The purpose and principle of moisture-proof pad

As long as anyone with outdoor camping experience knows, the moisture-proof pad is a necessary equipment, as important as a sleeping bag. 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.

Moisture-proof pads have two important functions: make your sleep more comfortable, especially on the harder, less flat ground; it is a layer of insulator between your body and the ground (of course it is not anti-electricity, just isolates the body from Heat transfer between the ground).

how to work

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.

Your plan: Just like buying other things, buying outdoor equipment can sometimes make you regret, because there are really too many things you need to consider, you will have many requirements for everything, and in most cases, you all Cannot be satisfied at the same time. The same is true for choosing a moisture-proof pad. You have many things to consider: insulation (the ability to isolate the body from heat exchange with the ground), comfort, weight, volume and durability. It is important for you to choose from the above conditions, and consider your Outdoor planning may be helpful to you.
