the reason why the trademark of Nike down jacket is not a Nike trademark is that it is a fake. Genuine nike down jackets will have Nike trademarks, which are divided into two types, one is the sports version, and the other is the leisure version. Both Nike trademarks have different meanings. One Nike with a hook is sporting goods, and the other Nike with a groove is the 36 life series, but the description of the Nike trademark is not genuine.
