Please read my profile before purchasing. I will not answer questions if you haven't read the profile and description. There is some wear and tear, such as minor scratches and stains, but I think it can still be worn without any problems. There are faint stains on both sleeves. It doesn't seem to be a problem, but the elastic on both sleeves may be stretched out (I've included this just in case, as I've forgotten what it was originally like). Please only purchase if you understand that this is a used item that has been stored at home, so there may be odors and folding wrinkles. Please refrain from purchasing if you are not tolerant of minor oversights or if you are a perfectionist who is concerned about small details. The outer material is a shaka-shaka (nylon-like) material, and the inner material is thin but a warm fleece-like material, so I think it's suitable for winter outerwear. It's not thick overall, so it's good for active boys. Also good for sports! If you are looking for Mizuno, Reebok, Umbro, Adidas, Champion, etc., please consider this. Please only purchase if you understand that this will be a simple package. It will be compressed for packaging. Instant purchase OK.
