Roughly what temperature would a jacket with 133gm Prmaloft Gold be good in, sitting still, not moving? I know nothing is exact, but trying to get an idea what this would compare to.
Probably comparable to a 650 file down coat I'd say? With a good mid layer I'd say between 30-40f for stationary hunting. Maybe push it down to 20f with a good wind break over it and if you run hot. At least that's around the temps I get out of my synthetic puff with similar fill.
