What does the R-value on the Sleeping Pad Mean?


R-value is a measure of thermal resistance. It shows how well a product protects against heat circulation.

For sleeping pads, the R-value measures how well they shield you from the cool ground. The greater the R-value, the far better the insulation of the material. Sleeping pads normally have an R-value between 1 and 8.

One of the most common arrays is 2-5. sleeping pads with an R-value listed below two generally do not insulate you well from the chilly ground and should be avoided. Pads with an R-value over four will provide good insulation but might be bulky or hefty for backpacking.


How to Measure the R-value of the Sleeping Pad?

The commonly accepted way of testing R-value is the ASTM R-value test method, which most brands use. It is done by placing the cold and hot plates on each side of the sleeping pad, then using an electronic sensor to determine how much energy is needed to keep the hot plate at a constant body temperature. Finally, the R-value size of the pad can be determined. The larger the R-value number read means better insulation.


How Important is the R-value of the Sleeping Pad?

To get a good night's sleep, you must choose the right resting pad R-value that matches the coldest temperature you can expect. In our camping program, the R-value is very important because depending on the climate when you plan to sleep camping will determine what R-value sleeping pad you should bring.

The dangers of using the wrong sleeping pad

When it comes to survival, the warmth provided by a sleeping pad is its most important feature. Winter camping is the worst, and it will be a disaster if you are not prepared for it. With the wrong R-value sleeping pad, you could face some dangers; in the best case, you could simply wake up aching and cold all over and be invaded by the flu virus; in the worst case, you could lose your temperature and compromise your life safety. In short, the sleeping pad's R-value is a matter of survival, and choosing the right R-value is an essential part of camping activity planning.
