THERMAREST Mondo King 3D Outdoor Camping Mattress, R-Value 7.0, Size 2 Extra Large [Official Japanese Product] 30104

The most insulating mattress in Therm-a-Rest's lineup has been updated. The new Stratacore foam blocks cold air from the ground with a central foam layer, while simultaneously trapping body heat in a recessed area on the top surface for superior insulation. It's 10cm thick when in use. The mattress features a vertical perimeter that keeps the adhesive between the top and bottom fabrics tightly closed, allowing multiple mattresses to be stacked side by side. The stretch knit surface feels velvety, providing a comfortable sleep experience that's just like sleeping on your own bed. The twin-lock valve makes setup and teardown quick and easy. Weight: 2500g, Size: 76 x 203cm, Packed Size: 79 x 23cm R-Value: 7.0 (4-season) Thickness when in use: 11cm Includes: Stuff sack with pump function
