The Denali is a well-made fleece jacket w/ solid build: seams and fleece a` la North Face quality (warm pocket, and standard number thereof). Users can depend on it for cold days dashing from house to cars and parking lot. It would be insufficiently protective if you have to stand under a glacial wind for extended time. my only complaint is that if you are a little skinny in the shoulder+upper arms areas, you will feel the rippling bulge on the fleece(and thick seams) due to the space left by your not being very stuffed in those areas. the Denali looks very fit w/ people that have a girth and large shoulder and upper arms. this is a recommended item even though the color choices are not topnotch. I would use it on a cold autumn walk, and probably use it under another parka when confronting subtemp in nasty mornings of February. Size Medium is a well-fit size as in almost snug to your body; whereas a Large, which is still not very long, will leave too much unused air under the arms.
