1. purchase channel: choose a formal purchase channel, such as the official website, an officially authorized offline store or a well-known retailer. The risk of buying counterfeit products can be reduced.

2. trademarks and labels: carefully check the trademarks and labels on down jackets. The real Bosideng down jacket will have a clear and fine trademark and label, which indicates the quality and credibility of the brand. Pay attention to check whether the spelling, font, position and details of the trademark are consistent with the genuine product.
