Heavy on warmth, light in weight—the Atom SV Jacket is built for harsh conditions. It’s the warmest in the Atom lineup, insulated with Coreloft™ for reliable heat retention, even when wet. The wind-resistant shell sheds light precipitation, while the breathable construction makes it a versatile outer or midlayer. Articulated patterning ensures unrestricted movement, and a clean, hoodless profile keeps the silhouette sharp and adaptable. Built for winter, designed for everyday transitions.
