L size. Please see the 4th photo for detailed measurements. Made of 100% cotton, it absorbs sweat easily and I think it will be comfortable to wear. Since it's stored by a private individual, there may be some overlooked minor stains. A sticker was attached to the tag, so there is a slight stickiness remaining, but it does not affect the product itself. Although it is new and unused, please purchase only if you don't mind that it has been stored by a private individual! I will fold it up small for shipping, so please be aware of any creases.
