Best winter riding coats?

I am thinking of treating myself to a nice riding coat in the new year, especially if I can find some good sales. What are your favorites for riding? I like long coats because they cover my legs, but they must have slits on the side or a front that opens from the bottom for riding. The warmer, the better, as I ride in very cold, below freezing weather and snow. A hood is nice, but a high collar even better since I'd be wearing a helmet anyway, but I like a collar that covers my neck.

I've been eyeing the Equidry coat out of the UK, but they are so oversized, I think it would annoy me. I understand that they are made to fit over many layers, however, I have having a lot of extra material flopping around. And since I'm short, I feel like I would just feel lost in it.

I have a great riding skirt so a shorter coat would also work with my riding skirt if you have suggestions for those. What are your favorite brands for winter riding?
