Product details:

The North Face ThermoBall Insulated Jacket is back, bringing another season of lightweight, packable warmth to your backpacking trips, snow-covered ski slopes, and everyday life. ThermoBall insulation mimics the look and feel of down, trapping your body heat to keep you warm while you're on the move—it even compresses down so you can stow it in a pocket and take it with you wherever you go. And because it's synthetic, ThermoBall insulation stays warm when you get wet during a misreported "powder morning" that in all actuality is rain up to 8,000 feet.
