Naturehike Ultralight Camping Mat Inflatable Sleeping Pad 3.5R Value Durable Portable Air Mattress for Trekking Hiking Mountaineering Backpacking Outdoor

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: The standard mummy shape model only weighs around 440g! Reduce the pressure of travelling weight. Stowed properly, it fits in a compact bag, is easy to transport and takes up little space. Travelling without a burden! Note: This inflatable pillow from the Naturehike Mummy Series can be joined together with a rope to form a double air mattress. DOUBLE-LAYER AIR VALVE, FAST AND STABLE INFLATION AND DEFLATION: The valve opens only the outer layer for one-sided inflation to prevent air from 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 with the valve and inflate the bag fully, then squeeze the bag to allow the air to enter the air cushion several times to complete inflation.
