The common moisture-proof pads on the market

The common moisture-proof pads on the market are as follows:

　　A, single-layer moisture-proof pad:

　　 is sold in many outdoor stores, even Metro, Carrefour shopping malls also have a single layer of 5-7mm thick sponge pad. The material is very common, it is cut from the general dyed sponge pad, and the characteristic is that the price is very cheap, it is said that you can buy it under 10 yuan. The color is also very bright and beautiful, which is the first choice for attracting dish MM. There are also many disadvantages: too thin, not warm, easy to absorb (moist) water, and will squash and deform after long use. If you don't wear a jacket, it is easy to be broken by branches, and it is not wearable at all. Basically use 4 or 5 times to eliminate it. However, Sea to Summit and JACK WOLFSKIN have introduced a black foam single-layer moisture-proof pad. Although it is relatively thin, its wear resistance index and water resistance index are much higher than this low-grade color moisture-proof pad. (However, the index of attracting MM will drop) (The compressed sponge cushion I bought is 27 yuan. It belongs to this category. But it is thicker. It can be flexible. On the spring and autumn beach, you don’t need to lie on a sleeping belt and chat with beauties. Enjoy it. Usually put it on The cotton batting on the single bed instead of cushion.).

 

　　B, double-layer moisture-proof pad:

　　 is divided into three types: wear-resistant, tin foil, and egg nest. The tin foil type is actually to paste a layer of tin foil on one side of the single-layer moisture-proof pad by hot melt, which strengthens the water resistance (the use of tin foil faces down) and also enhances the tear resistance. The wear-resistant type is to paste the same area of ​​wear-resistant black rubber layer on one side of the single-layer moisture-proof pad. The wear-resistant layer faces downward when in use. Probably the thickness has increased to more than 7-9MM. Sleep comfort is good, even if you don’t wear a moisture-proof cushion coat, it can effectively resist twigs, sand and stone. However, the black rubber layer is naturally not as effective as the metal tin foil surface. If the contact surface is too wet, it will still absorb about 10% of the water. The egg nest type is a wavy concave-convex surface moisture-proof pad. People sleep on the foamed sponge of the wavy egg nest layer, which can form an air insulation layer between the human body and the concave and convex gaps of the egg nest, which has a good warmth retention effect. Moreover, the concave-convex type foams more fully than the flat type sponge, and it feels softer and more comfortable when sleeping on it. But the disadvantage is that after using for a long time, the concave and convex surface of the egg nest will be squashed and flattened slowly, which is to remind you that it is time to change the moisture-proof pad. The previous egg nest moisture-proof mats are all single-layer, one side is the egg nest wave, the other is flat. Nowadays, wear-resistant black rubber is basically attached to the plane layer. But I haven't found a metal foil surface. The above 3 kinds of moisture-proof pads are arranged according to the effect of use as water blocking effect: Tinfoil wear-resistant type = Egg nest wear-resistant egg nest comfort: Egg nest wear-resistant wear-resistant tin foil style Durability: resistant Abrasion-resistant thickness of tinfoil egg nest: Egg nest wear-resistant egg nest wear-resistant tinfoil type (abrasion-resistant and egg nest type moisture-proof pads are ugly, bulky, and heavier than tinfoil. Kill me Wouldn’t buy it either. But it’s more comfortable to sleep than tinfoil. On the beach, when someone exchanges such a moisture-proof pad for my tinfoil to play cards, I never hesitate. About thirty or fifty yuan.) (Tinfoil quality Lightweight and small, the price is 20 yuan. Of course, I am referring to double-sided, single-sided. This kind of moisture-proof mat is particularly cool when sleeping on it in summer. I use it as a summer mat at home. And this kind of cleanliness ．You can pad it there. It’s ideal on the grass and on the sand. It’s clean after a shake. Of course, it’s okay if you use it as a picnic cloth. Generally, when I have nothing to do in Zhuhai, I just bring a book with a pair of Face the tin foil moisture-proof mat, go to the depths of the park and lie down on the grass, leisurely and happy. But this moisture-proof mat is thin and it is uncomfortable on uneven gravel ground.)

