I bought this jacket and it immediately became my favorite piece of clothing, hands down. My work requires me to live outside every other week year round and this jacket is with me from October thru April. I wear an Icebreaker wool base and this jacket over the top and am perfectly comfortable 90% of the time. When it gets reeeaally cold, this wool jacket is roomy enough to layer a puffy down jacket under it and then I'm good to about -20F. Of course the wool stands up well when hanging out around campfires all day too. The hood has a very roomy cut which I appreciate as well. On cold nights I will even sleep with it on as it feels like your favorite cozy blanket on the inside. My only complaint is that after a year of use, the zipper sometimes comes off track. Highly recommended!
