THERM-A-REST - POLAR RANGER -20F/-30C

Designed in conjunction with renowned polar explorer Eric Larsen, the Polar Ranger -30C down sleeping bag is built for the coldest places on earth. Previously a recipient of Backpacker Magazine’s Editor’s Choice Award, the lightest and most feature-rich bag in its class just got better. It utilizes cutting edge box-baffled construction and is filled with highly compressible, PFC-free 800-fill Nikwax Hydrophobic Down™. This advanced down maintains its loft and warmth longer, even in the challenging conditions of extended expedition use in the arctic cold. It absorbs 90% less water and dries 3x faster than untreated down—a big plus on long trips where periodic drying is required. The ultralight shell and soft liner are made from planet-friendly GRS-certified 100% recycled nylon. A unique snorkel hood with a magnetic closure helps seal in warmth while routing exhaled moisture away from the bag to preserve loft. Drafts are kept at bay by extensive, overstuffed draft tubes and a pair of side vents allow for custom ventilation while freeing your arms while still in the bag. Other features include an insulated Toe-asis™ foot-warming pocket, SynergyLink™ Connectors to link bag and sleeping pad, an interior stash pocket, external loops for attaching a quilt or blanket for more warmth, and an anti-snag YKK® zipper.
