Familiarity: I've put it through the wringer
This is one of my goto winter pieces for sure. I bought it for layering for mountain biking and it does great at that being windstopper fabric. However I find myself using it for almost everything but extreme cold. For riding great for me anywhere from low 40s down layering differently lower I go. With a merino baselayer and thermal jersey I have used it in extreme cold, other times might just go wicking baselayer and no real additional thermal layer. Off the bike I tend to use it for short walks, runs, where I just want a little bit of warmth and the wind off me, especailly if I want head and neck covered tightly, I can still fit a thin wool beanie underneeth it. Also since the fit is made to go under helmet I can still use a regualr headlamp with the jacket.
It is not super slim fit like Gore's road bike jackets which I also own but comfortable with a thin sweater, too slim through the armas and with the cycling cut short up front with a longer or thicker sweater.
