I live in the Pacific Northwest and bought this to replace my current puffy vest/rain jacket combo. It would be perfect for anywhere with mild but wet winters, or chilly fall and spring transitions. The fit is more flattering than most Barbour jackets, especially if you have broader shoulders or a larger chest but don’t want to size up for fit or look bulky (I am smaller on the bottom and dislike Barbour styles with gathered waists which don’t flatter my body type). I am a 4/27 in pants and a medium or large/8 or 10 on top, and the UK 14/US 10 was the right size for me.
