What are the temperature limits to keeping warm with this jacket?
This jacket is pretty burly. The shell material itself is preeeetty toasty and it's 15K which is really waterproof/windproof. Throw in the removable bonded hoodie, and you're warm until about 0 degrees F assuming you're wearing a base layer. Beyond that you're going to need some extra insulation.
