The inflatable lightweight mattress has a construction of two separate chambers, so it provides high thermal insulation. The upper highly durable nylon material with TPU (thermopolyurethane) treatment resists mechanical wear and rough handling. Two doublelayer valves with nonreturn valve reliably retain the required inflation level. The underside of the mat is equipped with an antislip print, so it does not slip on the floor of the tent or bivvy during use. In case of damage to the mattress, a repair kit is included in the mattress package. However, if you do not have a repair kit at hand, the mattress can be used with only one chamber inflated. The package also includes a waterproof rollup cover, which also serves to inflate the mattress. The mattress is predestined for more demanding climatic conditions from autumn to spring. The overall low weight (870g) and high durability and quality of workmanship of the mattress with overall performance makes it an ideal choice for winter alpine activities. The mattress is slightly lengthened and widened compared to the standard dimensions of sleeping pads.
