Jeff, i have a new r1 i'm not sure i'll keep. Its really nice, but it might be a regression depending on what you're looking for. The cut is maybe slightly wider, but it mantains a very similar overall fit. The front zip goes lower, and is easier to operate with one hand. The hood of the new one doesnt fit me as well as the old one (6'2, size medium) when its fully zipped up. It goes over my mouth, but if I'm looking strait ahead, the collar will tug up away from my neck a little bit, which I dont like. If I were 6' or a little shorter, it wouldnt be an issue though. In its favor, the grid pattern seems improved and its supposed to be more breathable. Also, i didnt own one, but the extra fabric around the mouth and the side zip make for an awkward flap when not in use, whereas the new R1 hood will get out of the way easier. Its kind of a coin toss between the two IMO, but I'm thinking I'll probably return mine since its more warmth than I generally need as a baselayer. Hope that all makes sense. Fit is overall very similar.
