ThermaRest Trail Pro Self-Inflating Sleeping Pad

The Key Features

Diagonal Cut Foam 

The foam used in this camping mattress is not bulky and heavy yet still provides good thermal efficiency. This prevents the mattress from losing too much heat. The diagonal cut design assists in keeping the warmth in.

This feature makes this sleeping pad perfect for cold sleepers and camping in cold environments. With this mattress, you can have a warm and comfortable sleep.

Self-Inflating with Durable Valve

This sleeping pad has a self-inflating design. The valve is high quality and durable. Before you use it, allow it to inflate automatically by opening the valve for about 15 minutes.

The pad sucks in air and expands by itself because the core is made up of open-cell foam. This is an extremely easy way to inflate because you don’t need to manually huff and puff to blow it up. It does most of the work for you.

After that, you may check the firmness of the pad and either increase or decrease it as you like.

High Thermal Resistance (R Value)

The sleeping pad has an R-value (thermal resistance) of 4.8 which means that it has great resistance to the flow of heat. This feature makes it a 4 season sleeping pad. You can use it camping at any time of the year including camping during cold weather.

In cold environments, the mattress can give you warmth so you stay comfortable. This is an extremely helpful feature because unlike other sleeping pads with lower R values, this doesn’t limit your time of use.

Close the valve then unfold the mattress. Roll the mattress again starting at the foot end and as you get close to the head, open the valve again to let the remaining air out.

Keep rolling it and once rolled up, close the valve and keep your mattress inside the stuff sack and you’re done.
