To sleep well is the most important thing while we are camping at the outdoors, so that we can recharge and recover for a brand new day.
Necessary for a good nights’ sleep in the backcountry, sleeping mats are the barrier between you and the cold, hard ground, preventing the ground from sucking the heat out of you and also makes it more comfortable to sleep.
Some mats use R-values to indicate their insulation. The "R" stands for resistance to heat transfer. R-value is a sleeping mat’s ability to insulate its user from the ground. The higher the R-value, the warmer it will be.
In springtime, Hong Kong is usually warm and humid, which means that almost all types of sleeping mats meet the insulation requirement. In winter or overseas camping where temperature ranges from 0℃to 10℃, sleeping mat with 1.2+ R-value sounds like a better choice.
The three main categories of sleeping mats include foam, air or self-inflating. By comparing their thermal retention ability (R-value), thickness (the thicker the comfier) and compatibility, you can make an informed choice of which types of mats is best for you.
