Just wondering if the DAKINE Device Full-Zip Hooded Sweatshirt (http://www.backcountry.com/store/DAK0997/DAKINE-Device-Full-Zip-Hooded-Sweatshirt-Mens.html) was warm enough to chill in during the winter, i'm looking for somthing warmer that a sweatshirt, but not was bulky/warm as a ski jacket. Lay me down some feeds.
