The Swing CO 850 is a sleeping bag from the brand Valandré, this range being the perfect combination of the flagship models Swing and Chill Out.
Designed for winter high mountain hiking, this sleeping bag will provide you with the comfort and warmth you need for a good restorative night. Its tubular cut and 18 compartments padded with 90/10 French duck down boasting a loft power of 650 CUIN+, will keep your body evenly warm, while remaining ultra-light and discreet with a weight of only 1.35 kg and a compressed volume of 11 litres for size M.
The Swing CO 850 adapts to all conditions, covering a wide temperature range with a limit down to -37°C and a comfort around -9°C. In addition to being resistant to abrasion and heat thanks to its nylon fabric sourced from Asahi-KASEI® in Japan, the bag can evolve by pairing with other models from the Swing CO and Bloody Mary ranges, providing a second layer that increases the retention of your body heat.
