Make every day legendary with the unmatched performance of the SPYFIRE Jacket. Lighter, softer, and stronger than anything in its class, the innovative SPYFIRE features more down at your core and less in heat-producing, high-mobility zones. Temperature regulating, knit underarm gussets release excess heat for sustained comfort during high-energy activity. Reinforcing overlays double the durability while 3D patterning provides your ideal fit. NEVER SETTLE.
