Aluminum vapor deposition is applied to both sides, so the heat inside does not dissipate to the outside during use, and external moisture and cold air are also blocked. It has excellent heat retention and insulation properties. The intermediate layer is made of foamed polyethylene, making it softer and more comfortable to sit on. The aluminum sheet is particularly focused on the material and sewing of the edges. Oxford fabric, which is more than 10 times stronger than non-woven fabric, is used, and a superior sewing technique achieves gentle corners without fraying. This significantly improves the durability of the product. It is also ideal as a sleeping bag mat. Versatile: In addition to leisure activities, it can also be used as insulation under carpets, children's play mats, and emergency supplies. For outdoor use, it can be used for mountain climbing, camping, fishing, hiking, and watching sports, laid on the ground or a sheet, or wrapped around to avoid direct sunlight or as a cold shield. During camping, it can also be used as an inner mat under a sleeping bag in a tent, keeping your body temperature warm for comfortable use. Water-repellent, easy to carry: Water-repellent treatment makes it resistant to rain and dirt and quick-drying. It completely shuts out moisture, so you won't get wet even if you sit for a long time. If you are caught in a sudden rain while you are out, you can use it as an umbrella. If it gets dirty, just wash it with water or wipe it with a cloth for easy cleaning. Essential for emergencies: Protects your body from the cold during outdoor stays and stays in shelters, such as during earthquakes and tsunamis, and during car camping. It also reflects light in the hot sun, preventing high temperatures, and can be given to children as a precaution in case of emergency. Management number...r58-33-198
