At just 14.9 ounces for a size long, the Nunatak Arc Ghost is among the lightest 32 °F (0 °C) rated bags on the market. It achieves this light weight through its simple design: it features a closed foot box but an open, zipperless back. The back can be closed with two adjustable straps and a snap-closed neck with cinch cord, or it can be left open and used as a blanket. Not just lightweight, this "Variable Girth" design increases versatility, allowing the bag to be used within a wide temperature range by adjusting its circumference. A warm hat, hood, or balaclava is needed in colder temperatures as no hood is provided with the bag.
