a thermal insulation and moisture-proof effect. The high efficiency of the moisture-proof pad and the amount of "dead air" that she can otherwise save and the ability to prevent air convection.
