I'm basing this review mainly on fit and quality, since I haven't had a chance to wear it much yet (I live in Houston). The fit and quality are both beautiful. I started off with a M, because a Woolx hoodie I'd previously bought was a M and I liked the fit, but I had to exchange it because it was too tight for any layers underneath. The L fits great and is really flattering. For reference, I'm 36C/28/38. I wore it this morning (about 35 degrees F) with a merino baselayer and a windbreaker on top and was very comfortable. I was afraid I might be cold without the windbreaker, but maybe not. It's a dense/heavy knit, not as fluffy and cozy feeling as fleece, but still a really nice jacket.
