Warmth and application scenarios
The main difference between the down jacket with 75% and 90% down content is the warmth performance and the applicable scenario. Down jackets with 75% down content have moderate thermal insulation performance and are suitable for general cold environments; The down jacket with 90% down content has better thermal insulation performance and is suitable for extremely cold environments

Down content refers to the proportion of down in a down sample, which is generally expressed as a percentage. The higher the down content, the better the warmth of the down jacket. In down jackets with 75% down content, the proportion of down is 75%, and the rest are feathers or other fillings; In a down jacket with a 90% down content, the proportion of down is 90%, and the rest is feathers or other fillings

When buying a down jacket, you need to pay attention to the following:

Down content not less than 50%: Clothing with a down content of less than 50% cannot be called a down jacket
Pay attention to the quality of the filling: The down content of high-quality down jackets is generally more than 90%, avoid buying down jackets that contain a lot of down silk
Choose the right thickness: the filling capacity of light and thin down jackets generally ranges from 40-90g, the filling capacity of short down jackets of general thickness is about 130g, and the filling capacity of medium thickness is about 180g.
