Im thinking about buying this sweatshirt for my girlfriend but i have acouple questions about it. first of all the inside of the hood has a silk like shinny fabric, what exactly is the shinny fabric on the front of the hoodie for? is it like a build-in scarf or is it like a zip up above your head to form a mask type of hoddie? if it is a build-in scarf, is it removable? can you please answer my question about the fabric on the front of the hoodie as soon as possible because her birthday is fastly approaching. thank you.
