What Is R-Value in Sleeping Pads?

R-Value refers to the measurement of the sleeping mat’s resistance to heat loss when you sleep at night. A pad loses heat to the ground, but if it has a high R-Value, it resists thermal conductivity and provides insulation to protect you from the cold ground.

Why Choose the Highest R-Value Sleeping Pad

A sleeping pad with the highest R-Value is the best for camping in places with freezing temperatures because it insulates your body well. Sleeping pads with low R-Values starting from 1.0 are suitable for warm weather, and those with an R-value of more than 5.0 are perfect for cold weather. A self inflating pad with the highest R-value offers the best insulation. If you want to increase R-value and warmth, you can combine two sleeping mats.

The chart below shows the correlation between R-values and Temperature Ratings.


Factors to Consider When Choosing a Pad

Opting for a sleeping pad with a higher R-value offers many benefits. You will likely not overheat when you get this type of sleeping pad, unlike a sleeping bag that is too warm. Aside from R-value, find other aspects to consider when picking a sleeping pad.

Maximum Comfort

Nothing is more important than enjoying a good night’s sleep after spending your day performing different activities. A camping sleeping pad with 2-3.5 inches of thickness that incorporates foam and air provides the highest comfort and insulation.


Every outdoor activity might require a different type of pad. Are you planning to go backpacking? A lightweight air pad is the best backpacking sleeping pad. But if you car camp or camp near your car, you may go for foam pads or self-inflating mats that promise more comfort and insulation, although they may be on the heavier side.

Intended Use

For winter camping, an insulated sleeping pad with an R-value of 5 and above will keep you warm and ensure sufficient padding from the frozen ground. When camping in summer, an air mattress with an R-value rating of 5 or less gives enough thermal resistance from the cold ground.

Type of Sleeper

If you’re a side sleeper, pick a foam pad that doesn’t compress or deform when your weight is on one side. A self-inflating sleeping pad with foam and air core will ensure you don’t feel the hard ground beneath you.

Additionally, women may need a warmer sleep system because they tend to be cold sleepers and have less capacity to produce heat when temperatures drop during the night. A sleeping pad with a high R-value will guarantee a warm night’s sleep.

Easy to use

Whether you are backpacking or camping, your sleeping pad should be effortless to set up when you need to rest or roll up when leaving camp..

What can I do if my sleeping pad is losing air?

If your sleeping pad is losing air, it can be caused by a puncture. Most sleeping pads come with a repair kit. Follow the instructions when applying a patch on the leaking part. You can also ask for a replacement from the seller if a warranty covers your purchase.

What makes a sleeping pad insulated?

A sleeping pad may have foam, air, or both – these compositions warm with your body heat, insulating you against the cold. A self inflating sleeping pad may also include heat-reflecting technology causing it to direct heat back.

How do you prepare your self-inflating pad for storage?

The first step is to clean your pad with a wet cloth and mild soap. Open the valve and do not allow water to get inside. When breaking camp, properly roll the pad and store it with the other gear.
