Vango Viper Sleeping Bags are the flagship range of Vango down sleeping bags. These are 90/10 goose down bags with 580+ fill power down and Advanced Trapezoid Construction (ATC) angled chevron baffles which prevents the down from shifting and increases thermal efficiency by slowing heat loss comparable to similar rectangular shaped baffles. Complete with four panel profiled hood cinches in around the users head, the Vipers will withstand the that harshest of conditions and ensure heat loss is minimised.
The Vango Viper 1000 is the king of the Vango down sleeping bags and offers fantastic 5-season performance but still weighs in at well below 2000g and will only take up a tad over 10 litres of your rucksack space - a worthwhile sacrifice for the level of comfort it provides.
