I am a big fan of uninsulated tops, usually with a vest. On the other hand, about any time I wear a pair of bibs it's truly nasty. If I could I would have a pair of uninsulated bibs and a pair of insulated, but if it's one of the other it's the latter. I love and own some GWW, but I wound up buying Cabela's wooltimate bibs in outfitter camo--some over the top name like the "Stand Hunter Extreme". I had to go up a size because of all the insulation, but they are great with leg zips, good pockets, kidney pockets for heat warmer packs, etc.. I'm sure GWW would be better in many or most ways, but that kind of hunting is not a big priority for me.
