For those with toddlers in cold climates. What do you / are you going to do about coats?

A local car seat tech recommended a Patagonia type down sweater coat because it's so compact. I have one and it is extremely warm and will work well for door to car. Perhaps I'll just leave a shell at daycare for when they go out to play?

Does anyone else have a down sweater coat from another brand? I have my Patagonia from my last job but I'm not paying that for a toddler!
I'm thinking Columbia or Land's End might be cheaper but are they as warm?
