The Polar Ranger cold-weather down is the lightest and most advanced high-performance sleeping bag for the most extreme conditions.
It uses the latest interior partitioning technology and includes highly compressible Nikwax Hydrophobic Down™ filling with 800 fill power, without perfluorinated compounds (PFC). This technical down preserves its loft and warmth for longer, even when faced with the extreme conditions of expeditions to the depths of Antarctica. It absorbs 90% less moisture and dries three times faster than untreated down, which represents a significant advantage during long trips where the bag must be dried regularly. The ultra-light exterior and interior fabrics are made from 100% recycled GRS-certified nylon to better respect the environment. A hood with a special tunnel closed by magnets traps heat while allowing moisture from breathing to escape, which preserves the loft of the down. Long, oversized protective flaps stop drafts. Two side ventilation openings allow you to regulate the interior temperature and extend your arms without losing the protection of the bag. Other features: Toe-asis™ insulated foot warmer section, SynergyLink™ connectors to attach the bag to the mattress, interior stuff pocket, exterior loops to attach a duvet or blanket for even more warmth and a zip closure YKK® anti-lock slide
