Naturehike High Air Ultra SGS Utility Model 4 Seasons Be Used At Thickness Inflatable Water Sleeping In Disaster Inflatable Bag Included R-Value R5.8

[Utility Model Registered] Naturehike high R value mat adopts the utility model registered NKTR (thermal energy reflection system) structure, and the radiation prevention function of the 8-layer aluminum film material makes it lightweight and prevents heat loss due to radiant heat transfer. Each independent air chamber is separated by a film to prevent heat loss due to convective heat transfer by air circulation, and the interior design with a multi-dimensional heat reflection structure keeps out the cold. [Compact and ultra-lightweight] Naturehike high R-value mats are made of ultra-lightweight materials, with a total weight of only about 500g. M size: 183x64cm L size: 196x64cm Mummy type: 470g, 500g, Rectangular type: 560g, 620g, 650g. The mummy series can be connected with a string to combine into a double air mat. [SGS certified high R-value] R-value is a numerical value (thermal resistance value) that indicates insulation. The higher the R-value, the less cold air is transmitted and the higher the insulation performance. Naturehike high R-value mats are SGS certified, and R5.8 and R8.8 are suitable for four seasons and extremely cold environments ≥-20°C. (*If you are sensitive to the cold, we recommend purchasing a mat with an R-value 0.5R higher than the normal application temperature.) [7cm thick for a comfortable sleep] Naturehike high R value mat has high cushioning properties, and its thickness of 7cm eliminates bumps in the car and unevenness on the ground, making it difficult to feel unevenness and ensuring a comfortable sleep. In addition, you can adjust the thickness by 7-9cm by inflating it to your desired hardness. Note: Due to the structure of the air mat, it becomes larger as it fills up, and it is easy to mistakenly think that it is already fully inflated. In fact, it can be firmly supported even when pressed by hand, and can be inflated to a state where the lower left part does not touch the bottom.
