The new generation in mat construction comes with the durable yet lightweight DownMat TT 9 LW by EXPED. Due to inner air tubes that are relieved from strain the pressure is evenly distributed over the shell. The separate air tubes, that can be single purchased are individually adjustable. If neccessary the air tubes can be repaired or replaced very simple. Even in space-limited tents two DownMat TT 9 LW by EXPED find space due to their adjustable width. A Schnozzel Pumpbag with Octopus-Adapter is included.
