Before you buy, about the sizing. Our recommendation is to use the provided inflatable bag instead of other automatic inflators, as the inflatable bag will do a better job of reaching the maximum advertised size. The inflator will not reach the maximum size at 100% inflating power. Once you have used the inflatable bag a few times, you will be able to reach the maximum size more smoothly. 

We recommend choosing a model that is 20cm longer than your height. For example, if you are 180cm tall, you must choose L/200cm for the most comfort. (Because you also have to consider that the pillow takes up some space)

Light Tour latest technology LightCore™ structure, providing a 7.5 R-value. The ultimate outdoor hiking sleeping pad with the highest warmth ever. It is warmer and thicker than the previous R3.5 and 5.8 models, and is designed for European and North American body types. In the past customer feedback, we have counted a lot of user opinions and developed a more extreme outdoor sleeping pad again, which we call the strongest model. 

Compared to R5.8 and R3.5, the new R7.5 has better silver coating on both sides, and the thickness reaches 10cm, which can reach an R value of 7.5 in the authoritative test, which makes us very excited.  

Our models have always been famous for being quiet. The internal material of the sleeping pad will not produce obvious noise when the user turns over and is squeezed. In a two-person tent, you will not feel uncomfortable because of the noise made by your partner's body movement. We spent a lot of time testing different materials, and the final result made us feel relieved. 

Ultralight Durability: 20D ripstop nylon is one of the basic conditions to ensure that it has a high R-value sleeping pad. The moderate thickness ensures that the sleeping pad will not be too heavy. This is an ultimate outdoor hiking sleeping pad. The choice of fabric affects the final weight.
