On your next winter camping trip, enjoy the highest warmth-to-weight ratio of any Therm-A-Rest air mattress by using the NeoAir XTherm Sleeping Pad. This lightweight pad insulates and cushions you from the hard, frigid ground below without tacking on the weight or bulk normally found in winter-worthy sleeping pads. ThermaCapture layers within the pad keep you toasty by efficiently insulating and reflecting heat back to your body to keep the cold ground from sucking away all your precious warmth. As you toss and turn, the durable materials resist jabs from rocky campsites, while the soft, no-slip top fabric boosts comfort and keeps you from slipping off your pad when you're sleeping on uneven ground.
