The remarkable SPYFIRE Down Jacket is lighter, softer, and stronger. One look and you'll know it's different. Features more down at your core and less under your arms and high sweat zones where you need the freedom to move. Temperature-regulating knit underarm gussets release excess heat for sustained comfort during high-output activity. Reinforced overlays provide durability while our 3D patterning supplies the ideal feminine fit. MATCHED BY NO ONE.
