How to select and use Sleeping pad?

Sleeping pad selection and use
There is an air cushion on the left and a foam cushion on the right. There is a self-inflating cushion in the middle. How do you choose for reloading?
Sometimes the idea of ​​lightweighting tends to pay more attention to weight rather than volume. After tailoring, foam pads that can be used for multiple purposes are more favored by lightweight players.
Foam cushions can be used as backpack backboards, seat cushions, and sleeping cushions, and are popular among lightweight players.
Keep warm first: winter camping, high-altitude camps
Camping on foot in winter, or camping in high-altitude cold areas, the night temperature is below 10 ℃, the earth is cold, if you want to sleep well, the sleeping mat must be warm. You can choose an inflatable cushion with an R value higher than 5, or you can choose an inflatable cushion + foam cushion combination with an R value of 3-5, and the R value can be perfectly superimposed.
The combination of foam cushion + inflatable cushion can take into account warmth and durability.
It is worth mentioning that the R value of the snow surface is only 20/1 of that of the ice surface and the rock surface. For camping in an ice and snow environment, try to choose a clean and flat snow surface to place the tent sleeping pad.
Durable: Extreme climbing environment
In the extreme climbing environment, foam cushions are the mainstream. You can see that all the climbers’ backpack photos are bundled with a yellow egg trough or a large silver roll. There is no need to worry about air leakage, no need to blow air, just throw it on the ground. The foam pad is the most compatible with these extreme environments.
Summarize
Sleeping pads are responsible for separating people from the cold ground, and they keep warm by locking the air. Take a look at the three sleeping mats, each with its own advantages:
The foam pad is the most durable, but it has a large packaging volume and a relatively low R value.
When the air cushion is stored, it is small and light, and the R value can be made high, so it is afraid of air leakage.
Self-inflating cushions are very comfortable to fall asleep, and the R value is also good, but the warm-to-weight ratio is very low, consider it as appropriate.
The outdoor environment is complex, we fully understand the sleeping pad, and with continuous practical experience, we can find the most suitable outdoor sleeping plan
