Moisture-proof mats are very important when camping in the wild. They mainly have the following three functions:
First, flood prevention. Since it is difficult to find a flat place when camping in the wild, it is very uncomfortable to sleep and a dampproof mat is used, and the situation will be much better.
Second, keep warm, because the body is generally in direct contact with the ground when camping in the wild (only the thermal insulation effect of the bottom of the tent is minimal), so if there is a layer of moisture-proof pad between the body and the ground, the thermal effect will be many.
Third, moisture protection. When camping in the wild, the ground is usually very damp at night. Since the moisture-proof mat is waterproof, it can play a role in damp-proofing.
For mats, warmth, weight, comfort, durability, and size are all important in turn, but for a climber, having a good night's sleep is a very important thing. A good mat is also very good. important.
