Can Kaileshi down jacket be made in the extremely cold weather of MINUS 30 degrees in the northeast? I will stay outdoors for at least five hours?

Coordinate genhe city, the average outdoor temperature in winter is below -30℃. Although there is heating in the room, it is really cold outside. So when I buy down jackets, I always choose Kellogg, a brand that focuses on outdoor sports. Ordinary ones are really not resistant to freezing. If you want to stay for a long time in the environment of MINUS 30 degrees, it is recommended to choose pro800 tent, which can not only resist freezing and wet cold, but also has strong air permeability, which can prevent sweating and colds after outdoor sports. Very suitable for wearing in extremely cold weather.
