NY is genuine. The MY on the hat is not a special symbol, but the MY letter is more suitable for designing on the hat, so it is more common. NY is a team from American Baseball League called Yankees, and its brand is named after this team. Mainly produces and operates sportswear brands, including hats, clothes, pants and so on. In the design, most of them are mainly sports and leisure styles, and the models are loose and fat, which is very inclusive of the figure. In addition, the brand attaches great importance to the water absorption and breathability of fabrics, which can keep the body fresh during exercise and leisure. Therefore, NY and MY are not the basis for judging whether they are genuine or not, but are determined according to the brand and quality of the products.
