The Soia & Kyo Judy long down jacket rates down to -4degF without giving up the close, stretch-fitted silhouette that usually gets sacrificed for that kind of warmth. Its 700+ fill power hi loft down traps heat efficiently enough that the coat can stay slim through the body rather than ballooning out to hit its temperature rating. A calf-length cut, hood, and in-seam pockets round out a coat built to work as hard in a real cold snap as it does layered over daily outfits.
