I have some questions about this north face jacket., http://www.thenorthface.com/catalog/sc-gear/womens-jackets-vests/womens-tka-100-glacier-full-zip.html I am buying this online so I can't really tell what it's like. So i was wondering- 1) is it like a thick fleece or is it really light? 2) could I possibly wear a hoody under it? I know online it says its light-weight. but I was just wondering if any of you guys have this jacket and could answer those two questions. Thanks! Much appreciated!
