The superior KÜHL SPYFIRE® Down Jacket is lighter, softer, and stronger. One look and you know it’s different. Features more down at your core and less down under the arms and in high sweat zones where you need the freedom to move. Temperature regulating knit underarm gussets keeps you from overheating when you are on the move. 3D articulated patterning and reinforced overlays for durability. Matched by no one.
