Aluminum foil is used to reflect heat in the sun, so when using it, the aluminum foil side is basically facing up. In response to this, the egg nest also has an aluminum foil surface, but you can choose to have the aluminum foil surface on top or bottom when using it (the aluminum foil surface makes people feel colder when the temperature is low and conducts heat quickly). Ranking according to the importance of various aspects: In terms of night heat insulation effect, aluminum foil is not as good as egg nests and inflatable moisture-proof pads. In terms of price, the difference in quality between expensive and cheap inflatable moisture-proof pads is obvious.
The popular Therm-A-Rest is not cheap. There is no obvious difference between expensive and cheap inflatable moisture-proof pads, such as egg nests and aluminum foil moisture-proof pads. They can be purchased for less than 100 yuan. enough. In terms of weight, inflatable mattresses (often accompanied by an air pump and not heavy) are the lightest, but the difference between egg nests and aluminum foil moisture-proof mattresses is not that big. In terms of storage, the inflatable moisture-proof pad is the smallest, but squeezing it in is a bit troublesome. Squeezing a sleeping bag is enough effort, so I prefer the egg nest, which is very convenient to plug in. Regarding the sound of the moisture-proof mat when I turn over at night, I can't stand the sound of the inflatable moisture-proof mat. The sound of aluminum foil is relatively quiet, and the egg nest is basically silent. In terms of maintenance of moisture-proof mats, air mattresses occasionally need to be repaired if they are torn.
Aluminum foil is often punctured by grass, but it doesn't matter if you are not afraid. The thickness of the egg nest will make it difficult to touch people if it is punctured, and because it is made of foam, it is difficult to puncture it. Once the things are removed, the gap will not be obvious.
