Matelas gonflable ultraléger 5,8 haute valeur R, matelas de couchage chaud, portable, tente de camping en plein air, tapis simple résistant à l'humidité

About this item Eight layers for temperature protection and cold protection: all inner layers are coated with aluminium foil to further separate the individual air chambers, which reduces heat loss and significantly increases heat and weight. The R value of the Naturehike inflatable mat is 5.8 and is therefore suitable for use in cold environments above -20°C. The R value is a measure of thermal resistance. The higher the R value, the more difficult it is for the heat to flow through the material, and the better the insulation! Flexible cushion: The Naturehike inflatable sleeping pad combines high elasticity and pressure resistance to block the floor. The thickness of the inflatable cushion can be up to 7~9 cm depending on the inflatable volume, with excellent moisture absorption performance. It is a must for travel Multi-point support distributes pressure evenly: designed with an ergonomic structure to adapt to the curves of the body. Spot welded pattern for added stability. The air cushion is soft and comfortable. When lying down, the pressure is evenly distributed through each contact point, creating a soft and supportive feel that soothes and relaxes. You can also enjoy the comfort of home when travelling Lightweight and portable: the rectangular standard model weighs only about 590 g. Reduce the pressure of travel weight. Properly stored, it fits in a compact bag, is easy to carry and takes up little space. Travel without burden! Double-layer air valve, quick and stable filling and deflation: the valve only opens the outer layer for one-sided inflation to prevent air escaping, while the valve opens both layers for quick deflation to increase efficiency. To inflate, simply open the valve of the first layer of the air cushion, align the opening of the air bag to the valve and inflate the bag completely, then press the bag so that the air can enter the air cushion several times to complete inflation.
