Moisture-proof mats have two important functions: to make you sleep more comfortable, especially on harder, less flat surfaces; it is an insulator between your body and the ground (of course it's not electricity proof, it's just isolated from the body and Ground heat transfer).
how to work
Like the working principle of the stuffing material in the sleeping bag and the clothing, the moistureproof mat also blocks the heat exchange between your body and the outside (ground) cold air. She insulates a layer of dead air between your body and the ground, and uses your body's heat to gradually increase the temperature of this layer of "dead air," making it the heat between your body and the ground. Exchange a barrier to the effect of insulation and moisture. The effectiveness of the moisture-proof mat and otherwise depends on how much "dead air" she can save and the ability to stop air convection.
Your plan:
Just like buying other things, buying outdoor equipment sometimes makes you regret it because there are so many things you need to think about. You have a lot of requirements for everything. In most cases, all your requirements are not May be satisfied at the same time. The same is true for the selection of moisture-proof mats. There are many things you need to consider: Insulation (the ability to insulate the heat exchange between the body and the ground) Comfort Weight, volume Durability It is important for you to choose from the above conditions, and consider your Outdoor planning may be helpful to you.
How much storage space do you have:
If your backpack is always full of equipment, then a lightweight mat is worth considering. But if you have a car or a boat, the volume won't be a problem. Who does not want to sleep comfortable, sometimes I really can't wait to carry my Simmons.
Your choice of kind
There are many kinds of moisture-proof pads on the market, and it is not time-consuming to understand their characteristics before purchasing.
A. Foam plastic moisture-proof mats:
This kind of moisture-proof pad is the most common type. It uses high-pressure polyethylene material, and after foam molding, it is cut into pieces of a certain thickness according to different specifications, and it becomes our common moisture-proof pad. This kind of moisture-proof pad is characterized by closed-cell, non-absorbent, usually with a thickness of 45-fold foam cut into 0.8-1.0, the price is relatively low. Due to its low degree of durability, it is usually used once in foreign countries. China is a low-consumption country. People's consumption habits hope to be used multiple times to reduce input. To meet this requirement, some businesses have combined low-powered foamed sections with high-powered foamed sections. This is what we see in the market as a two-layer, dual-colored moisture-proof pad. Because the outer layer uses low-power foamed sections, the bottom The wear resistance is greatly enhanced. The advantage of this mat is its extremely low price and light weight (negligible); but the disadvantages are also obvious: poor durability, initial smell (mainly poisonous gas released from polymer materials), unfavorable to health, long time Even though the taste is gone, the toxic substances are still slowly released.
B. EVA mats:
From its name, we can know the material it chooses. EVA is also called back rubber. Compared with closed-cell foam mats, it has good elasticity and toughness characteristics, and therefore the price is quite different, and the first type of moisture-proof pad. It has nearly doubled the cost, but it has greatly improved comfort and durability. However, from the perspective of its appearance, it is difficult for the average consumer to distinguish between the two. The real EVA mats are rare in the domestic market.
C. XPE moisture pad:
XPE mat, also called semi-foamed mat, uses ultra-high pressure polyethylene material. Although this material is not as high as pure EVA material, its strength, toughness, and tensile strength are much better than those of closed-cell foams, but water repellency is not as good as that of closed-cell materials. Therefore, when the manufacturer makes such a moisture-proof pad, it passes through the process. The high temperature is rigid and crusted to enhance the waterproofness. Such a moisture-proof pad that is treated with a crust (embossed) not only enhances the aesthetics, water repellency, but also improves the toughness, and because of the grooves of the pattern, the feeling of breathability is also better. XPE is a new product launched in the last two years. Its price is slightly higher than that of closed-cell foams. The comfort of use has obvious advantages. It can be said that it is an ideal type of low-grade moisture-proof pad.
