I am looking for a light weight, easily packable down jacket. It will mostly be used while skiing and snowboarding in the Colorado backcountry as a mid layer under my hard shell jacket, as well as probably an outer layer hiking and biking in cool temps. I know it weighs a bit more, bit how does this jacket compare in bulkyness to Patagonia's Ultra Light Down Jacket? I have also been looking at MontBell's Light Down Jackets because they are pretty much unnoticeably light. Does anybody know which type of down jacket would be best for backcountry skiing in Colorado?
