Cabras Mac Jacket from Banana Republic Factory. 

"I love it because it goes with everything and it instantly makes what you’re wearing more sophisticated. Mac jackets are water repellent, so you can wear it in the rain, but they also keep you warm enough when there’s a breeze.

Also, BIG POCKETS.

I usually wear this jacket when running errands out in town, and it gets lots of use in the fall and spring, when it’s just cold enough outside for a light jacket. GQ says, “The water-repellent outerwear staple delivers the same British gentleman vibes as your classic trench, but in a stripped down, not-so-stuffy silhouette.” Couldn’t agree more."
