I too love down jackets, but unfortunately with having to open and close barbed wire gates all day I am scared of poking holes in a down jacket. Most down coats/jackets I have owned have never had a tough outer to keep from the stuffings from coming out and looking like a half plucked chicken if they get ripped. I do wear a down vest under my coat but I broke the zipper on it yesterday *sigh*
I do wear a lot of layers- thermal shirt, long sleeved shirt, a hoodie or wool sweater(depending on how cold it is), a down vest and a coat. I am trying to lighten the load some..LOL!
I used to wear Carhartt coats but started to hate to them. The last one I had was a chore coat. It was a little long and the back of it would always get hung on my cantle and it was heavy. I will look at them again though :)
I also looked at the Mountain Horse coats, this one in particular- http://www.mountainhorseusa.com/outerwear/mountain-horsemountain-rider-jacket-302111
But I have never seen one in person.
Looking at some of the ski jackets too.
I used to have a snowmobile jacket-very warm, but they are so stiff!