However, XPE is not as dense as foamed plastic in terms of appearance, but it feels a little rough, which often leads to misunderstandings, thinking that its comfort is slightly worse, but it is not. The biggest advantage of XPE is that it does not contain toxic chemicals and does not emit disgusting odors. This is the real reason why it has a higher price.
The above three kinds of moistureproof mats are generally economical and practical products. In order to improve the warming effect, some products will also be covered with a layer of aluminum foil, but please note that the cost of covering the aluminum foil is not high.
D. Inflatable mat: (airbed)
This type of moisture-proof mat, known as the air bed, was first used as a water floating pad in China and was later used by some people as a moisture-proof pad for camping. This type of air bed made of a cotton scraping fabric has a moisture-proof property. Good, but because of the larger size, heavier weight (may reach 7 kg or more), and the inflating and exhausting are more troublesome, it is an infrequent variety in outdoor damp proof mats.
E. Automatic inflatable cushion:
Inflatable mat is a noble family of moisture-proof mats. It is a high-grade product. The best mats are sold for more than 2,000 yuan. They are often the preferred products for outdoor trips. They are very comfortable to use, and their feelings are similar to the family's Simmons. In the production process, the inner part of the moisture-proof pad is filled with a sponge with good compression and expansion properties, the gas in the sponge is squeezed, and the gas nozzle is closed so that the pad becomes a semi-vacuum state and the volume becomes smaller. The gas nozzle is opened. Under the action of the outside air pressure, the sponge expands, and the air can be automatically sucked into the pad. Therefore, it is called an automatic inflatable pad. The moisture-filled pad filled with air has very good elasticity.
This kind of moisture-proof pad is divided into high, medium and low grades due to different materials. The low grade is generally made of PVC coated polyester and silk, so the quality will reach more than 1 kilogram. The middle and high grades often use PU-coated polyester and silk, and the inner core uses a high-quality sponge, so the compressive sensation and toughness are very good. In the bonding method, it can be divided into three ways of edge sealing, semi-adhesion and full bonding. The high-grade products are all processed by the full-bonding method. After the air filling, the mat looks seamless and comfortable. Because this kind of mat is filled with a sponge's inner core, the volume will be relatively large. In order to reduce the volume of the mat, some varieties will foam the inner part of the sponge into a honeycomb. When compressed, the volume will be greatly reduced, and the weight can also be controlled at 700. About grams, however, due to the more complex process, so the price will be more expensive.
There is also a technique to use the self-filling moisture-proof pad. To make it more comfortable, you can add 1-2 gas to the inflation port after the automatic inflation stops. This will make it more flexible, but also pay attention to it. Do not blow more, this is not a balloon, too much gas, may cause the adhesive layer to produce pores, which is not good.
Good self-contained moisture mats usually come with a repair kit, so you don't have to worry about accidents under any circumstances.
Trying no damage:
Moisture-proof mats come in a wide variety of styles, shapes, and lengths. If possible, you can try a different style of moisture barrier and then make a decision. There are some issues that you may also consider:
Do you need more soft moisture-proof mats? How long and how wide do you need a moisture pad? (The moisture-proof mats are single, double or multi-person, and some are very narrow in order to save space. Is it convenient to inflate, collect and carry them?
Finally, some ancillary designs may affect your decision. For example, how many moisture proof mats? Inflatable air chamber makes the thickness of the moistureproof pad easier to adjust; and the moistureproof pad combined with inflatable pillow makes you more comfortable; the moistureproof pad with surface textured treatment can improve the heat preservation and antislip function; some are more designed. A conical cushion mat that conforms to the body shape to save space. (Unfortunately, these designs are rare in the domestic market.)
The above are some suggestions on the selection of moisture-proof mats. For sleeping mats, warmth, weight, comfort, durability, and size are all important in turn. But for a climber, a good night's sleep may be a very important thing. Of course, there are too many conditions to consider, and it's really nerve-wracking. Maybe when you first purchase a moisture-proof pad, you'll still pick a cheaper one-person moisture-proof pad. It's not heartbreaking to throw that thing when you regret it.
