Looking for suggestions on puffy jackets for my wife. Intent is to build a lighter layering system for a long pack in and camp near timberline for CO 1st rifle. Last year temps went down to zero. Want her to be comfortable while glassing in cold, windy conditions. Don’t have layering dialed yet. Anticipate something like a merino wool base, Eddie Bauer evertherm light jacket and then a heavy insulation jacket. A rain/wind jacket will be in the pack too. Perhaps add light mid-layer such as a Patagonia R1 for flexibility to that system.

Currently eyeing a Montbell Frost line. Other ideas?
