Familiarity: I've put it through the wringer
I wear this jacket all the time here in Alaska. I wore it last late August in the Brooks range while sheep hunting where temps got down in the 20's. I wore it this November in Kodiak where temps were also in the 20s. This paired with a light baselayer underneath will keep you toasty. It also regulates heat well and I almost never sweat. It does not absorb water very well and Primaloft insulation retains about 96% of its insulation value while wet, so no worries if it does get wet. I'm about to buy my 2nd nano puff.
