Choosing the thickness of your down fabric depends largely on your usage environment and personal preference. Generally speaking, the thickness of down affects warmth, weight and breathability.

The first thing to consider is the usage environment. If you are often outdoors in cold winter, then it is recommended to choose a thick down fabric for better warmth. And if you only wear down clothing for outdoor activities in spring and fall or in a warm indoor environment, then it is more appropriate to choose a thinner fabric.

Next, consider your personal preferences. Some people prefer thick down garments because they can give a very warm feeling. Others prefer lighter fabrics because they are more breathable and comfortable. Therefore, when choosing the thickness of the down fabric, it is also important to consider your own preferences and how you feel when wearing it.

Finally, the quality of the down fabric should also be considered. Down fabrics of different thicknesses may also vary in quality. Generally speaking, high-quality down fabrics will be better in terms of warmth, breathability and durability, so try to choose better quality fabrics when making your selection.

Overall, the thickness of down fabrics should be selected according to the usage environment, personal preference and fabric quality. I hope the above suggestions can help you better choose the right down fabric.
