and heat can be expected here and that's what she does. In Camping under the bed / sleeping pad it has proved itself very well. Immediate reflection of heat and no penetration of cold from below at ambient temperatures of partly to 8 degrees Celsius at night. The mat is very light (about 280 grams). The pack size for "Auto Camper" not important. I have total 3 pieces of them and none broke down on holiday or located by. I would buy them again at any time.
