Moisture-proof mat has two important functions: it makes you sleep more comfortable, especially on harder and less flat ground; it is a layer of insulator between your body and the ground (of course it is not anti-electric, but only isolates the body from Heat transfer between the ground).
how it work
Like the working principle of the stuffing in sleeping bags and clothing, moisture-proof pads also block the heat exchange between your body and the cold air outside (the ground). She isolates a layer of dead air 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 the heat between your body and the ground A barrier of exchange, thus exerting the effect of heat preservation and moisture proof. The effectiveness of the moisture-proof pad depends on the amount of "dead air" it can hold and its ability to prevent air convection.
How much storage space do you have:
If your backpack is always full of equipment, then a lightweight moisture-proof pad is worth considering. But if you have a car or a boat, size will not be a problem
The type you can choose
There are many types of moisture-proof pads on the market. It is not time-consuming to understand their characteristics before purchasing.
Advantages: Needless to say, they are definitely comfortable, and the softness is adjustable, and the price is not expensive. Disadvantages: too heavy, too big, and easy to break. Air cushions also cannot provide good insulation. In addition, she also has great demands on your lung capacity! (You need to blow with your mouth.)
Open-cell Foam Pads:
Made of a foam material like the sea surface. Advantages: more comfortable, lighter, cheaper and warmer than inflatable. Disadvantages: Because the material is an open structure, it has poor moisture resistance and is not suitable for use in a humid environment. The heat preservation performance is worse than the closed air chamber type, and it is heavier, less compressible (not suitable for carrying), and has a shorter service life.
Self-inflating Pads:(visit: /product/self-inflating-mats/)
The open air chamber is enclosed in a waterproof nylon shell, which automatically expands when used. Advantages: It is as comfortable as the open air chamber, but the insulation is much better; it is waterproof and moisture-proof; the air volume of the air chamber can be adjusted.
There are many styles, shapes and lengths of moisture-proof pads. If possible, you can try different styles of moisture-proof pads before making a decision. There are some questions you can also consider:
How soft moisture-proof pad do you need? How long and wide do you need a moisture-proof pad? (There are single, double or multi-person moisture-proof cushions, and some are very narrow to save space.) Is it convenient to inflate, pack, and carry?
Finally, some subsidiary designs may influence your decision. For example, some moisture-proof cushions have multiple inflatable air chambers, making it easier to adjust the thickness of the moisture-proof cushion; while the moisture-proof cushion combined with inflatable pillows makes you more comfortable to use; the surface of the moisture-proof cushion with meshed concave-convex treatment can provide heat preservation and anti-slip function Can be improved; some are even more designed to conform to the shape of the human body, to save space. But for a mountaineer, a good night’s sleep may be a very important thing. If you are usually used to sleeping naked on a super-large wooden bed, it is best to choose a luxurious two-inch thick, full-length open room foam sleeping mat without worrying about the weight. If you are someone who can sleep on a harder bed, then a three-quarter-length closed room foam mattress is sufficient. You can use a half-length closed room foam sleeping pad when you are young. When you are old and your bones are a bit hard and brittle, you need to use a light, three-quarter-length expandable foam sleeping pad. In winter, bring a full-length closed-chamber foam sleeping pad and a complete repair tool to prevent the open-chamber foam sleeping pad from hooking.
