Therm-a-Rest Polar Ranger -20 Sleeping Bag : $489.99

The Therm-a-Rest Polar Ranger -20 Sleeping Bag is a technical down sleeping bag designed for mountaineering and polar expeditions. Comfortable down to -20°F, this bag is optimized for extreme cold weather environments. The 800-fill goose down is lofty, lightweight and compressible, and it's treated with Nikwax™ for enhanced water-resistance. The snorkel hood is packed with synthetic fill to prevent condensation from your breath. Side zippers allow you to vent excess body heat in warmer temps, but they also double as armholes so you can do your camp duties without being exposed to frigid conditions.
