Anybody have one of these? Would you take it as your main jacket for a sheep hunt or would this be too much? Any concerns about the down for a main jacket. I understand it has a water resistant shell and treated down. I'm thinking for a layering system 1. Smartwool shirt, 2. Under Amour hoodie, 3. Kuiu down jacket, 4. Rain jacket. The Kuiu would replace a wind stopper fleece I've been using. Definitely lighter.
