I wear my Atom Lt almost everyday, its a wicked mid layer, although it is a little on the light side (as the name mentions), so I've found myself with using some additional layers as well when using it in anything around 0C. I used to have a MEC puffy from a few years ago, dont think it's sold anymore, but wasn't a real fan. It felt kind of cheap and was pretty deprived of insulation. If you don't want to break the bank there is some nice stuff from last season on the last hunt. Heard of this website from a few people in a mountaineering class. You probably won't get the color you want, but some things are pretty heavily discounted even more so during holidays.
