Polar expeditions and high-altitude adventures demand uncompromised warmth.
The Thermarest Polar Ranger -30C was designed with polar explorer Eric Larsen to ensure that every component of the bag was maximised for warmth even in Arctic settings.
Thermarest engineered the bag with 800-fill Nikwax Hydrophobic Down™ and features like a synthetic snorkel hood to help you enjoy arctic expeditions.
Explorers like Eric Larsen understand the severity of the arctic cold and they count on the uncompromising performance of the Polar Ranger. Storage sack and compression stuff sack included.
