Symmetrically shaped mat for high comfort. The width of the mat is 55 cm along its entire length and does not narrow in the legs, so it is an ideal choice for those of us who like to roll over. The height of up to 4.5 cm ensures ideal damping of uneven ground. The construction with one layer of relatively large horizontal cavities saves even more the weight of the mat, while maintaining a relatively high thermal comfort. The cavities also form a pleasant corrugated structure of the mat after inflation. Grinding the top layer of material increases its friction, so you won't get a sleeping bag out of the mat. The high-flow double valve provides easy inflation of the mat without air escaping when closed. By pressing the valve, the pressure in the mat can be regulated when it is inflated.
