Naturehike Camping Sleeping Mat, 7cm Thickened Ultralight Inflatable Mattress With 3.5 R Value,High Value Excellent Warmth Retention4 Season Pad (Summer To Winter)

EIGHT LAYERS FOR TEMPERATURE SECURITY AND COLD PROTECTION: All inner layers are covered with aluminium foil to further separate the individual air chambers, which reduces heat loss and significantly increases warmth and weight. The R-value of the inflatable mat from Naturehike is 3.5 and is therefore suitable for use in cold environments above -6°C. The R-value is a measure of thermal resistance. The higher the R-value, the more difficult it is for heat to flow through the material and the better the insulation! FLEXIBLE PILLOW: Naturehike's inflatable sleeping pad combines high elasticity and pressure resistance to block the ground. The thickness of the inflatable pillow can be up to 7~9CM according to the inflatable volume, with excellent moisture absorption performance. It is a must-have for travelling! MULTI-POINT SUPPORT DISTRIBUTES PRESSURE EVENLY: Designed with an ergonomic structure to conform to the curves of the body. Spot-welded pattern for more stability. The air cushioning is soft and comfortable. When lying down, the pressure is evenly distributed through each contact point, creating a soft and supportive feeling that soothes and relaxes. You can also enjoy the comfort of home when travelling! LIGHT & PORTABLE: Only about 545 grams! Reduce the pressure of travelling weight. Stored correctly, it fits in a compact bag, is easy to transport and takes up little space. Travelling without a burden! DEFLATION: The valve opens only the outer layer to inflate on one side to prevent the air from escaping, while the valve opens both layers to deflate quickly to increase efficiency. To inflate, simply open the valve of the first layer of the air cushion, align the opening of the air bag with the valve and fully inflate the bag, then squeeze the bag to allow the air to enter the air cushion several times to complete inflation.
