NIKE Nike Golf Polo Shirt Men's Navy 3L-4L Equivalent This item is a 3L size from overseas, so I am listing it as a Japanese 4L size. It is used, but the condition is relatively clean, with no noticeable stains or blemishes. I think it can be used for both golf and casual wear. Please refer to the images with the measuring tape to determine the size, which is equivalent to 4L. Please check the images and consider purchasing.
