1. See if the "three marks" are complete: the genuine Alai down jacket should have three marks: tag, collar mark and washing mark. There should be a security code on the tag, which can be used to verify the authenticity of the product. Make sure that all three signs exist and there are anti-counterfeiting codes on the tag.
2. Touch the inner lining: the inner lining of genuine Ailaiyi down jacket is delicate and soft. The wiring inside should be neat and orderly, without loose threads or seams. The lining of fake goods will feel rough, the wiring will be irregular and the thread will be loose.
3. Check the zipper and other accessories: the zipper of genuine Aileyi down jacket is YKK brand, and there will be YKK three-letter metal LOGO on the zipper, and there will be Aileyi logo next to it. Some counterfeit products will imitate these signs, so we should carefully observe the quality and details of the signs. You can also check other accessories, such as buttons and webbing, to ensure that their quality and workmanship meet the standards of genuine products.