　　C, professional EVA physical foaming moisture-proof pad:

　　 This kind of moisture-proof mats are generally produced by internationally renowned outdoor mountaineering brands. Use balanced physical foam, uniform thickness (9-15MM), and not easy to be crushed. Although it is also a sponge foam, the foam density is very high, and the water blocking effect can be higher than that of the tin foil surface. There are even several EVA moisture-proof pads with a tin foil surface. The price is also amazing, more expensive than self-inflating cushions. In the international outdoor product industry, this is the most high-end professional moisture-proof mat. (I usually use EVA washboard, from the beach on the beach to the snow-capped mountains on the plateau, from the gravel by the lake to the weeds in the jungle. This is the only one that performs well in all environments. The small gap between them can ensure the air permeability at the bottom of the sleeping bag. Hehe, camping in the clouds and fog of the mountains. In the morning, the inside and outside of the tent, the moisture-proof pads of double-sided tin foil are all wet with a layer of water. The washboard pad is okay.)

　　D, self-inflating moisture-proof pad:

　　 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 can be adjusted. Disadvantages: expensive; easy to puncture; bulky and heavier. (Undoubtedly, this is the most corrupt, and the quality and price are also very different. Air nozzles, most cheap air-cushion air nozzles are really not flattering, and it may not be possible to sleep a few times and people will sneer when they press it up. But in the air The thin plateau, the automatic expansion is greatly reduced, hehe, it is estimated that you don't have enough lung capacity to blow it in Tibet. Generally suitable for outskirts travel. Trekking and mountain climbing, its weight and reliability make me always choose to give up. )

　　E, the advantages of inflatable moisture-proof cushion inflatable cushion:

　　 Needless to say, it is more 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 use your mouth to blow.) (However, when you actually sleep, the weight-bearing area is too sunken and it is not very comfortable. If the foot is inflated, the muscles of the tight cushion are also very tense. But this cushion The biggest advantage is that you can go surfing and play in the water. Of course, you need superb skills. Later, after having a rubber boat, I completely put the 80 yuan inflatable cushion on the shelf.)

　　F, moisture-proof mat coat.

　　 Most of the moisture-proof pads currently sold are equipped with a wear-resistant jacket. The materials are fiber cloth and PU coating. Basically, it is for waterproof and wear-resistant, and the high-level ones are the CORDURA wear-resistant materials of DuPont and Duraflex fasteners. It is recommended that each moisture-proof pad be equipped with a jacket, which is not easy to get dirty. In terms of experience, since the moisture-proof pads are almost all externally hung on the backpack, be careful not to close the external strap too tightly, otherwise the elastic recovery of the sponge foam will be gradually reduced. Also pay attention to the tight rope straps of the moisture-proof cushion jacket, and retract it into the jacket after tightening. Don't leave it outside casually, otherwise it will be easy to hang branches when crossing the jungle. (If you don’t have a jacket, you can buy a little tarp and make it yourself. You can buy it in the building materials market. Ten yuan per meter long, four meters wide and four square meters.)

　　G, the configuration I am used to, I usually roll a double-layer tin foil moisture-proof pad inside the EVA washboard pad. As mentioned earlier, EVA is used to sleep in a tent. The tin foil pad is used to sleep outside the tent, have a big meal, and play cards. Anyway, play by yourself. You can put your clothes in the tent at night. In more severe environments, such as snow-capped mountains, heavy rain lakeside, adding a tin foil pad under the EVA mat is more secure. Because the mats are heavy, they have to be bought separately, so I generally omit them. But camping on the ground covered with gravel, no mats, stepping on the bottom of the tent without the protection of moisture-proof pads, hehe, it hurts. Therefore, I always bring two moisture-proof pads — an EVA washboard pad and a double-layer tin foil moisture-proof pad. Of course, these two moisture-proof cushions add up to be very light, the weight is generally one-third of the self-inflating cushion, it is very convenient to hang it on the backpack.

H: Inflatable bed In addition to being used as a bed at home, the inflatable bed can be used as a floating bed when you go to the wild or seaside camping, or go swimming or rafting on the water; put it in the office, take a lunch break or rest after work or exercise, or take a nap and many more. If you have a car, you don’t have to go to an outdoor store to buy a noble self-inflating moisture-proof cushion. A two-person luxury air bed comparable to Simmus and an electric air pump costs only 500-800 yuan. It weighs more than five catties, and it is uncomfortable for people to carry, but it is okay to have a car to carry.
