Arc'terx nuclei hoody is a nice synthetic insulation layer - Arc'teryx Nuclei Hoody - Men's

The Nuclei Hoody is a nice addition to one's outdoors kit. It's warmth-to-weight ratio, packability, and included compression bag make it fantastic. I also like the fit as usual for Arc'teryx and overall am very happy with it. However, due to its lack of breathability, this is a jacket that I would only wear during colder temps for the most part. It's not as flexible and breathable as its sibling, the Atom LT. I actually give that jacket the edge due to its composite or hybrid design not to mention its superior hood adjustment/design. Anyway, I ordered a medium and am 5'11", 175lbs, have a 16"x34" shirt size, 42R for jacket size, and a 34" waist. Want to stay warm during winter especially during more stationary periods like during the evening at camp, then get a Nuclei Hoody :o)
