This is the layer you want to extend your season—it's light and lets you move, but it's also incredibly warm. The best part? The ColdGear® Reactor insulation actually adapts to your activity level to keep you cooler when you start to get too hot.
Loose: Fuller cut for complete comfort. UA Storm technology repels water without sacrificing breathability. Lightweight, low-profile insulation embedded between two layers of performance fabric for the ultimate mix of warmth & breathability. Welded quilting allows the free flow of insulation for more even distribution. Stretchy side & back panels for better mobility.
