Staying warm without overheating is a crucial factor when transitioning between strenuous ascents and cold descents. The Cascade Insulated Jacket features strategically placed insulation on the front and sleeves to keep you warm and comfortable in key areas. The Polartec® Alpha® insulation retains heat when you need it and allows it to escape through its vents when it gets too warm. Combined with our wind-resistant front that still offers ample breathability and a completely uninsulated back to let excess heat escape, it is the perfect garment for your cold-weather adventures.
