I grew up in Scotland, and everyone wore Barbour. It's very practical, it's very outdoorsy. It's what the gamekeepers and the fishermen and the farmers would wear.

I'm kind of obsessed by Everest and all those men that mountaineer and take themselves to extreme limits. Having gone back to Scotland to work on Outlander, I've been climbing a lot and getting out in the Highlands.

I've always been into endurance sport, which I think is more about your mind pushing your body, which is definitely why that Bear Grylls book sung to me.

It's hard to make a book episodic.

I love the outdoors, I love climbing mountains. But I also like to walk down the street in New York in the fall and go to a bar. So what I require of a jacket is different, but it still has that heritage.

It sounds almost unreal, but I was born and raised on old castlegrounds - Kenmure Castle.

The local shepherd, I vividly remember his old Barbour jacket, with a hipflask in the pocket. It just feels very familiar - like part of my childhood. The smell of the wax. Whenever I put one on now, it just feels comforting.
