The Exped SIM Lights are comfy, durable and slip resistant sleeping mats. SIM stands for self inflating mat as they are filled with air chanelled foam which sucks air into the mat as the foam expands. The SIM Lights are the closest thing in the Exped range to a Thermarest mat. They offer a firm mat to sleep on with mid level insulation. The top of the mat is brushed polyester to stop you sliding off your mat during the night.
