Sleeping mats provide a comfortable insulation layer between you and the ground. They serve two purposes to ensure a good night’s sleep: preventing your body from losing heat directly to the ground, and providing comfort. The first self-inflating mat was created in 1971, and this is perhaps the origin of the very broad style that has led to current designs. Contemporary designs are increasingly popular due to their comfort, light weight and small packed volume.
A sleeping mat is important. A sleeping mat and sleeping bag are the main things that keep you comfortable and warm at night inside your tent. Because the ground is colder than your body and is very conductive, when you lie on the ground, heat quickly goes from your body to the ground.
