[High R value 8.8 / 8-layer 3D reflective structure] This R8.8 air mat is based on the R5.8 mat and has been strengthened to R8.8, further increasing its heat retention performance! This air mat is made of 20D nylon TPU and has a silver coating on the surface. This makes this mat perfect for outdoor use and long lasting. The interior of this mat is coated with an aluminum film that can withstand -30℃, further separating each independent air chamber to reduce heat loss and greatly improve heat retention. The aluminum film layer inside prevents radiation conduction due to human body heat and has a better heat storage layer. The film layer prevents heat leakage due to air convection heat dissipation. When you lie down, you can feel the warmth as if your body heat is reflected from the area you are touching. Our testers have used it in extreme weather with temperatures as low as -30°C, and there is no discomfort. Therefore, even if you use it outdoors in the harsh cold, you will not feel cold while sleeping. [12mm thick and comfortable to sleep on] This mat has been upgraded from 7cm to 12cm. The thickness makes it more comfortable to use. The thickness of the inflatable cushion can reach 12-13CM depending on the amount of inflation. For example, this mattress has increased bounce, so the surface of the mat can support your body in many ways and distribute pressure when you sleep on it. At the same time, this thickness also prevents moisture on the floor surface during use, allowing you to use it on the floor with greater peace of mind. Thanks to its thickness, this mattress is as comfortable as a bedroom mattress, and the soft, warm air mattress makes it easier to fall into a deep sleep, allowing you to get a good night's rest even outdoors, and feel better about the next day. [Ultra-lightweight, easy to set up, great use in a variety of situations] This inflatable mat has enhanced heat retention performance, and at the same time, its compactness and light weight means it won't be thrown away! The mat weighs only 410g and is small in size after storage, measuring only 10*18cm in diameter. After entering the storage bag, it can be held in one hand and is easy to carry! It is very compact and does not take up much space even when stored in luggage. In addition, as a result of pursuing lightness, there is no need to carry a heavy electric air pump, and air can be filled using an air bag. It is easy to set up and can be used even by beginners. The overall lightweight design reduces the pressure of your journey. It can be used not only for outdoor use, but also for various situations such as mountain climbing, camping, walking, etc., and is also perfect as a temporary mattress when you have guests at home.
