Thats a ton of down. Nearly double the Rab Neutrino and that thing is pretty darn warm.
14 oz is getting into the territory of what people carry on Denali. Not that I am arguing against needing that much for being stationary in the mountains in winter.
It is. But, it stops all the bs of doubling puffies, multiple mid layers, etc. I guess people don’t actually sit and glass in 20° F and below for hours, regardless of what they say. Because 5-7oz of down isn’t cutting it. You freeze with what the industry offers.
This season with this puffy and the Vivo Tundra boots, was the first season ever that I was completely comfortable while glassing for hours in sub 20° F weather- without shivering, rubbing my hands, getting up and moving, etc.
No more base layer, plus two mid layers, plus two Grumman’s (or a Grumman and a First Lite Chamberlin), and a rain jacket for wind; just put this over what’s worn while hiking, sit down. Done.
30’ish degrees, 30+ MPH sustained winds. Partner had (IIRC) T shirt, LS base layer, thick mid layer, Grumman, rain jacket- same for legs. He froze. I fell sleep.
