Hi,
I was looking at some down jackets for a coming trip to Murmansk which can have -20 days or lower and can be quite windy.
Then I found a NZ maker of jackets which look quite well made but they are more waterproof and wind proof designed for outback hunting in cold wet conditions. My understanding is their type of material they use is breathable but wind proof and water proof.
If I layer up correctly and get one of these jackets instead of a down jacket would I be just as warm as if I was using a down jacket?
Here's a example I have attached a photo.

Thanks,
