Polar expeditions and alpine adventures demand uncompromised warmth. The Thermal-a-Rest Polar Ranger Sleeping Bag was designed with explorer Eric Larsen to ensure it was maximized for warmth even in Arctic cold settings. Certified by the Responsible Down Standard, the sleeping bag’s 800-fill Nikwax Hydrophobic Down repels moisture and stays warm in damp conditions, drying 3 times faster than untreated down without using dangerous PFCs. Connect the sleeping bag to a Thermal-a-Rest camping mattress with Synergy Link connectors.
Overlapping side vents open to allow arm use and customizable temperature control, and the Snorkel Hood controls frost created by breath and eliminates warmth-sapping cross drafts. The top of the Polar Ranger is lined with Lining to trap radiant body heat and retain warmth without adding bulk or weight. Designed with Zoned Insulation, it maximizes warmth and saves weight by intentionally placing fill where you need it most; using 60 percent of the fill on top and 40 percent on the bottom. Also, Thermal-a-Rest’s Toe-asis Foot Warmer Pocket is an ergonomic toe box that rapidly warms cold feet. Recommended for temperatures down to -20 degrees Fahrenheit (-29°C). Available in 2 sizes: Regular size fits up to 6’0″ height and weighs 51 ounces and packs to 16 x 9 inches; Long size fits up to 6’6″ height, and weighs 55 ounces and packs to 22 x 14 inches. Storage sack and compression stuff sack included.
