The opinion of Aventure Nordique
The Polar Ranger -20F/-30C from Thermarest is a down-filled sleeping bag for extreme cold. Designed with polar explorer Eric Larsen, it has several interesting features:
- Made of Nikwax Hydrophobic Down 800 cuin, it absorbs 90% less moisture and dries 3 times faster, RDS certified
- 100% recycled nylon outer fabric, GRS certified
- Hood with tunnel that retains heat and wicks moisture away from the breath, magnetic closure,
- Side openings (with protective flaps) that allow you to adjust the temperature and are very practical for putting your arms out while staying warm in the sleeping bag. Very practical for eating, studying the next day's route...
- SynergyLink connectors to attach it to the mattress to avoid cold bridges,
- Inside pocket big enough to hold your phone and external battery.
