Therm-a-Rest PolarRanger -20F/-30C Long Flame

Polar Ranger -20F/-30C Sleeping Bag. The lightest, most feature-rich down sleeping bag designed for the highest demands in extreme cold.

Developed in collaboration with polar explorer Eric Larsen, the Polar Ranger -20F/-30C sleeping bag is made for the coldest places on Earth. The Polar Ranger received the Editor's Choice Award from Backpacker Magazine. The lightest and most feature-rich sleeping bag in its class is now even better. The interior features a state-of-the-art chamber construction and highly compressible, PVC-free 800-cuin Nikwax Hydrophobic Down. This advanced down remains fluffy and warm for longer, even under the most challenging conditions encountered during Arctic expeditions. It absorbs 90% less moisture and dries three times faster than untreated down, which is a significant advantage during longer expeditions requiring intermittent drying. The exceptionally lightweight outer material and soft lining are 100%.
