1. Check with the Trademark Office in official website: If you have a brand you want to check, you can check with the Trademark Office in official website. When querying, you need to fill in the corresponding product information. If the query result is exactly the same product, it is true. If there are differences, it is false.
2. Touch the feel of the down jacket: If it is a real down jacket, it will feel very soft and the feather stalks on the down jacket are also complete. If it is fake, it will feel rough, and the feather stalk may be squashed or have long knots.
3. Shrinkage of down: Due to the great shrinkage of down, if it is a real down jacket, its volume will become very small after being stressed. If it is a fake down jacket, its volume will not become smaller after being stressed, but will become bigger.
