Like most Patagonia products, the pullover is well made. Warmth was similar to the Patagonia Down Sweater jackets except that it's cut with a roomier fit. I own both products in size Medium. The cut of the Down Sweater is slimmer, and doesn't allow as much room for layering. The Pullover renewed here is a fuller cut, almost to full, and with thicker layering is probably warmer. For my taste it's too roomy to wear over a just light shirt...you have to layer. I'm 5"8 and 168 lbs and wear a medium, but if I was 10 lbs lighter I'd have tried a small size for a less roomy fit.
The only reason for the 4 stars is that it's cut a bit full for my taste. And if I'd gone to a size small, the sleeve length might have been a problem.
