High quality 650-fill down insulation for the high altitudes and low temperatures.

Whether you're summit bound or anticipating record low temperatures Mountain Hardwear's Sub Zero Jacket with 650-fill down insulation is the warmest jacket you'll find outside of an 8000-meter full-body mountaineering suit. It's a perfect frigid weather companion for backcountry snowshoeing skiing and alpine climbing especially if you prefer wearing your own hat or if you often wear a helmet. If the down insulation wasn't enough the handwarmer pockets are lined with fleece fabric for enhanced comfort. The Mountain Hardwear Sub Zero Jacket also comes with a stuff sack for storage or packing during warmer weather. If other jackets leave you in the cold this is a roast-toasty solution to your winter weather woes.
