90% Goose Down Duvet European Standard Super Soft for Hotel

When choosing down jackets, the insulation performance of the filling material is an important consideration factor. Common fillers include duck down and goose down. So, which one is better for keeping warm, duck down or goose down? Here is a detailed comparison:

Thermal insulation performance

According to search results, goose down usually has better insulation performance than duck down. The main reasons include:

Fluffness: The fill power of goose down is usually higher than that of duck down. This means that each unit weight of goose down can wrap more air, providing better insulation effect.

Velvet size: Goose velvet has larger and longer fibers, resulting in fuller velvet that can better lock in heat.

Locking holes: At the same density, goose down has more locking holes, which can effectively maintain body temperature.

experimental data 

An experiment showed that at the same initial temperature, wearing a duck down jacket and a goose down jacket can better maintain body temperature. Although the specific experimental data was not listed in detail in the search results, this conclusion supports the advantage of goose down in terms of thermal insulation performance.
