I'm selling this because I haven't had a chance to wear it since I lost weight. It has been washed and stored. (No pets, non-smoking environment) I don't remember the model, as I bought it several years ago. It's in good condition with some signs of wear. There's no logo on the chest, it's located on the upper arm area. The fabric isn't thick, so it's recommended for spring or autumn wear. The fabric is different under the arms, which is perfect for when you sweat. Please consider purchasing, understanding that this is a used item. I will ship it out on the same day if possible.
