Rab Inflatable mattress Ionosphere 5.5

The greatest attention has been paid to the thermal comfort of this insulating self-inflating mattress, which still needed to remain compact for climbers and adventurers in winter. With its TILT thermo-reflective liner and Stratus™ R insulation that retains heat, it reduces heat loss through radiation and convection, so you can have a good night's sleep on a rock face in extreme cold or under the stars at altitude. Count on lightweight and comfort during your long-distance ski hikes, fast-paced walks, or multi-day climbs.
