The symmetrically shaped self-inflating mat Sherpa 38 NX guarantees your high comfort. The construction with one layer of relatively large horizontal cavities saves the weight of the mat, while maintaining relatively high thermal comfort, and the cavities also form a pleasant wavy structure of the mat after being inflated. Grinding the top layer of the material increases its friction, so your sleeping bag will not slip off the mat. It is equipped with a double valve with high flow. After opening the top layer of the valve, the mat can be easily inflated thanks to the non-return flap without loss of pressure. By pushing the flap, the pressure in the mattress can be gently regulated. After opening the second layer, the valve is fully open and the mat can be easily deflated. The construction of wide horizontal chambers in two layers combines the maximum possible foam relief with the highest possible thermal resistance achieved by preventing air circulation in the mattress and separating the individual layers of the chambers with foam. When inflated, the wide chambers are shaped into cylinders, which significantly increase the comfort of the mattress. The package includes a repair kit and packaging.
