1, better thermal insulation effect: down vest is filled with down, which has good thermal insulation performance. Down has many Suu, and there are many small gaps between silk, which can effectively prevent heat conduction and provide better insulation effect. In contrast, the thick vest is fleece, which can provide a certain warm effect, but compared with down, the warm performance is slightly inferior.

2, light and comfortable: down vest is relatively light and comfortable due to the light characteristics of down, and will not bring too much burden to the body. However, the velvet vest will be heavier because of the characteristics of the filler, which will bring a certain sense of burden to the wearer.
