Just came across this down skullcap on Massdrop. Looked nice but I wondered about the utility of such using down as the primary insulating layer. Fine for camp but not when wet or when one sweats a lot. Not exactly cheap either.

What are people's thought on this? Worthy piece of equipment or hardly worth it for the limited application?
