This sleep mat is designed for hikers and bikepackers who want their gear to take up the minimum amount of space whilst still offering a comfortable nights sleep. Once inflated the mat is 5cm deep which provides a cushioning effect even on hard surfaces. Its air filled welded channels mould to the contours of your body offering full length support whilst you sleep. This Thermo model has Vango’s new ThermoFlex® Base Fabric on the bottom of the bag which has a reflective aluminium coating to keep the cold away and heat in. The Siliconised hollow fibre core increases the R rating from 1 to 4 without adding too much bulk to the air mat.
