This is a 3-ten special order NANGA Aurora 1000DX khaki long sleeping bag. I purchased it about 3 years ago and only used it 3 or 4 times in the winter, so I think it's in good condition, but it's still a used item. Please check the images and make your own judgment before purchasing. After use, I dried it with a futon dryer and stored it in a mesh bag. Extreme cold/snow mountain 3000m use!
