The Houdini One Eighty insulating jacket is incredibly versatile - it's reversible. One side of the jacket is made of light yet robust Spinner Ripstop™ material. The other side is made of C9 Ripstop™, which is extremely breathable. When you wear the C9 on the outside, you'll enjoy unparalleled airflow, and when you wear the Spinner Ripstop™ on the outside, you'll have a wind-blocking jacket with insulating properties. This is the perfect garment for unpredictable and variable conditions. The waterproof DWR finish is completely free of any harmful fluorocarbons and will easily withstand light rain showers. The minimalist design sports a chest pocket and push buttons. This jacket offers an excellent heat-to-weight ratio but, when the sun shines, you can quickly store it in its own pocket.
