I like the ITC SS4500 for an 8 oz 80/20 cotton/poly and the IND4000 for a 10 oz (this one has a double lined hood, so the hood is 20 oz). Add a "Z" to either model number for a ZipUp version.
The 10 oz is a nice warm hoodie. The weave is tighter than the 8 oz, so keeps out wind pretty well. Probably too warm for people in California, and the like.
These hoodies have longer arms and bodies than typical. They are not a bulky cut, and are side seamed. The cuff and waist elastic is better/tighter than any others I have seen.
S&S carries them. Price is better than J America, from what I have seen.
EDIT: I have at various points in time, and for various reasons, used Hanes and Gildan. Hanes has weak elastic and is cut on the bulky side (which some may prefer). Gildan is neither outstandingly bad, nor outstandingly good, but rather the definition of decent. The Hanes I used is the 9.7 oz 90/10 cotton/poly PrintPro, and they do print well. The Gildan was the 8 oz 50/50 18000 series ... gotta watch your temps with that much poly to avoid sublimation. If you need sizes above 2X, the Gildan maintains 4" increments all the way to 4X; whereas the ITC 3X is really a 2X by measurement; below that size the ITC sizing is consistent with a 4" increment between sizes.
