I've been a big fan of the waffle-lined hoodie for most of my life.  I have a couple dickies thermal hoodies that I got back in '06, and they have a white lining that seems incompletely affixed to the shell.  I just got one of the new ones, and it's of much better quality and construction.  No warmer than the old ones, but much nicer.  For one thing, the zipper is larger (easier to grab) and sturdier.  I zip and unzip my hoodies dozens of times a day, sometimes, so a sturdy zipper is pretty central.  Also, the lining on these new ones is dark in color, which seems to show grime and sweat stains much less.  In short, Dickies has done a great job improving this product in the past few years, and they didn't even up the price too much.  Oh, and also the pockets are much nicer now.  The pockets on the old ones always seemed to leak their contents.  Not these.  Great job, dickies!
