Thermarest Polar Ranger -20F/-30C

Size: Regular

The Thermarest Polar Ranger -20F/-30C is a fast and light down sleeping bag equipped to conquer the most extreme conditions known to man. For polar expeditions and high-altitude adventures that demand un-compromised warmth, the Thermarest Polar Ranger -20F/-30C has been designed with polar explorer Eric Larsen, to ensure that every component of the bag has been maximised for warmth even in Arctic settings. 

The Polar Ranger has been engineered with 800-fill Nikwax Hydrophobic Down, meaning it not only absorbs 90% less water than untreated down, but any moisture it does pick up will dry 3 times faster. A synthetic snorkel hood with magnetic closure helps seal in warmth, while keeping any exhaled moisture away from the bag. Side vents allow for custom ventilation should get get too warm, and free your arms while still in the bag. Thermarest's SynergyLink connectors link your bag to your sleeping bag, and as you'd expect there are also external loops to attach a quilt for extra warmth. FInally, the ergonomic Toe-asis foot pocket is designed around a baffled pocket of insulation to rapidly warm cold feet. Storage sack and compression stuff sack included.

Sizing

The Thermarest Polar Ranger comes in two lengths, Regular and Long. See the table below, and Thermarest size guide in the image carousel.
