The North Face Inferno Down Bag

This is a fortress for extreme alpine conditions, prioritizing warmth and roominess over packability. The generous cut and center-zip design make it incredibly comfortable for layering up, though you’ll sacrifice some weight and bulk compared to more minimalist, mummy-style bags.
