Breathable warmth and all-day comfort are difficult to deliver in one package, but the Northwind MTN-X Hybrid Jacket does just that. BREATHR Down technology is the crucial component, making the Northwind a warm, insulating layer when you’re riding the chairlift and a heat-dissipating layer when you’re on the move. The Mini Taffeta Ripstop fabric is durable and resistant to snagging and abrasion, while a moisture-wicking treatment helps keep you dry.
