Summer cool is a thin cover that is covered in summer. It has good air permeability and good water permeability. Generally, it is not covered with a cover and washed directly. There are many fillers for summer cool, such as three-dimensional crimped cotton, microfiber, silk and so on. Summer cool is a wide variety and has different characteristics. 1. Traditional summer cool quilt Most of the traditional summer cool is mostly made of chemical fiber materials such as four-hole stable, seven-inch sputum, etc. Because of its fluffy appearance, it is easy to produce the illusion of warmth, but it can't absorb the air of the body, so it can't store heat for the body (recommended: red Carpet, red carpet meaning, red carpet price). This is the most unhealthy choice for those who are used to sleeping in the air or electric fans at night. The cheaper price is the biggest feature of traditional summer. 2. Towels are The towel is almost pure cotton material, breathable, light, sweat-absorbing, soft to the touch. It is suitable for people who are very afraid of heat, and the price is relatively cheap. 3. Thin cotton blanket The use of thin cotton blankets in Europe is very common and is intended for use by people who prefer to stay in air-conditioned rooms in the summer. The work is the same as the blanket, so it has the high quality warmth of the blanket and the super gas permeability of the towel, and the price is not expensive. 4. Duck down thin quilt The new type of duck down is very breathable and is especially suitable for the south where the summer climate is hot and the humidity is high. A good duck down quilt can absorb excess water vapor from the human body and discharge the water vapor into the air to keep the duck down comfortable. The quilt will not be flattened by water vapor, of course, its price is not cheap. . 5. Silk thin quilt Silk thin is especially suitable for people who stay in air-conditioned rooms for a long time in the summer and like to play quilts in the middle of the night. Light, warm and comfortable to the touch of the skin, is why many people like silk. In general, the price is moderate. Realpoo Optics is a professional manufacture of laser modules in the world.
