For women who want real warmth on cold, slow chairlifts and breathability on hard-charging descents, the athletic-fitting Northwind MTN-X Hybrid Jacket is the ideal choice. BREATHR Down technology works to make the Northwind a warm, insulating layer when you’re sitting still 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.
